:: 2G/2.5G Defined
GSM for example is a 2G technology. It uses TDMA technology, proving data speeds of 9.6kbps/14.4kbps. The packet radio upgrade to GSM, called GPRS, can have speeds of up to 114kbps. GPRS an interim technology towards 3G, and hence is known as 2.5G. GSM might go the same way as the older first generation (1G) NMT and AMPS networks in 8-15 years because of the use of newer and better UMTS technology (More on GSM) ; (More on GPRS)
