Public Land Mobile Networks (PLMN)
n Mobility is required practically for all services in the
very near future!
n In this course we will discuss especially the GSM (Global
System for Mobile communications) (9.6 kbit/s++) and
WCDMA (Wideband Code Division Multiple Access, or
UMTS) networks
n UMTS will be launched 2002-2003 yielding mobile data
rates up to 2 Mb/s. However, the GSM network will be
upgraded for higher rates thanks to
n GPRS (General Packet Switched Data),
n HSCSD (High Speed Circuit Switched Data) and
n EDGE (Enhanced Data Rates for GSM Evolution)
