UMTS as Third Generation T G (3G) wireless technology utilises a wide-band CDMA or TD/CDMA transceiver. Starting with channel bandwidths of 5 MHz it will offer data rates 2 Including voice or IP as a new trend. 3 In the USA – T1P1, in Japan – ARIB, in Korea – TTA and in China – CWTS. g. GSM. up to 2 Mbps. The introduction of UMTS with Release 1999 (R99) will use new spectrum and new radio network conﬁgurations while using the GSM core infrastructure. Although the circuit-switched enhancements such as HSCSD has increased transmission rates, it is packet-switched enhancements which will meet the challenges or demands posed on current wireless networks.
These requirements are primarily concerned with items such as quality of service, security and charging, service management, etc. 2 UMTS Terrestrial Radio-Access Aspects The UMTS Terrestrial Radio-Access (UTRA) system requirements are based on the service requirements.
