IoT is disrupting almost every industry sector including communications. As power consumption has become a challenge for IoT devices, cellular IoT has introduced some standards that are cutting-edge. Let’s take a look at those standards and their device categories.

Remember the days when the “E” icon on the notification bar of our phones used to make us excited? 

Well, if we compare that to today, technology has skyrocketed like anything. It was just a matter of time before that E icon turned to 4G LTE.

Today, there are billions of devices that run on the 4G network providing lightning-fast internet to the users. And it does not end here. The wave of 5G is ready to take on the world. Though some countries have already deployed 5G, it is yet to conquer the entire world.

Now, IoT is not a buzzword anymore. It is an awesome technology that connects various internet-enabled devices and is known to everybody. The use of IoT allows devices to share data at a faster pace. But, there is one challenge!

As these devices are connected to cellular networks like 3G and 4G LTE, they consume a lot of power. In a way, it is acceptable, but not if the devices are sending a small amount of data occasionally. So what’s the solution here? Cellular IoT!

Cellular IoT deals with some of the best IoT standards and devices that make the existing cellular technology fit for low-powered devices. If you are interested to know how; read ahead and find out!

Why are IoT LTE devices necessary?

Well, the need for IoT devices comes into the picture when we analyze applications like predictive maintenance, asset tracking, fleet management, inventory management, remote service, etc.

All these applications are backed by powerful yet sensitive devices that transmit data to ensure that all your business processes are running fine. LTE is the technology that helps them. IoT devices under LTE can be classified based on the LTE standards!

LTE-M/ Cat-M1:

This standard covers devices that run under the bandwidth of 1.4 MHz. Most of the devices under the standard are smart meters, fleet management devices, and asset tracking devices.

Cat-1:

The operating bandwidth of Cat-1 devices is 20 MHz which allows for devices like ATMs, POS terminals, and wearables to operate.

Cat-4:

The devices under Cat-4 have the maximum download and upload speed, which makes them ideal for applications like autonomous vehicles, real-time video, and in-car infotainment.

NB-IoT/ Cat-NB1:

The IoT LTE devices under NB-IoT have the maximum latency, which makes them crucial for applications like parking sensors, street lighting, industrial monitors, and more.

What are the various IoT LTE devices categories?

Well, if we talk about the device categories, IoT LTE devices can be classified into four categories based on cellular IoT standards. The newest of these four standards are LTE-M and NB-IoT.

Let’s read ahead and find out about the IoT LTE device categories!

 

1. LTE-M/ Cat-M1

Let’s begin with the LTE-M standard. The LTE-M standard is an excellent discovery that is ideal for devices that require less power and less bandwidth. Here are some key pointers related to the device categories of LTE-M!

  • The devices based on the LTE-M standard have an upload speed of 1 Mbps, and the same is the download speed.
  • On top of that, the latency in the case of LTE-M devices is 10-15 milliseconds. The latency is enough to ensure that the required data is transmitted at regular intervals.
  • The bandwidth of the LTE-M is enough to ensure that the devices are able to function well in the prevailing 2G and 3G applications.
  • The best thing about the LTE-M standard is handoff for devices. It allows seamless handoff that makes the standard ideal for applications like asset tracking and fleet management where devices are on the move.
  • Cat-M1 was created as an integral part of Release 13 of the 3GPP’s LTE standards.

2. Cat-1

Apart from the above-described device categories, Cat-1 is a category that is a part of Release 8 of the 3GPP standard. Though it is a part of the old technology, it is still widely used across the globe. Here are some features of the Cat-1!

  • The Cat-1 standard is made for IoT device categories that have low and medium bandwidth needs.
  • The speed of the Cat-1 device is more than that of LTE-M. The upload speed of the Cat-1 devices is 5 Mbps, and the download speed is 10 Mbps.
  • One of the best things about Cat-1 is that it has less latency. The latency of the signals is just 50-100 milliseconds.
  • The Cat-1 standard uses a massive bandwidth of 20 Mhz in a full duplex. The full duplex capability of the devices allows for smooth handoff, making it ideal for wearables, ATMs, POS terminals, etc.

3. Cat-4

Well, the Cat-4 standard is what it takes to support applications like autonomous cars. The speed of devices in this standard is way more than Cat-1. It can provide you with 50 Mbps upload speed, and 150 Mbps download speed.

The best advantage of the Cat-4 standard is that it supports in-car infotainment, in-car hotspots, and video surveillance.

4. NB-IoT/ Cat-NB1

After the LTE-M, there is NB-IoT or Cat-NB1 standard. Just like LTE-M, there are many aspects that make it a bit different and unique. Here are some key pointers about the devices supporting the NB1 standard.

  • The low-cost technology makes use of DSSS modulation technology vs. LTE spread technology to ensure connectivity.
  • The cost factor of the technology is not the only USP. The devices that come under Cat-NB1 have less power consumption, offer excellent in-building coverage, and have longer battery life.
  • If we talk about the upload and download speed of the NB-IoT device category, it is relatively less compared to LTE-M. The upload speed is 66 kbps, and the download speed is 26 kbps. This is in half duplex mode.
  • The latency of NB-IoT is also more than the LTE-M. It oscillates between 1.6 to 10 seconds. Though it seems way more, there are advantages to it. The latency is ideal for small, intermittent data transmissions.
  • NB-IoT is also part of Release 13 of the 3GPP’s LTE standard. It is an LPWAN technology that works on a licensed spectrum.
  • The devices that come under this standard are smart gas, street lights, parking sensors, etc.

