What is Narrowband IoT (NB-IoT)?
Narrowband Internet of Things (NB-IoT) is an LPWAN (Low Power Wide Area Network) radio technology standard developed by 3GPP to enable communication for a wide range of mobile devices and services, the specifications of which were frozen in 3GPP Release 13 (LTE Advanced Pro) in June 2016. Other 3GPP IoT technologies include eMTC (enhanced Machine-Type Communication) and EC-GSM-IoT.
NB-IoT uses a subset of the LTE standard, with a bandwidth of 200 kHz, and OFDM modulation for data download communications and SC-FDMA for data send communications.
