2.5G and 3G Wireless Networks

A new breed of wireless networks with higher speed and capacity than 2G that are being planned, designed and deployed in different countries now (2002).  These networks 
  • are in higher frequency band (2 GHz and beyond) with larger bandwidth (around 5 MHZ) than 2G
  • will provide higher speeds up to 2 Mbps in a fixed or stationary wireless environment and at 384 Kbps in a mobile environment. With this increased speed and capacity, these networks will support more voice subscribers and more bandwidth-intensive multi-media applications like MMS
  • hope to converge towards one international standard for 3G. This is unlikely to be fulfilled soon because of vendors' self interests, existing infrastructure dependencies and migration steps like 2.5G GSM/GPRS, 1xRTT CDMA, Edge, etc. before a common UMTS network becomes pervasive
