The Future of Cellular IoT Explained – LTE M1, LTE NB-IoT, eSIM, and Battery Life Hype

Telecom companies also want their share of the IoT business, but with 2G to 4G cellular technology often being too power hungry and/or expensive for this market, 2G on-going – or upcoming – sunset depending on your location, LTE Cat M1 and LTE Cat NB1 (aka NB-IoT) standards have been developed, and used in products like Pycom FiPy board, and SARA-R4 and SARA-M2 modules. If you want to have an overview learn about the new LTE IoT standards and the future of cellular IoT, Particle has published a useful presentation – embedded below – dealing with both, as well as eSIM (Embedded SIM), 2G sunset, and battery life expectations. The main takeaways from my reading of the presentation: LTE NB1 is better suited for low power stationary sensors transmitting a small amount of data a few times a day. Requires new hardware and software LTE M1 can be used for […]
