5g (5)

If I had to choose three reasons why the adoption of the IoT it´s delayed several years, one of the three would include would be the mistake in their strategy, faith, IoT employee sales skills and poor investment in key industries by Mobile Network Operators (MNOs) in this business.

When I wrote more than 5 years ago my post “How to select your M2M/IoT Service Provider” I referenced several annual reports from analysts like Gartner and vendors like Ericsson or Cisco. All of them presented very optimistic predictions that unfortunately have not been fulfilled.

During this time Mobile Network Operators have adapted to the market crude reality of the market with sometimes erratic strategies. Despite this fact has not discouraged new entrants that have energized a market with again high growth expectations. Today Tier 1 and Tier 2 Mobile Network Operators are competing with many IoT Connectivity providers in all industries and use cases. The good news for these new entrants is that the MNOs have not known captivate their customers.

What do I think the MNOS are thinking now?

1-    The Technological Battle of LPWAN networks

I do not want to open in this article a debate on which LPWAN connectivity technology (5G, NB-IoT, LTE-M, LoRA, Sigfox, ….) is the best. Each of these technologies will likely play an important role in the IoT space depending on the use case, so understanding the features and differences of each is critical.

You must not forget other IoT connectivity technologies (Satellite, Mesh networks, WiFi, Zigbee,..). I have always championed the idea of multiple IoT network coexistence in which objects will connect to provide an IoT service or be part of an aggregated IoT service. And those services can be provided by both licensed and unlicensed cellular networks. Let's assume that we will not have a single protocol that regulates all of them in a long time. We are also not going to ask manufacturers of objects to incorporate the different connectivity possibilities in their designs for obvious reasons of cost and battery life. What would be very valuable is that all IoT devices could add a unique identifier that allow will be part of a SuperIoTNet that works like the current internet. But now is future fiction.

2-    The Connectivity Services Offering 

Ideally we should try to find in our IoT Connectivity Service Provider offering something like Telefonica, an end-to-end complete commercial IoT connectivity offer that allow design and build a tailored secure IoT solution. But this in not gold all that glitters. We must evaluate the ability of these IoT Connectivity Service Providers to make easy the adoption of IoT in Small and Medium Business (SMBs) with pre-integrated industry solutions based on a rich ecosystem.

Customers wants to receive specialised advice to solve any IoT need at a one-stop-shop, including full stack technology solutions from hardware selection to middleware, application development and SaaS operations. Not many IoT Connectivity Providers have the internal resources to provide these services, in that cases customers should involve either or a partner or better an independent consultant as myself.

For some customers an offering like “IoT connectivity as a Service” provided by Arkessa can be an advantage, for others “The 1NCE IoT Flat Rate”, an all-inclusive connectivity package that comprises all elements and features that IoT customer need while having their assets connected is more important. For experienced M2M customers, the portfolio Kore Wireless and industry specialization is attractive. Eseye for instances solve your IoT challenges from device to AWS cloud. In Europe SMBs must consider in the short list Wireless Logic with 4 million devices connected to its platforms globally. Special mention to module companies like Sierra Wireless that offers a Connectivity and Device Management service that connects to 600+ partner networks around the globe with multiple redundant routes in every country to eliminate local coverage gaps or Telit which  Connectivity Service allow companies Monitor, Manage & Monetize their assets.

I am expecting the unlimited opportunities with the Internet of Things after the announcement a few days ago by DT Deutsche Telekom to spin out IoT unit and launch a global open ‘hub.’  More info about new DT IoT offering here: “From vertical to horizontal and back to vertical: our way to the new horizon”

Sorry, I can not extend this paragraph with more companies, but in the picture there are many other companies with attractive services that must be considered for your unique Business case.

3-    eSIM: Threat or Opportunity

The SIM card has also been evolving since its creation in 1991. From the size of a credit card it went to mini-SIM or the classic SIM that began to reduce in size, first to microSIM and then to nanoSIM and finally the embedded SIM (also called eSIM or eUICC or MMF2 UICC).

