The next time you buy a mobile device or pick a mobile carrier, here's a handy guide to the alphabet soup of cellular technologies and what generation they belong to:
2G: GSM, CDMA, TDMA
2.5G: GPRS, EDGE, CMDA2000 1xRTT
3G: UMTS, W-CDMA, CDMA2000 EV-DO, TD-SCDMA
3.5G: HSDPA, HSUPA, HSPA+, Flash-OFDM, WiMax (IEEE 802.16d and 802.16e versions now being deployed), LTE (the first 3GPP version now being deployed)
4G: WiMax Release 2 (IEEE 802.16m), WirelessMAN Advanced, LTE Advanced, MBWA (IEEE 802.20) -- none of these is ready for commercial deployment, by the way
Don't let the carriers say otherwise. |