Other than these device and standard categories, there are two more standards:

5. Cat-0

As there is a need for low-cost devices and processes, Cat-0 lays the groundwork for that. It eliminates the need for features that require a high data rate in Cat-1. On top of all, Cat-0 is slowly doing the groundwork for Cat-M by replacing 2G.

6. EC-GSM

It is a standard that does not have as much buzz as the LTE-M and NB-IoT. But, it has been tested by brands like Ericsson and Intel for supreme practicality and modularity.

Why Do We Need To Care?

Well, if you are a cellular carrier service provider, you have to care about it. There are many factors that need to be considered while choosing the IoT LTE device category. Here is a brief elaboration of some of the critical ones!

10890699663?profile=RESIZE_710x

1. Power consumption:

Out of all the IoT LTE devices listed above, those who come under the Cat-4 consume the maximum power. After that come the devices under Cat-1. Cat-M1 and NB-IoT devices are the ones that have the minimum power consumption.

2. Battery life:

Battery life is the key factor if the devices are placed in remote locations like the agricultural field. If you are choosing LTE IoT devices, go for devices under standards Cat-M1 and NB-IoT.

3. Cost:

If cost is your concern, then again, Cat-M1 and NB-IoT are the ideal picks for you. They are best for high-volume device applications. Devices under Cat-1 and Cat-4 are more pricey.

4. Adoption:

When it comes to adoption, the adoption of LTE-M and NB-IoT are quickly being adopted by carrier service providers across the globe.

5. Latency:

Latency is the highest in NB-IoT, which makes it ideal for applications that do not need to send continuous data. LTE-M is a bit faster than NB-IoT. Cat-4 is the fastest, which makes it ideal for video applications.

Conclusion

So, now we are clear about what type of IoT devices are under each standard of LTE. LTE-M and NB-IoT are the standards that are being quickly adopted as they are low cost, consume less power, and have max battery life. To make an informed choice, it is necessary for you to analyze each aspect closely. As of now, carrier companies are inclined toward adopting  NB-IoT and LTE-M as they can serve vast applications while being balanced in all aspects.

What is GNSS positioning technology?

GNSS is the general term for all navigation and positioning satellites, that is, the Global Navigation Satellite System (Global Navigation Satellite System). BDS, GLONASS in Russia, GALILEO in Europe, etcetera. We can also simply understand it as a positioning system based on artificial earth satellites, which can provide accurate geographic location, speed and time anywhere in the world and in near-Earth space information.

The principle of GNSS positioning is NB Module based on the constant propagation speed of radio waves and the linear nature of the propagation path, by measuring the propagation time of the radio waves in the space to determine the distance difference between the satellite and the user receiver antenna. The distance difference, distance and measurement value, and then use these distance differences as the radius to meet the three spheres, and solve the user position according to the simultaneous equations;

First of all, any location on the earth's surface has its three-dimensional coordinates, that is, longitude, latitude and elevation. The GNSS satellite above its head also has its own three-dimensional coordinates. We can regard the entire space as a coordinate system, and we can draw a cube. The two opposite corners of the cube are the user and the satellite;

Secondly, based on the knowledge of solid geometry, we can know the distance △L between the satellite and the user (this distance is also called "pseudorange"); the equation is as follows:

The coordinates of the satellite are (x', y', z'), which are known, and the coordinates of the user are (x, y, z), which are unknown. At the same time, the satellite can send a signal to the user terminal, and the transmission speed of the signal is basically equal to the speed of light c, and the satellite has a highly accurate atomic clock, so it knows its own time is t.

The Internet of Things is changing the way we consume and interact with things in our everyday lives. IoT gives objects digital identity. This means that they can be monitored, controlled, and synced with other devices wirelessly. The article looks at how the IoT will affect the electric vehicle industry in the future.

Let's begin!

  • Final Thought

 

How will the IoT affect the Electric Vehicle Industry?

The IoT has the potential to change the way we interact with the world around us, and it is already having an impact on the electric vehicle (EV) industry.

One way that the IoT is affecting EVs is by making it possible for cars to communicate with each other and with infrastructures, such as traffic lights and parking spaces. This communication can make driving more efficient and safer. For example, if two connected cars are approaching an intersection at the same time, they can communicate with each other to decide who has the right of way. This eliminates the need for one car to stop and wait for the other to pass.

Another way that the IoT is impacting EVs is by providing data that can be used to improve the efficiency of charging stations. Connected chargers can communicate with each other and with EV batteries to optimize charging times and reduce congestion at charging stations. This data can also be used to help plan future charging infrastructure.

The IoT also has the potential to change how we think about ownership of EVs. In a traditional ownership model, a person buys a car and then pays for its maintenance, fuel, and insurance. With an IoT-enabled EV, it would be possible for someone else to own the vehicle and provide these services as part of a subscription service. This could make EVs more affordable.

What are the Advantages and Disadvantages of the IoT in the EV industry?

As the electric vehicle industry continues to grow, so too does the role of the IoT. The advantages of the IoT in the EV industry include increased efficiency and accuracy in data collection, improved safety and security, and enhanced customer experience. Meanwhile, some of the disadvantages of the IoT in the EV industry include potential privacy concerns and data breaches, as well as the need for a reliable and secure network infrastructure.

The Advantages of the IoT in the EV industry

  • It makes it easier for you to control your car's climate and other functions remotely while you're not in it.
  • You can use an app on your phone or laptop to control things like lights, power windows, etc., even if they're not connected directly to your vehicle's system (like a garage door opener). You could also use this tech for home automation systems like Nest or Harmony which allow you to control all kinds of things from anywhere in your house.
  • You can share information about where you parked your car with friends who might need help finding it later on or help them find it.

