Base Transceiver Station

What is it? 

A base transceiver station (BTS), also known as a radio base station (RBS) or node B (eNB), is a fixed radio transceiver that links mobile devices to a mobile network. 

How does it work? 

BTSs contain equipment for the encryption and decryption of communications, spectrum filtering equipment antennas that relay radio messages, duplexers, amplifiers, and multiple transceivers (TRX) to serve different frequencies and sectors.  

It gives out to and receives radio signals from mobile devices. After that, it converts these radio signals into digital signals and passes them to the network to route to other terminals or the Internet. 

The parent base station controller (BSC) handles all BTSs due to the base station control function (BCF). I may either be a separate unit or integrate with the TRX. The BCF ensures connection to the network management system (NMS) and controls the transceiver’s operational states.
