Narrowband IoT (NB-IoT)
NB-IoT is a 3GPP low-power, wide-area technology for connecting large numbers of simple devices that send small amounts of data.
What is Narrowband IoT (NB-IoT)?
NB-IoT uses a very narrow slice of spectrum (180 kHz) and can run inside an LTE carrier, in its guard band or on its own. It reaches deep indoors and gives long battery life, at the cost of low data rates, which makes it suitable for meters, sensors and trackers.
