Which is the better low power LTE option, LTE-M or NB-IoT? The best answer is, it depends. LTE CAT-M1 supports higher data rates, and over-the-air updates. LTE CAT-M1 can be mobile, and is largely available. NB-IoT is best for stationary objects that will be sending small, infrequent messages. While both are great low power options, NB-IoT is typically lower than LTE-M.
