GSM (Global System for Mobile Communications: originally from Groupe Spcial Mobile) is the most popular standard for mobile telephony systems in the world.
General packet radio service (GPRS) is a packet oriented mobile data service available to users of the 2G cellular communication systems global system for mobile communications (GSM), as well as in the 3G systems. In 2G systems, GPRS provides data rates of 56-114 kbit/s.
Code division multiple access (CDMA) is a channel access method utilized by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply CDMA), which use CDMA as an underlying channel access method.

What are CDPD, CDMA, GSM, GPRS, iDEN, and TDMA data options? (#5668)
CDPD (Cellular Digital Packet Data) is a packet-based network that is typically isolated within major metro cities throughout North America. The CDPD network has an optimal bandwidth of 19.2K, and is run in the same spectrum as the AMPS networks.
**Verizon, AT&T Wireless, and I believe Cingular run CDPD networks**

CDMA (Code Division Multiple Access) can be either packet based or circuit based, depending on the method of access and version of the technology. cdmaOne (the version before CDMA2000) uses circuit switch data, that runs at 14.4, and acts as a dial-up connection. CDMA2000 is packet based, and has a maximum of 144kbps (for the currently deployed version in the US/Canada, which is 1xRTT), and delivers 50-120kbps in real world usage. Future CDMA2000 versions will provide a maximum of 384kbps (1xRTT rev. A), then 2.4mbps (1xEV-DO), and then 4.8mbps (1xEV-DV). It is capable of up to 56kbps for the dial-up ...more
