A Base Station controller (BSC) is a telecommunication network component responsible for the control of one or more Base Transceiver Stations (BTS).

A base station is a radio receiver which may have one or multiple antenna. It was first used in mobile telecommunication networks.

Bandwidth is the maximum amount of data that can be transmitted over a network path in a fixed amount of time.

Backhaul in terms of telecommunication refers to the physical part of a network that is in between the backbone of the network and the individual local networks.
