Cellular Backhaul and ATM Transport
Overview
The second generation of cellular services (2G), as characterized by the GSM/CDMA/TDMA standard, is a TDM-based technology. The main applications, switched voice services and simple messaging services, run over PDH/SDH access networks, relying on a wide variety of wireline and wireless transport solutions. The relatively new 2.5G (GPRS) data service is still very much a TDM-based technology, providing an interim solution until wideband 3G services take hold.
The aim of the emerging third cellular generation, characterized by the UMTS/CDMA2000 (or W-CDMA) standard, is to provide a wireless and mobile means to support wideband voice and data services, such as multimedia applications, interactive Internet surfing and videoconferencing. This third generation of mobile technology is expected to provide up to 2 Mbps (384 kbps of net bandwidth to the user) of wireless service to each subscriber. A substantial leap from 64 kbps GSM/CDMA/TDMA bandwidth, 3G requires a broadband transport technology solution based on a cell- or packet-switched access network.
