How to Manage the Approaching 2G/3G Sunset


Companies with cellular-based Internet of Things (IoT) devices are facing a major decision as cellular carriers begin to sunset their 2G and 3G networks in favor of 4G long-term evolution (LTE) technologies. This is not just happening in the U.S., but across the world. The transition will be especially challenging due to the complexities of a typical IoT end-to-end solution, which is often formed from several interlinked components with co-dependencies.


At first, many companies deploying IoT devices may have been doubtful about the necessity of a 4G LTE network, viewing it as having more benefit for consumer devices (such as mobile phones) that transmit large amounts of data. However, several new technologies such as LTE-M (also known as Cat-M1) and NB-IoT – which both operate on the 4G LTE networks – have been specifically designed for IoT devices. Known as cellular Low-Power Wide-Area (LPWA) technologies, they provide far greater coverage and capacity, while using much less power, ensuring long battery life.