The Disadvantages of the IoT in the EV industry

The IoT is a great way to increase your EV industry's efficiency and success, but it can also be difficult to implement. Here are some disadvantages of using the IoT in the EV industry:

  • The cost of implementation is high. This may be because there are many different types of devices that need to be connected, and each requires different types of software and hardware.
  • The amount of data that needs to be collected can be overwhelming for some businesses, especially if they don't have experience with big data collection or storage systems.
  • There are many different types of devices that need to be connected some may not work together well or may require additional programming. So it can take time and money before you're able to see any benefits from your investment in the IoT system.

What Industries Have Benefited from the IoT?

The Internet of Things (IoT) has had a significant impact on the automobile sector. One of the most major developments has been in the manufacturing of cars. The introduction of sensors and other linked devices has enabled manufacturers to collect data on how cars are used, leading to changes in the production process. As a result, automobiles are of higher quality and more efficient.

Another area where IoT technology is making a difference in car safety is. Automakers can discover possible safety hazards and solve them by gathering data from sensors and other linked systems. As a result, automobiles are safer and there are fewer accidents.

Finally, IoT technology is transforming how customers engage with their automobiles. Customers are increasingly utilizing their cell phones and other linked devices to manage their automobiles.

Everything from starting the engine to opening the doors and controlling the temperature control is covered. As this trend continues, it is probable that even more capabilities that allow consumers to operate their automobiles in novel ways will be added.

Final Thought

The IoT will play a major role in the electric vehicle industry by providing real-time data that can be used to improve the efficiency of production and distribution. In addition, the IoT can also be used to monitor the performance of electric vehicles and provide feedback to drivers in order to help them optimize their routes and usage. Ultimately, the goal is to make electric vehicles more efficient, reliable, and affordable for everyone.

In battery-powered microcontroller applications, energy savings are critical. Reduce battery charging times and replacement time by reducing current consumption. Microcontroller software design should follow these guidelines to reduce current consumption:

1、Using the appropriate energy model

Utilize low-energy peripherals

Close unused modules/peripherals

Disable clock to unused modules/peripherals

Reduce the clock frequenc

Operating voltage reduction

Optimize the code

2、Using the appropriate energy model

The most effective way to save energy is to spend as little time as possible in active mode.

Five custom energy modes allow the microcontroller to operate in an energy-optimal state at any given time.

3、Utilize low-energy peripherals

All peripherals are built on energy consumption and can be used in a variety of energy modes. Whenever possible, select the appropriate peripheral to let it work while the CPU is sleeping (or performing other tasks).

A few examples:

Use RTC and sleep instead of waiting for a certain loop

Transfer data between memory and U(S) using DMA

Monitor sensors with low energy sensor interface (LESENSE) instead of wake up and poll

4、Close unused modules/peripherals

There are modules/peripherals that are not in use at any given time for each microcontroller application. Turn these off and save energy. This also applies to the CPU itself. If the core is idle (for example, waiting for data reception), you can turn it off and save energy. This is one of the main features of the different EFM32 energy modes. Remember to consider start and stop conditions when disabling peripherals. For example, if it is completely turned off, the ADC needs some time to warm up before the conversion can be initiated. Similarly, USART simultaneous transmissions should be allowed on the progress. Thus, the receiver's shift register will not be in an indeterminate state.

5、Disable clocks to unused modules/peripherals

Even if a module/peripheral device is disabled (for example, TIMER0 stops), the various circuits in the module will still consume energy if its clock is running. Therefore, it is important to turn off the clocks of all unused modules.

6、Reduce clock frequency

Current is plotted at clock frequency. Generally speaking, a task or peripheral device should run at the lowest possible frequency.

For example, if a timer requests interruption every few milliseconds, it should be locked at several kHz instead of several MHz. This can be easily achieved by pre-scaling in CMU. Similarly, one way to choose CPU frequency is that it should be so low that the CPU will not be idle (some blanks should be added). However, in many cases, it is best to complete the current task quickly and then enter the appropriate energy model until new tasks have to be addressed.

7、Reduce working voltage

By reducing the working voltage, the energy consumption is further reduced. The Gecko series of microcontrollers can operate at low voltage.

There are absolute minimum values in the data table of each device

8、Optimization code

Optimizing code usually reduces energy consumption byincreasing the speed and efficiency of programs.A faster program spends less time in active mode, and in amore efficient program, each task executes fewer instructions. A simple way tooptimize code is to build it in release mode with the highest optimizationsettings rather than in debug mode.

9、Energy model

The EFR32 provides features that make it easier to configurelow-power peripherals and switch between energy modes. The EFR32 providesfeatures that make it easier to configure low-power peripherals and switchbetween energy modes.
Let's take a look at several modes

9.1 Operation mode (EM0)

This is the default mode. In this mode, the CPU fetches and executesinstructions from flash or RAM, all peripherals may be enabled, and theoperating power consumption is only 63 μA/MHz.

9.2 Sleep mode (EM1)

In sleep mode, the CPU's clock is disabled. All peripherals, as wellas RAM and flash memory, are available. Automated execution of multipleoperations can be achieved by using a Peripheral Reflection System (PRS) andDMA. For example, a timer can trigger an ADC conversion at regular intervals.When the conversion is complete, the result is moved to RAM by the DMA. When agiven number of conversions are performed, the DMA can request and interrupt towake up the CPU. Enter the sleep mode or the "Wait for Event (WFE)"instruction by executing "Wait for Interrupt (WFI)". Use the functionEMUILATEMEM1 () to enter sleep mode

9.3 Deep sleep mode (EM2)

In deep sleep mode, no high frequency oscillator is running, whichmeans only asynchronous and low frequency peripherals are available.This model further increases energy efficiency while still allowing arange of activities, including:

Low energy sensor interface(LESENSE) monitoring sensor,

LCD monitor drives LCD monitor,

LEUART that receives ortransmits one byte of data,

Perform address matching check.

