In telecommunications, a base station is a fixed transceiver that is the main communication point for one or more wireless mobile client devices. It further connects the device to other. A communication base station is composed of a computer room, base station, antenna, feeder line (transmission line between transmitter and antenna), and supporting equipment. The antenna is at the top of the signal tower, and below the tower is a computer room. Along with increased capacity demands driven by the explosion of cloud and connected device growth, engineers need interconnects that enhance the design. A base transceiver station (BTS) or a baseband unit (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network.
