B103 (700 MHz)

Spanning globally and functioning in the 700 MHz spectrum, LTE Band 103 is exclusively carved out for Narrowband Internet of Things (NB-IoTNB-IoT: Narrowband IoT (NB-IoT) is a 3GPP Release 13 feature that reuses various principles and building blocks of the LTE physical layer and higher protocol layers and defines a new Cat-NB1 UE. The standard leverages a mobile operator's existing LTE base stations permitting rapid time-to…) applications. Sanctioned by 3GPP in Release 17.5, this 1 MHz-wide band caters to IoT devices that demand lower bandwidth but offer broader coverage and deeper penetration, especially in urban environments.