RTC wakes up the CPU after theprogram is coded.

Analog Comparator (ACMP) tocompare voltage to programmed threshold

A GPIO to check the conversionon the I/O line.

The deep sleep mode isto first set the sleep depth in the system control register (SCR), and thenexecute the "Wait for Interrupt (WFI)" or "Wait for Event(WFE)" instruction. Use the function EMU_EnterEM2() to enter the deepsleep mode.

9.4 Stop mode (EM3)

The stop modediffers from the deep sleep mode in that no oscillator (except ULFRCO orAUXHFRCO) is running.
Modules/functions, if present on the device, canstill be used in stop mode when the appropriate clock source remains active:

I2C address

Supervision

GPIO interrupt

Pulse counter (fund)

Low energy timer (LETIMER)

Low energy sensor interface (LESENSE)

Real-time counter and calendar (RTCC)

Analog comparator (ACMP)

Voltage monitoring (VMON)

Ultra-low energy timer/counter(CRYOTIMER)

TemperatureSensor

Stop mode is the same as deep sleepmode, except that the low frequency oscillator must be manually disabled

9.5 Sleep mode (EM4H)

This feature is called EFM32'shibernate mode and wireless SoC Series 1, and is enabled using dedicatedcontrol register logic. Write the sequence 0x2, 0x3, 0x2, 0x3, 0x2, 0x3, 0x2,0x2, 0x2, 0x2, 0x2 to the EM4ENTRY bit field in the EMU_EM4CTRL register, andplace the device in hibernate mode when the EM4STATE bit is set; otherwise, Thedevice enters shutdown mode as usual. In sleep mode, most peripherals areturned off to reduce leakage power. There are some selected peripheralsavailable. System memory and registers do not retain values. The GPIO PADstatus and RTCC RAM are reserved. Wake up from EM4 sleep requires a reset tothe system and return to the EM0 activity. Sleep mode wake-up is possible, fromthe same shutdown mode to the power loop, nRESET, and the user-specified pinsource, as well as:

RTCC

CRYOTIMER

 

Measuretemperature outside the defined range (TEMPCHANGE)

9.6 Shutdown mode (EM4S)

The shutdown mode is the lowest energystate of the EFM32 Series 0, EFM32 or Wireless SoC Series 1 microcontroller.
The power is turned off to most devices, includinginternal RAM, and all clocks are disabled. Only recovery logic, if the GPIO padstatus is explicitly enabled, is retained. Wake up from off mode alwaysrequires a reset. When resetting from a RESETn pin or through one of a set ofdevice-specific pins explicitly enabled for this purpose, the current drawingin off mode can be as low as 20na. Some devices can replace pin-based wakeups;however, waking up from these sources requires a low-frequency oscillator toremain active, increasing the current attractiveness.

What is edge acquisition?

1. Introduction to edge acquisition

Edge acquisition is to abstract data (such as ModBus registers) on external devices (such as ModBus devices) into internal data points of the device (E870-D1). Configuring and reading internal data points is equivalent to configuring and reading corresponding external data ( such as ModBus registers). External devices can be ModBus devices or other communication protocol devices, such as IIC, CAN and other bus protocol devices. Currently, Ebyte E870-D1 only supports ModBus devices. (This article takes E870-D1 as an example)

2. The principle of edge acquisition

Implementation principle of edge acquisition (taking ModBus device as an example): As shown in the following edge acquisition application topology diagram, when edge acquisition data points are configured, the edge acquisition device (E870-D1) polls and reads the data in the external device through the ModBus protocol. The register is transmitted to the cloud platform through 4G;GPS Module when the cloud platform configures the data point, the edge acquisition device configures the corresponding register of the external device through the ModBus protocol, thus realizing the transparent transmission and control of the cloud platform and the external device.

The data structure of each data point includes the following attributes: "Enable", "Keyword", "Slave Address", "Register Type", "Register Address", "Data Type", "Report Mode", "Report Time" ", "Range of variation", "Number of decimal places", "Read-write property", "Up formula", "Down formula".

Among them, "keyword", "slave address", "register type", "register address", "read and write attributes" are used to realize the association between data points and ModBus registers.

The "keyword" is the name of the data point, and the name cannot be repeated in an edge acquisition device (E870-D1). When the cloud platform reads/configures the external device through the data point name ("keyword"), the edge acquisition The device (E870-D1) automatically translates the data point into the corresponding ModBus register according to its "Slave Address", "Register Type", "Register Address", and "Read-Write Attribute" information.

"Enable" controls whether the data point is valid. Only valid data points can be read, configured and polled.

Other attributes "Report Mode", "Report Time", "Variation Range", "Number of Decimals", "Upstream Formula", "Downstream Formula" can implement simple edge computing, which will be described in detail below.
2. The difference between edge collection and edge computing: Huawei's definition of edge computing (URL)

Huawei's definition of edge computing is: Edge computing is a distributed and open platform that integrates network, computing, storage, and application core capabilities at the edge of the network near the source of things or data to provide edge intelligent services nearby. To put it simply, edge computing is to analyze the data collected from the terminal directly in the local device or network where the data is generated, without the need to transmit the data to the cloud data processing center.

