Place in the wireless network
Cell sites are connected via copper facilities, optical fiber, or microwave. Whatever the connection, the next elements in the mobile telephone network are Base Station Controllers (BSCs) and Radio Network Controllers (RNCs). The base station controller is connected to a telephone switch, which is connected to the public switched telephone network (PSTN), while the Radio Network Controller handles 3G service, and is connected to Serving GPRS Support Node (SGSN), which is in turn connected to a data network, a telephone switch, or both.
