NarrowBand Internet of Things (NB-IoT)
Narrowband Internet of Things (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard developed by 3GPP to enable a wide range of cellular devices and services. which doesn’t operate in the licensed LTE construct. Instead, it works in one of three ways: Independently ; In unused 200-kHz bands that have previously been used for GSM (Global System for Mobile Communications) ; On LTE base stations allocating a resource block to NB-IoT operations or in their guard bands.
NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications. IoT applications which require more frequent communications will be better served by NB-IoT, which has no duty cycle limitations operating on the licensed spectrum.
Telecommunication giants such as Huawei, Ericsson, Qualcomm, and Vodafone have collectively put together this standard in conjunction with 3GPP. Huawei, Ericsson, and Qualcomm are interested in NB-IoT because it has a number of benefits.