It is not difficult to see from the comparison between Huawei's definition of edge computing and the first description of the nature and principle of edge collection in this article. Edge collection belongs to a part of edge computing, that is, the part where the terminal collects data. At the same time, Ebyte E870-D1 has the function of transmitting data to the platform.
3. Problems solved by Ebyte E870-D1 edge acquisition:

1. Communication between ModBus and the platform: The traditional ModBus device is only short-distance communication. It is difficult to achieve communication with the Internet platform. Using Ebyte E870-D1, you can use its edge acquisition function to seamlessly connect to the local area. ModBus device and remote cloud platform, so as to realize unified monitoring and deployment of many ModBus devices by cloud platform.

2. Reduce the pressure on the platform server: Ebyte E870-D1 can easily add and delete data points through the "enable" attribute of data points, reduce unnecessary data point uploads, and at the same time "report mode", "report time" ” and “Variation range” can control the reporting timing of data points and reduce unnecessary reporting times of data points. The above can achieve a data filtering effect.

3. Simple edge computing can be realized: through the "upstream formula" and "downstream formula", custom addition, subtraction, multiplication and division calculations can be performed inside the Ebyte E870-D1.
Fourth, the advantages of Ebyte E870-D1 edge acquisition over ModBus_TCP:

1. Another way to achieve remote control of local ModBus devices is to use ModBus_TCP mode, but ModBus_TCP is not suitable for frequent data exchange and small amount of data each time, because it will consume a lot of network resources and platform resources. .

Today's sharply increased number of edge devices are all small, sophisticated, and highly specialized, such as a variety of sensors, each of which cannot be equipped with networking capabilities, and a huge number of edge devices are directly connected to the platform through ModBus_TCP , the pressure on the platform can also be imagined. Ebyte E870-D1 edge acquisition function can solve this problem very well.

2. Can connect to multiple external devices at the same time:Wireless modem Ebyte E870-D1 can connect to multiple edge acquisition devices at the same time, and ModBus_TCP can generally only communicate one-to-one.

3. The built-in IO can also be abstracted into data points: I explained how to abstract external device data into edge collection data points. At the same time, the DI, DO, AI, and AO that come with Ebyte E870-D1 can also be abstracted into structures. The same data points, thus eliminating the difference between built-in IO and external device data (such as DI, DO, AI, AO, etc.), reading/configuring built-in IO can use the same data structure, which is very helpful for platform development .

5. Usage scenarios

1. Connect multiple industrial DI, DO, AI, AO equipment to realize the network upgrade and transformation of traditional equipment.

2. Connect multiple ModBus sensors to realize environmental monitoring of an area.

Against the backdrop of digital technology and the industrial revolution, the Internet of Things has become the most influential and disruptive of all the latest technologies. As an advanced technology, IoT is showing a palpable difference in how businesses operate. 

Although the Fourth Industrial Revolution is still in its infancy, early adopters of this advanced technology are edging out the competition with their competitive advantage. 

Businesses eager to become a part of this disruptive technology are jostling against each other to implement IoT solutions. Yet, they are unaware of the steps in effective implementation and the challenges they might face during the process. 

This is a complete guide– the only one you’ll need – that focuses on delivering effective and uncomplicated IoT implementation. 

 

Key Elements of IoT

There are three main elements of IoT technology:

  • Connectivity:

IoT devices are connected to the internet and have a URI – Unique Resource Identifier – that can relay data to the connected network. The devices can be connected among themselves to a centralized server, a cloud, or a network of servers.

  • Data Communication:

IoT devices continuously share data with other devices in the network or the server. 

  • Interaction

IoT devices do not simply gather data. They transmit it to their endpoints or server. There is no point in collecting data if it is not put to good use. The collected data is used to deliver IoT smart solutions in automation, take real-time business decisions, formulate strategies, or monitor processes. 

How Does IoT work?

IoT devices have URI and come with embedded sensors. With these sensors, the devices sense their environment and gather information. For example, the devices could be air conditioners, smart watches, cars, etc. Then, all the devices dump their collected data into the IoT platform or gateway. 

The IoT platform then performs analytics on the data from various sources and derives useful information per the requirement

What are the Layers in IoT Architecture?

Although there isn’t a standard IoT structure that’s universally accepted, the 4-layer architecture is considered to be the basic form. The four layers include perception, network, middleware, and application.

  • Perception:

Perception is the first or the physical layer of IoT architecture. All the sensors, edge devices, and actuators gather useful information based on the project needs in this layer. The purpose of this layer is to gather data and transfer it to the next layer. 

  • Network:

It is the connecting layer between perception and application. This layer gathers information from the perception and transmits the data to other devices or servers. 

  • Middleware

The middleware layer offers storage and processing capabilities. It stores the incoming data and applies appropriate analytics based on requirements. 

  • Application

The user interacts with the application layer, responsible for taking specific services to the end-user. 

Implementation Requirements

Effective and seamless implementation of IoT depends on specific tools, such as:

  • High-Level Security 

Security is one of the fundamental IoT implementation requirements. Since the IoT devices gather real-time sensitive data about the environment, it is critical to put in place high-level security measures that ensure that sensitive information stays protected and confidential.  

  • Asset Management

Asset management includes the software, hardware, and processes that ensure that the devices are registered, upgraded, secured, and well-managed. 

  • Cloud Computing

Since massive amounts of structured and unstructured data are gathered and processed, it is stored in the cloud. The cloud acts as a centralized repository of resources that allows the data to be accessed easily. Cloud computing ensures seamless communication between various IoT devices. 

  • Data Analytics

With advanced algorithms, large amounts of data are processed and analyzed from the cloud platform. As a result, you can derive trends based on the analytics, and corrective action can be taken. 