Presented in the preludes of the Mobile World Congress 2016, the eSIM is still a SIM but it will be embedded in the devices, without the possibility of withdrawing it. eSIM is a global specification by the GSMA which enables remote SIM provisioning of any mobile device. The eSIM is designed to remotely ​manage multiple mobile network operator subscriptions and be compliant​ with GSMA's Remote SIM Provisioning specifications​.  Install one eSIM during manufacturing and change the carrier on the fly.

To date, 200 mobile carriers in more than 80 countries offer eSIM consumer services. The embedded UICC is expected to reach over 200 million shipments in 2019 (source: Eurosmart, November 2019).

GSMA promises not to rig the eSIM standard in favour of its members.

eSIM now allows consumers to store multiple operator profiles on a device simultaneously, and switch between them remotely, though only one can be used at a time. The specification now extends to a wider range of devices. Manufacturers and operators can now enable consumers to select the operator of their choice and then securely download that operator’s SIM application to any device.

At first glance, building or supporting a global eSIM solution presents a major challenge (integration with other service providers and guarantee customer experience is expensive) and not appear to benefit Communication Service Providers. Looks like stupid to invest in a solution that make easier for customers to leave them. That´s why they have not done much to extend its use.

Why is good for IoT?.  UICC and eSIM technology gives enterprises control of IoT connectivity, simplifies international deployments of IoT devices and the transition to mobility services. Large scale international deployments are possible using a single factory installed SIM. The user subscription can be updated when the device is in the field.

ARM white paper introduces 7 top  Innovative eSIM use cases: Automotive, Shipping and Logistics, Object tracking and site monitoring, Smart Energy, Wearables, Agriculture, Home Security.

Choosing IoT Connectivity Service Providers

Choosing the right IoT Connectivity Service provider is not as easy as many can think. You can make a preselection using the lasts Gartner Magic Quadrant, also explore the local cellular Operators that have deployed a NB-IoT or LTE-M network and finally analyze other operators that maybe you never heard about them as I did.

The selection of the right IoT Connectivity Service Provider is a strategic decision for any Digital Transformation initiative, especially in enterprises adopting new resilient business models and optimizations of business processes. Some criteria you must consider selecting  your IoT CSP are:

  • Your internal capabilities
  • The offering: IoT Connectivity Services / IoT Managed Connectivity Services / IoT Connectivity Security Service / eSim Services
  • The cost of the IoT Connectivity Services and the flexibility of the tariffs
  • The type of IoT networks they have deployed and the coverage
  • The alliances with other IoT Connectivity Service Providers for global deployments
  • The types of M2M/IoT certified devices / modules and their applicability to your use cases.
  • The experience and references in your industry and vertical solution
  • The capabilities of their IoT Connectivity and Device Management Platforms
  • Open APIS for Integration with your Enterprise Systems
  • BSS/OSS systems and their applicability to your use
  • New business models eg IOTConnectivity as a Service
  • Levels of Support
  • Ecosystem of partners

Key Takeaways

It is not worth spending one minute more crying for the reasons that MNOs were unable to energize the IoT market earlier. We are where we are and the future is still bright, for those who really know how to see it.

The selection of the right IoT Connectivity Service Provider for your enterprise is a strategic decision. When my clients ask which is the best IoT Connectivity Service Provider? my first advice is: ". Let's define together your digital strategy, prioritize key uses cases, analyze new business model and your internal capabilities first and then work on the IoT Connectivity technology needed , which connectivity services comply with your requirements  and finally build a detailed business case that justify the value of your investment".

There is no best IoT connectivity Technology. It all depends on the use cases and the business model.

Interview: 5G, IoT and Hurricanes

Last week more than 21,000 visitors from 110 countries and territories attended the 2017 Mobile World Congress Americas in San Francisco. It was the first for MWC in the United States, having recently gone into a partnership with CTIA to up the appeal of the long-time wireless tradeshow. We were introduced to Advanced RF Technologies (ADRF) and discussed the the transition to 5G, IoT and hurricanes with ADRF Chief Operating Officer Arnold Kim. 

For our readers who are not familiar with your company, tell us about ADRF?

Advanced RF Technologies (ADRF) is a Top 5 Distributed Antenna System (DAS) provider. We've been operating for more than 18 years and provide in-building wireless connectivity solutions to improve cellular signal and data speeds when there is either a lot of people in one area, or the building infrastructure doesn't allow frequencies to enter unobstructed from the macro network. Our products include DAS, small cells, antennas and passive components.

