The road from 2G and 3G to the next generation of IoT connectivity is not a straight line. Enterprises are navigating a mixed landscape of 4G LTE, LTE-M, NB-IoT, emerging 5G RedCap, and Non-Terrestrial Networks (NTN), each with different trade-offs in coverage, cost, power consumption, roaming, and long-term reliability.

This guide is designed for companies planning around 2G and 3G shutdowns and reassessing their connectivity choices for global IoT deployments. It reflects what the market has learned between 2021 and 2026, including why LTE Cat-1 and Cat-1 bis have become strong default options for many international fleets, where LTE-M and NB-IoT still fit, and why 5G RedCap remains a future consideration rather than a universal near-term replacement.

Key insights

🌫️ The Fog Has Cleared
The debate is no longer driven only by forecasts and assumptions. We now have years of real-world experience to learn from.

📶 The Safe Harbor is 4G
The safest long-term choice is not necessarily the technology that generated the most excitement a few years ago. For many global IoT deployments, the answer may already be here.

⚠️ The Sunset is a Swamp, Not a Cliff
Network shutdowns rarely happen all at once. Understanding what happens in between can make all the difference.

🚀 5G RedCap is a Future Story
The technology is promising, but timing matters. Is waiting for RedCap really the lowest-risk strategy?

🔧 The Hardware Sweet Spot
The right hardware choice can simplify much more than connectivity. It can shape manufacturing, provisioning, and lifecycle flexibility for years to come.