What are the IoT Implementation Steps?

Knowing the appropriate IoT implementation steps will help your business align your goals and expectations against the solution. You can also ensure the entire process is time-bound, cost-efficient, and satisfies all your business needs.

Set Business Objectives 

IoT implementation should serve your business goals and objectives. Unfortunately, not every entrepreneur is an accomplished technician or computer-savvy. You can hire experts if you lack the practical know-how regarding IoT, the components needed, and specialist knowledge. 

Think of what you will accomplish with IoT, such as improving customer experience, eliminating operational inconsistencies, reducing costs, etc. With a clear understanding of IoT technology, you should be able to align your business needs to IoT applications. 

Hardware Components and Tools

Selecting the necessary tools, components, hardware, and software systems needed for the implementation is the next critical step. First, you must choose the tools and technology, keeping in mind connectivity and interoperability. 

You should also select the right IoT platform that acts as a centralized repository for collecting and controlling all aspects of the network and devices. You can choose to have a custom-made platform or get one from suppliers. 

Some of the major components you require for implementation include,

  • Sensors
  • Gateways
  • Communication protocols
  • IoT platforms
  • Analytics and data management software

Implementation

Before initiating the implementation process, it is recommended that you put together a team of IoT experts and professionals with selected use case experience and knowledge. Make sure that the team comprises experts from operations and IT with a specific skill set in IoT. 

A typical team should be experts with skills in mechanical engineering, embedded system design, electrical and industrial design, technical expertise, and front/back-end development. 

Prototyping

Before giving the go-ahead, the team must develop an Internet of Things implementation prototype. 

A prototype will help you experiment and identify fault lines, connectivity, and compatibility issues. After testing the prototype, you can include modified design ideas. 

Integrate with Advanced technologies

After the sensors gather useful data, you can add layers of other technologies such as analytics, edge computing, and machine learning. 

The amount of unstructured data collected by the sensors far exceeds structured data. However, both structured and unstructured, machine learning, deep learning neural systems, and cognitive computing technologies can be used for improvement. 

Take Security Measures

Security is one of the top concerns of most businesses. With IoT depending predominantly on the internet for functioning, it is prone to security attacks. However, communication protocols, endpoint security, encryption, and access control management can minimize security breaches. 

Although there are no standardized IoT implementation steps, most projects follow these processes. But the exact sequence of IoT implementation depends on your project’s specific needs.

Challenges in IoT Implementation

Every new technology comes with its own set of implementation challenges. 

10661244498?profile=RESIZE_710x

When you keep these challenges of IoT implementation in mind, you’ll be better equipped to handle them. 

  • Lack of Network Security

When your entire system is dependent on the network connectivity for functioning, you are just adding another layer of security concern to deal with. 

Unless you have a robust network security system, you are bound to face issues such as hacking into the servers or devices. Unfortunately, the IoT hacking statistics are rising, with over 1.5 million security breaches reported in 2021 alone. 

  • Data Retention and Storage 

IoT devices continually gather data, and over time the data becomes unwieldy to handle. Such massive amounts of data need high-capacity storage units and advanced IoT analytics technologies. 

  • Lack of Compatibility 

IoT implementation involves several sensors, devices, and tools, and a successful implementation largely depends on the seamless integration between these systems. In addition, since there are no standards for devices or protocols, there could be major compatibility issues during implementation. 

IoT is the latest technology that is delivering promising results. Yet, similar to any technology, without proper implementation, your businesses can’t hope to leverage its immense benefits. 

Taking chances with IoT implementation is not a smart business move, as your productivity, security, customer experience, and future depend on proper and effective implementation. The only way to harness this technology would be to seek a reliable IoT app development company that can take your initiatives towards success.

The identity environment will expand enormously as the Metaverse takes traction and new applications and access points emerge alongside it, creating additional entry points for potential bad market players. Already, 84% of corporate executives concur that their company now manages significantly more digital identities than it did ten years ago (up to 10x). Additionally, 95% of firms say they have trouble keeping track of all the identities that are currently a part of their organization (human and machine). We have a perfect storm of rising complexity and expanding threat vectors that may be exploited, which can lead to breaches, business disruption, and material expenses when we add in the Metaverse and the rise in IoT usage that will accompany it.

Top features of IoT:

 a.) A 360-degree enhanced and real-world training: 

Using the IoT, we are able to develop and test training methods in situations where we are unable to do so in the real world due to the scope and authenticity of training on extreme real-world situations (such as severe weather or cyber events) that can be done through virtual simulations using digital twins in the Metaverse. Io Train-sim will aid in preparing people and AI/software to cooperate to better recognize issues and lessen the impact in real life as virtual metaverse environments develop to more closely resemble reality.

b.) Smarter and better long-term planning along with its near-term response: 

The metaverse system will increasingly closely resemble our real world as it fills up with digital duplicates of real-world objects (such as cars, buildings, factories, and people). We will be able to run different long-term planning scenarios, identify the most optimal designs for our energy, transportation, and healthcare systems, and dynamically operate these techniques as the real world evolves thanks to this system-of-systems complicated virtual simulation (e.g., more renewable sources, new diseases, population migrations or demographic changes). These simulations will assist teams of humans in responding to current events and solving an issue utilizing monthly, weekly, or day-ahead planning, in addition to long-term planning. AI will then be used to learn from the outcome and enhance the response during the next event.

Conclusion

Brands are utilizing a variety of cutting-edge technologies to fuel the Metaverse with the aim of making the virtual as real-time and authentic as possible. These technologies include AR, VR, Blockchain, AI, and IoT. Sensors, cameras, and wearables are already implemented and in use due to the present IoT development.