What industries are adopting your technology?

Every industry needs better connectivity inside of their buildings, so we have clients from many different verticals. We work with all four major carriers (Sprint, Verizon, AT&T, T-Mobile) and our products are currently in most of the Fortune 100 company buildings, many high profile sports stadiums, commercial real estate, healthcare, and more. We also do plenty of Public Safety installations. 

Device types continue to proliferate - no longer is it a type of mobile phone. How do you advise customers on what types of frequencies and standards to implement?

Most companies have an understanding of what their connectivity needs are. However our approach is to offer flexible and future-proof solutions that will grow with our clients. We try to ensure that our clients will never need to do a full refresh on their investment.

From a connectivity perspective, what are some of the near term challenges for IoT?

The biggest challenges we see regarding the IoT has to do with the sheer volume of devices taking a bandwidth on a network. If you think about a sports stadium and trying to connect 50,000 people, network density quickly becomes a challenge. For large enterprises the number of devices connected and the challenges can be just as large. There's a wide range of devices that will be connected that don't necessarily need a 5G connection. For instance, a connected oil pipe simply needs to send signal that things are working correctly or not. This can be accomplished using a 3G signal, on a low frequency band (which travels more effectively that a 5G signal on a high band might). In areas where the is limited connectivity, this is an important thing to consider.

It’s still early days, but how are you tackling the transition from 4G to 5G?

While the definition of 5G has yet to be settled, we are prepared for it, and those who have our systems in place will be too. Our new ADX V series DAS is modular and works with every type of frequency. When 5G becomes standard, whatever frequency may be adopted by each carrier to run the signal will be compatible with our equipment. At MWC America, we are announcing new Head End and Remote Modules for ADX V to support 600 MHz, the frequency that T-mobile plans to use exclusively for 5G. Not many DAS solutions today support it.

Let’s turn our attention to current events. Hurricane Harvey and the floods it caused in Houston. What role does ADRF play in public safety and how do you support response teams when critical infrastructure comes down?

ADRF performs a lot of public safety installations and we were one of the first companies to be FirstNet compliant. As an example, we recently installed two public safety DAS in the new Atlanta Braves stadium. Dense areas and public venues are mostly required by law to have complete, uninterrupted connection at all times. We provide the systems that allow for that. We have also introduced a series of mobile repeaters that can be implemented in crisis situations as well as outdoor venues where concerts are taking place.

Another example is Hurricane Sandy, a Category 3 major hurricane which affected coastal Mid-Atlantic states in 2012.Verizon deployed CROW (Cellular Repeater on Wheels) help provide interim emergency communications. CROWs are low cost, portable, over the air (which doesn’t requires backhaul) and can be used to provide expanded cellular network coverage or capacity. 

What's the most interesting implementation you've done? Why?

We were selected to make the happiest place on earth one of the best connected. Around Disney World parks, we put in a series of repeaters to provide better coverage and let families share their adventures. One of the important parts of the installation, especially in crowded venues where aesthetic is of the utmost importance, is to make sure equipment is concealed and hidden. Locating those areas when thousands of people are walking the entirety of the park every single day was a challenge.

Anything else you’d like to add?

We announced a new high power outdoor modular repeater at Mobile World Congress Americas, and while it’s intended purpose is to improve cellular connection in outdoor areas, it will be beneficial for IoT connectivity as more people become reliant on having these connections everywhere. Our products support every frequency including those that will be used for 5G, and the 3G and 4G that powers IoT connections. The importance of having blanket coverage for IoT cannot be understated, especially as more important devices become connected in the future.

5G Internet of Things

By Anand R. Prasad. This article originally appeared here.

This is first part of the article based on several talks I have given on 5G security since last year. In this part I present my views about 5G. On purpose I have avoided discussion on various activities regarding 5G around the globe (3GPP, ITU etc.). 

5G is expected to bring several changes in mobile communications system but watch that these changes are not something that will happen couple of years down the road instead they are already happening. First flavor of 5G is expected to be available in 2018 with the complete solution available in the market by 2020. With digitization on its way to touch every part of life, Internet of Things (IOT) will be integral part of 5G from the very beginning; this is unlike 4G where IOT came later.

