Why Are NB-IoT and Cat-M Causing Disruptions?


Narrowband–Internet of Things (NB-IoT) and Category-M (CAT-M) are both next-gen technologies compared with LTE/4G. They have Massive Machine-Type Communication (mMTC) network connectivity standards. NB-IoT and Cat-M are similar because of their use in applications that do not require a low latency response within milliseconds—unlike real-time response applications that are served by ultrareliable low-latency communication network standards. A key function of some mMTC connectivity standards like NB-IoT is the ability to work deep indoors. NB-IoT also provides connectivity several meters underground. A differentiating factor of LTE for machines/Cat-M1 is that it can run on existing 4G/LTE network infrastructures as CAT-M is delivered by performing a series of software upgrades on the existing infrastructure of mobile network operators. While a key benefit of NB-IoT and CAT-M is their ability to preserve battery life—an improvement in comparison with Cat-1/LTE cellular technologies—NB-IoT has higher data throughput and improved latency compared with L…
