Unit 2 : common cellular system PPT
9 likes3,178 views
This document discusses the components of cellular network systems. It describes the major components as the subscriber device, base station subsystem (BSS), and network switching subsystem (NSS). The BSS consists of base transceiver stations (BTS) and base station controllers (BSC). The NSS includes the mobile switching center (MSC) and other registers. It also covers cellular component addressing using identifiers like MSISDN, IMSI, IMEI, and the process of call establishment and release in cellular networks.

- 14. Base Transceiver Station (BTS) • The BTS contains the RF components that provide the air interface for a particular cell . • Encodes, encrypts, multiplexes, modulates and feeds the RF signals to the antenna. • Communicates with Mobile station and BSC. • Consists of Transceivers (TRX) units. 14ASHUTHA K., ECE Dept., Sahyadri College of Engineering and Management
- 15. Base Station Controller (BSC) Provides the control for the BSS. Communicates directly with the MSC. May control single or multiple BTS. In charge of handoff , allocation of Radio channel to BTS and control of power level of BTS. During existing radio channel BSC maintains signal quality & disconnects when call is over. 15ASHUTHA K., ECE Dept., Sahyadri College of Engineering and Management
