Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. [ 1 ] [ 2 ] The specification was frozen in 3GPP Release 13 ( LTE Advanced Pro ), in June 2016. [ 3 ]
NarrowBand IoT (NB-IoT), standardization effort by 3GPP for a LPWAN used in cellular networks. [14] Random phase multiple access (RPMA) from Ingenu, formerly known as On-Ramp Wireless, is based on a variation of CDMA technology for cellular phones, but uses unlicensed 2.4 GHz spectrum. [15] [16] RPMA is used in GE's AMI metering. [17]
From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, [1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.
Competing 3GPP IoT technologies include NB-IoT and EC-GSM-IoT. [5] The advantage of LTE-M over NB-IoT is its comparatively higher data rate, mobility, and voice over the network , but it requires more bandwidth, is more costly, and cannot be put into guard band portion of the frequency band for now.

NB-Fi Protocol is an open LPWAN protocol, which operates in unlicensed ISM radio band. Using the NB-Fi Protocol in devices allows data transmission range of up to 10 km in dense urban conditions, and up to 30 km in rural areas with up to 10 years on battery power.
