Base Transceiver Station (BTS) Foundation of Wireless Communication System

The hardware interface definition delineates the physical and electrical properties of the communications link for different hardware units in the communication equipment. As an example, in a base station, the interface between the BBU and the RRU specifies what type of cable is used, such as optical fiber, the pin-out configuration, the signaling protocol, as well as the power requirements. Standardized hardware interface definitions guarantee interoperability and linkage between separate manufacturers’ equipment so that parts can effortlessly be incorporated into one communication system from multiple vendors. This enhanced competition and offered more flexibility for operators when selecting components for their networks.
