The purpose of Wireless and Mobile Communication Systems are in four aspects: (1) The fundamental concepts of Personal Communications Services (PCS) architecture, (2) The protocols and management software that make it run, (3) The standards that are making it a universal solution, and (4) The mobile services that are changing the face of society as we know it. This course is divided into five distinct units. (1) PCS Network Management. This unit mainly describes (i) the basic technologies and systems of PCS, which include AMPS, GSM, DAMPS, IS-95 CDMA, and low-tier PCS systems, and (ii) the management procedures of handoff and roaming. (2) IS-41 Mobile System. This unit mainly describes (i) the protocol and system of IS-41 (ii) interconnection between IS-41 system and PSTN, (iii) the applications of IS-41, which are intersystem handoff and authentication, and (iv) the protocols and architecture of PACS and CDPD. (3) GSM Systems. This unit mainly describes the GSM system architecture, the location tracking, call setup procedure, security, and data services. This unit also describes the Voice over IP (VoIP) and the General Packet Radio Service (GPRS). (4) The wireless Internet. This unit mainly describes (i) the interconnection between the IS-41 and GSM systems, WAP, and the third generation mobile networks.
