1G established seamless mobileconnectivity introducing mobilevoice services

1G AMPS, NMT, TACS

2G;D-AMPS, GSM/GPRS,cdmaOne, EDGE2G digital wireless technologiesincreased voice capacity deliveringmobile to the masses. Those could do data but only as analog modem (using the whole channel) at 9.6Kbps2.5G added dedicated digital data (GPRS)2.75G faster data (EDGE)Data rates from 9.6Kbps (GSM) to to 33Kbps (GPRS) 200Kbps or higher(2.75G)

3G; CDMA2000/EV-DO,WCDMA/HSPA+, TD-SCDMA

3G optimized mobile for dataenabling mobile broadbandservices, and is evolving for fasterand better connectivityPeak speeds:384kbit/s for WCDMA7.2Mbit/sec for HSPA 21.6 Mbit/s for HSPA+

4G LTELTE, LTE Advanced4G LTE delivers more capacity forfaster and better mobilebroadband experiences, and is alsoexpanding in to new frontiersData speeds of LTEPeak download 100 Mbit/sPeak upload 50 Mbit/sData speeds of WiMAXPeak download 128 Mbit/sPeak upload 56 Mbit/s
