NB-IoT, LTE-M and CAT-M1 are mobile GSMA standards and competitors for private, proprietary wireless IoT connectivity solutions such as SigFox and LoRaWAN.
GSMA standards, NB-IoT and LTE-M, offer low battery drain, longer radio range, and are 4G and 5G LTE (Long Term Evolution) compatible.
Of the GSMA LPWAN standards, NB-IoT is a low data standard that is suited to static devices in hard to reach or rural areas, that do not need to, or are unlikely to have the ability to switch radio masts.
LTE-M and CAT-M1 on the other hand both support mast handovers, and are therefore better suited to moving IoT devices, or those within reach of multiple masts such as moving vehicles or static devices in urban areas.
Proprietary standards such as LoRaWAN and SigFox also offer low battery drainage and longer range radio connectivity for IoT devices. They, however, require a private or collective network infrastructure to be in place and maintained.
