Evolution Toward Third Generation Wireless Networks

James J. Steinbugl


The explosive growth of the Internet is expected to produce a tremendous increase in the demand for wireless multimedia services. First and second generation wireless networks have proven capable of providing voice and low-rate data services; however, their current air interfaces are inadequate for satisfying the higher data rates that have been specified by the ITU for IMT-2000. In order to satisfy so-called third generation requirements, GSM networks will evolve to GPRS/EDGE technology and ultimately utilize a new air interface based on wideband CDMA. IS-136 networks will migrate to 136+ and later provide higher data rates through 136HS. Finally, cdma2000 will provide the migration path for existing IS-95 networks based on code division multiple access.
