Narrowband-IoT is the name of the standard that the 3GPP have developed. It operates on Band 8 and 20, which is 880-960MHz and 791-832KHz. This means devices transmitting small packets of data can connect using existing LTE network infrastructures – and some of the biggest carriers in the world plan on deploying the technology imminently, in one of three ways: 2020-04-17 Moreover, the allocation of frequency band for NB-IoT within LTE band, or as a standalone, might not be synchronous in all the cells, resulting in intercell interference (ICI) from the NB-IoT has been designed to offer extended coverage compared to traditional networks through the use of an ultra-narrow bandwidth of only 180 kHz.