In the following we will go through some of the key changes 5G is expected to bring. In the next article I will discuss security aspects.

(Core) Network

As we move ahead, virtualization technology (network function virtualization or NFV) and software defined network (SDN) for mobile core networks will become mature and actually bring down the cost while achieving the quality requirement. This will lead to the network (core network) being increasingly built of off-the-shelf hardware and open source software, virtualization will become common and cloud based mobile network will become available. It is expected that the network should accommodate multiple radio technologies. 

Changes mentioned above (virtualization and cloud) will allow networks to be launched for a specific service, a concept now being termed as network slicing or just slicing - this is what I call as vertical network that fulfill specific requirements in contrast to horizontal networks today that cater for all services. Virtualization and cloud also means that the network will become more open and accessible that will lead to network border going deeper in the network, i.e. instead of network elements as end-point a software module in the server farm will be the end-point and this end-point can migrate to different locations.

Radio Access Technology

Radio access technology will see several improvements with data-rates available from few bits going up to several gigabits, delays going down to micro- if not nano-seconds (compare it with millisecond range in today’s system). Radio access network will also become partially virtualized and cloud based.

Spectrum

Spectrum used for 5G will be different, there have been discussions of higher GHz bands, and thus the radio characteristics will be very different as well. The spectrum will have implications on coverage and behavior of radio access technology.

With the arrival of 5G, we should also expect wider usage of cognitive radio in mobile networks and aggregation with unlicensed band as well as usage of unlicensed band technologies.

Security Credentials

Given the variety of scenarios and technologies expected to come in use for 5G, it is worth questioning whether the security credentials should stay the same as today and whether there will be change in technology for storage of credentials. Change in security credentials could have implications on authentication and other security mechanisms.

Storage of security credentials can be seen from both network and device side. From the network side the storage is in terms of location, whether the security credentials are stored at the mobile network domain or at partner domain. Implication is the change in authentication end-point and transfer of session related security credentials to appropriate network functions after completion of authentication.

With regard to security credential storage in devices one can consider three different forms of storage (1) secure hardware environment as we have today in the form of UICC that is commonly known as SIM card, (2) embedded secure hardware environment, e.g. a UICC or similar device is implemented in a modem, this brings us to something like embedded SIM and (3) some form of software.

End Devices

End devices will see huge transformation together with technology enhancements that we are seeing around us. Already with the arrival of 4G we have seen increased usage of smartphone and over the top (OTT) services. As we move towards 5G we will see increased number of smart “devices” as well as a whole variety of IOT devices associated to a plethora of services, there will be wearables in common use and also virtual or augmented reality (VR or AR) type devices commonly available. Open source devices are available since a while now; we should expect increased usage of such devices as we move towards 5G.

With 5G we should expect mobile devices (all types like smart devices, IOT, VR, AR) to be reachable over Internet Protocol (IP) addresses, i.e. they will be directly connected to the Internet. On the other end of the spectrum there will be devices requiring long battery life (say 10 years) that are expected to work at very low data rates. 

Services

Services for VR, AR, IOT, smart devices and many more will appear as 5G will provision a platform that can fulfill variety of requirements. These services will be provisioned by the mobile operator or by a third party with or without business relation with the mobile operator.

Over the top (OTT) services are already there that have the potential of leading to potential cyber-attacks through malware, phishing etc. Sponsored data should be a source of revenue for mobile operators but misuse here leads to operator making financial loss.

Business

We are already seeing change in business model of mobile operators. One such change is in the form of APIs being made available for third parties to launch services over the mobile network. 

With 5G in picture we will also see operators getting in partnership with other companies to provision the services. This would mean that the partners would own the subscribers while the operator would be responsible for correct usage of the licensed spectrum.

User Space

5G will have much deeper penetration in the society than any of the technologies to-date. This equates to technology being used by savvy users like millennials and also Information and Communication Technology (ICT) illiterates who will leap-frog directly to the new technology. Thus the technology will go to the deepest part of life; not just human beings but animals (e.g. for vital information) and plants (e.g. for watering) will also get connected with IOT.