 The internet-based global digital landscape comprises a plethora of complex software and hardware systems spread on-premise and across the cloud. Also, there are software applications within embedded devices that are connected to the internet a la the Internet of Things (IoT). When we envision the future of the digital world, the IoT, along with other technologies, seems to be the harbinger. It has the potential to usher in a world driven by smart technologies to make lives more convenient and qualitatively superior. According to statistics, the number of IoT devices is likely to surpass 25.4 billion by 2030. Also, the IoT can generate an economic value ranging from $4 - $11 trillion by 2025 (Source: dataprot.net). The data shows how the Internet of Things (IoT) is going to define the digitized future of the world. 

However, notwithstanding the tremendous potential of IoT as a technology to drive the next digital revolution, it offers several challenges as well. IoT testing has become critical given that the success of the IoT ecosystem depends on the seamless functioning of its associated software and hardware systems. Let us discuss the challenges in some detail in the below-mentioned segment: 

Digitalization Challenges with IoT

The Internet of Things QA testing ensures IoT devices function safely and reliably. However, this type of testing has a host of challenges to grapple with, as mentioned below:

Testing in an omnichannel environment: The IoT ecosystem comprises various devices, platforms, and systems spread across on-premise and cloud environments. To ensure effective utilization of such systems, IoT testing should be conducted rigorously. Since IoT devices generate data at high velocity, their veracity needs to be ensured in real-time. However, this can be easier said than done, for the data generated is mostly unstructured. Also, IoT testing services need to test several devices with varying capabilities across platforms. Hence, creating a real IoT environment for testing can be a challenge, for there are many devices that require testing on the platform they operate upon. Besides, there are device upgrades in terms of software and firmware, which need to be considered by IoT device testing solutions for effective test outcomes. Thus, cross testing for IoT devices in an omnichannel environment comprising various versions and platforms can be an uphill task.

Cybersecurity risks: Given that IoT devices generate a large quantum of data (structured and unstructured), they may be vulnerable to hacking. Even so, statistics suggest that around seventy percent of IoT devices have security-related issues. Therefore, such devices should be subjected to rigorous IoT security testing. It involves identifying vulnerabilities in the architecture of devices using IoT penetration testing and fixing them. Testers should focus on checking and verifying the devices’ passwords and authorization policies.

Different protocols of IoT communications: IoT devices follow a range of protocols when it comes to communicating among themselves and with the server. These may include AMPQ, XMPP, CoAP, and MQTT. Besides, various components in an IoT ecosystem can use different protocols for communication. Hence, such components need to be tested over communication protocols to preclude functional and security risks. For instance, when embedded software within devices runs on low memory due to higher loading requests, they balance load requests among components using an IoT gateway. Testing IoT applications can verify the load balance among different components, thereby ensuring their smooth functioning.

Lack of standardization: Creating standards for IoT devices can be a challenge across four levels - application, business model, connectivity, and platform. The lack of a uniform standard across the IoT landscape makes it a difficult case for testers. This is because different companies build devices with competing and often conflicting standards. The common IoT testing approach is based on the intended use of the system or the use case. The best way to wriggle out of the situation is to establish uniform standardization across the above-mentioned levels.

Battery life: A large number of IoT devices are powered by batteries, which need to function at their optimum at all times. To ensure IoT devices are energy efficient, they need to have low-power components. Thus, the battery needs to be tested under different conditions and scenarios to maximize the life of such devices. Also, testers should check whether the device is able to report the low-battery status to the cloud platform properly.

Conclusion

The quality of an IoT ecosystem can only be ensured if the above-mentioned challenges are addressed by stringently testing IoT applications. Business enterprises building and utilizing IoT devices can look at various benefits by implementing stringent IoT testing. These include driving innovation and speeding up risk-free initiatives; facilitating time-to-market; improving interoperability; and achieving a higher ROI.

I remember when the Arduino Uno first came out circa 2005. Even though this 8-bit processor employs only a 16-MHz clock and offers only 32KB of Flash memory and 2KB of RAM, I still use these little rascals in a lot of my hobby projects to this day.

Of course, things have moved on since those days of yore. For example, one of the latest and greatest offerings from the folks at Arduino Pro is the Portenta X8.

maxncb-0408-01-arduino-portenta-x8-300x210.jpg?profile=RESIZE_400x

Portenta X8 (Click image to see a larger version — Image source: Arduino)

Oh, my goodness gracious me! Have you seen this little beauty, which is described as being an “Industrial-grade, secure system-on-module (SOM) with outstanding computational density”?

What we are talking about here is something that’s only around the size of a stick of chewing gum (66.04 x 25.40 mm) while boasting nine processor cores and coming pre-loaded with the Linux operating system (OS).

According to the web, it has a Cortex-A53 quad-core up to 1.8GHz per core + a Cortex-M4 up to 400MHz, along with a dual-core Cortex-M7 up to 480Mhz + another Cortex-M4 up to 240MHz.

Either I’m losing the ability to count, or the above adds up to only eight cores. Where’s the missing core?

Well, I am in a great position to learn the answer to this conundrum, because I’m going to be hosting a webinar on this little scamp — Arduino Portenta X8: Superpower Your Linux Applications with Real-Time Execution — tomorrow as I pen these words.

During this webinar, which will be presented by IoT Central, I will be chatting with Andrea Richetta, who is the Head of Customer Success at Arduino Pro, and who will be introducing the Portenta X8 and answering all of our questions.

This 1-hour webinar will commence at 10:00am USA Central Time (so that’s 8:00am Pacific Time and 11:00am Eastern Time). And, speaking of time, now would be a great time to register before all of the good seats are taken.

