For downlink synchronization in case of NB-IoT, the two LSB of the ARFCN is signalled in MIB for bands for which a 200 kHz channel raster is not supported, and the legacy 100 kHz raster is used.

An LTE operator can deploy NB-IoT inside an LTE carrier by allocating one of the Physical Resource Blocks (PRB) of 180 kHz to NB-IoT. As will become clear later in this article, the air interface of NB

The carrier for the initial connection setup is called Anchor carrier and the other carriers are called Non-Anchor carrier. When NB-IoT is operating in ''inband with the same PCI'' mode, only a specific PRB

This IoT platform stores uplink datagrams from the NB-IoT module. The customer server communicates with the IoT platform to retrieve uplink datagrams and to send downlink datagrams to the NB-IoT.

The device can wake up when it needs to send data, and is reachable for downlink for a brief time interval after each data transfer. Because the device remains registered in the network, it does not
