![]() It also includes the following functions −Įncoding, encrypting, multiplexing, modulating, and feeding the RF signals to the antenna Each BTS has between 1 and 16 transceivers, depending on the density of users in the cell. Its transmitting power defines the size of a cell. A BTS is usually placed in the center of a cell. The BTS corresponds to the transceivers and antennas used in each cell of the network. In a large urban area, a large number of BTSs may be deployed. The BTS houses the radio transceivers that define a cell and handles the radio link protocols with the MS. A separate high-speed line (T1 or E1) is then connected from the BSS to the Mobile MSC. The BSS uses the Abis interface between the BTS and the BSC. A BSS may have one or more base stations. The radio components of a BSS may consist of four to seven or nine cells. The BTS and the BSC communicate across the specified Abis interface, enabling operations between components that are made by different suppliers. You need to insert the SIM card into another GSM cellular phone to receive calls at that phone, make calls from that phone, or receive other subscribed services.

The MS also provides the receptor for SMS messages, enabling the user to toggle between the voice and data use. As such, other services are also provided, which include − ![]() It provides the air interface to the user in GSM networks. The MS consists of the physical equipment, such as the radio transceiver, display and digital signal processors, and the SIM card. The GSM network can be broadly divided into − These functions and interfaces are explained in this chapter.