I’ll be the one in the Hawaiian shirt. Dare I hope to see you there? Register here.

The Internet of Things network of interconnected devices such as sensors, gateways, and computers that transfer the data over a wireless network eliminates the need for human intervention. IoT devices can be remotely tracked, and controlled in real-time. It also enables users to connect and interact with others over the internet. The applications of IoT are tremendous and it can be found in every part of human life, ranging from smartwatches to self-driving cars.

What Is IoT Device Management?

IoT device management refers to the ability to remotely accessing, monitoring, tracking and managing the functionality of IoT devices in order to ensure the deployed devices are secure, up to date and compliant. Here’s a breakdown of the reasons why businesses need an IoT device management platform:

  • Accelerate time to market

One of the biggest perks of the IoT device management platform is that it helps developers to reduce the time frame of product development and testing, thereby enabling them to release products to market on time. Furthermore, streamlining and automating network and device management tasks enables businesses to concentrate on their core competencies while lowering costs.

  • Secure device on and off boarding

A smart device is not, and should not be, automatically connected to an IoT network. A secure approach is required to configure and add only authorized devices to the network architecture, and a network and device management tool makes this simple and straightforward. End nodes can be authenticated and secure communications established via a web interface by registering and attaching them to the authorized base station using their network keys and identification credentials. Only after the node has completed the onboarding process it will be allowed to join the network and securely transmit data using network-level encryption. Similarly, if deployed nodes are no longer required, they can be easily offboarded from the web UI – without having to travel to the field.

  • Streamline network monitoring and troubleshooting

IoT device management platform enables firms to gain a top to bottom view of all registered nodes, network traffic and their status in a single interface. It acts as a central hub for data aggregation across base stations in a network with multiple base stations. This is especially useful for monitoring and identifying unexpected network and device problems. Businesses can quickly identify and determine the root causes of bottlenecks with real-time visibility into incoming data, battery level, and keep-alive messages from individual nodes. For example, if a node fails to deliver messages on a regular basis, the radio traffic may be overloaded. If, on the other hand, it completely disconnects from the network and stops sending messages, it could be due to a hardware or firmware flaw. Similarly, by continuously monitoring battery levels, firms can schedule maintenance for multiple devices at the same time, saving time and money.

  • Simplifies downstream application deployment

IoT device management platform serves as a link between the edge network, downstream data servers of users and enterprise applications. Using protocols like MQTT and API calls, a versatile IoT device management solution allows for easy integration with any backend system, whether on-premises or in the cloud. As a result, firms can easily deploy and scale IoT applications to meet changing business needs, whether by adding new devices to an existing app or connecting to a new analytics platform. It also enables businesses to gain a better view of all current integrations and applications from a single window thereby simplifying the management of an entire IoT project.

  • Eliminate security risks

Considering the ever-increasing complexity of cyber-attacks, it is critical to equip connected IoT network components such as base stations and routers with the most up-to-date security features. A manual approach cannot keep up with the demand for continuous and timely updates to these critical network infrastructures, particularly those deployed remotely - Here comes the need for an IoT device management tool. It will enable businesses to update operating systems automatically and run security updates from afar, helping them to save money while also ensuring their remote base stations are well-prepared against malicious attacks. Furthermore, round-the-clock monitoring of the network assists firms in the early detection of unusual patterns, such as an increase in data traffic, which could indicate a breach and eliminate security hazards.

Over the last few years, layers-3 switching has become quite popular. Though layer-3 switches are costlier than layer-2 or other traditional switches, layer-3 switches are way more beneficial for large companies.

Layer-3 switches not only solve the problems in large companies and networks but, also make IoT apps perform better. I have recently worked on an IOT project and for that project, we used layer-3 switches.

First of all, let's discuss layer-3 switches.

The layer-3 switches are a step ahead of the layer-2 switches. The smartness of these switches is their biggest advantage. When a company is facing a lot of traffic in their network then considering a layer-3 switch can be the right option. The only disadvantage of choosing a layer-3 switch is that they are complicated to set up and require a lot of time. Along with that, a layer-3 switch is costlier than the traditional switch. You need to be an expert in computer networking to configure this type of switch.

A layer-3 switch is a smart switch. Here with a smart switch, we mean that the switch has the ability to take a decision on its own. Instead of sending requests to all the systems connected to LAN, this switch sends requests to just a few systems that are connected to a specified network.

For example, a company network contains different departments like Sales, purchase, marketing, HR, testing, web development, and mobile app development. A layer-2 switch sends requests to all the networks while a layer-3 switch sends the request to just one network and the systems connected to that network. This switch determines for which network a request is sent with the help of the map. Once determined, it sends a request to just one network. This reduces the traffic on the network and increases speed.

Along with these advantages, with the help of the virtual-routing option one can change the hexadecimal number in the MAC address. With the help of this routing scheme, it is easier to convert hex to numbers easily. Hexadecimal to decimal number converter helps a person to read a MAC address in a better way easily.

Why did we use these switches in an IoT project?

We were developing an IoT project for a car garage. At this garage, there were more than 500 cars parked at any time. Our server used to receive more than 100 requests at the same time. Apart from that, the app was running on the Local area network along with the layer-2 switch. At that time, we assumed that the reason behind this might be the server and the switch were not able to handle these many requests at the same time. So, we insisted on the switches. Once they were replaced, our IoT app was working just fine.

So, this was our experience of working on an IOT app that used a layer-3 switch. If you have also worked on such an app then do share your experience here. It would be great for this community to know more about computer networking in detail.
