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 ]
The aim is to address industrial applications, i.e. ultra-reliable, low-latency connectivity with negligible jitter for next-generation IoT. Compared to 802.15.7, the group decided to rewrite the standard entirely, based on existing and new contributions, to meet those targets.
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]
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
Nordic Semiconductor ASA (formerly known as Nordic VLSI) was founded in 1983 and is a Norwegian fabless technology company with its headquarters in Trondheim, Norway.The company specializes in designing ultra-low-power wireless communication semiconductors and supporting software for engineers developing and manufacturing Internet of Things (IoT) products.
Following the publication of the requirements the developers of radio access technologies such as 3GPP and ETSI are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies 5G NR, LTE-M and NB-IoT that together are expected to meet all requirements, [5] while ETSI is developing DECT-2020 NR ...

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.
