A base transceiver station (BTS) is a piece of equipment that facilitates wireless communication between user equipment and a network.The network can be that of any of the wireless communication technologies like GSM, CDMA, wireless local loop, Wi-Fi, Wi-MAX or other wide area network(WAN) technology.
BTS is also referred to as the radio base station (RBS), node B (in 3G Networks) or, simply, the base station (BS). For discussion of the standard the abbreviationfor evolved node B is widely used.
Though the term BTS can be applicable to any of the wireless communication standards, it is generally associated with mobile communication technologies like GSM and CDMA. A BTS forms part of the base station subsystem (BSS) developments for system management. It may also have equipment for encrypting and decrypting communications, spectrum filtering tools, etc. antennas may also be considered as components of BTS in general sense as they facilitate the functioning of BTS. Typically a BTS will have several transceivers which allow it to serve several different frequencies and different sectors of the cell. A BTS is controlled by a parent base station controller. The base station control function (BCF). The BCF is implemented as a discrete unit or even incorporated in a TRX in compact base stations. The BCF provides an operations and maintenance (O&M) connection to the network management system (NMS), and manages operational states of each TRX, as well assoftware handling and alarm collection. The basic structure and functions of the BTS remains the same regardless of the wireless
