While GSM and TDMA operators around the world are going to deploy the technology defined earlier (GPRS - EDGE - WCDMA), CDMA operators are likely to choose another path. This is a consequence of different technology used in CDMA and its natural migration path towards high speed mobile networks capable of transferring packet-switched data. Most CDMA operators come from North America, but there are also countries using this technology in Asia. Globally, CDMA technology is substantially smaller than GSM in terms of subscriber base and a number of supporting operators. Geographically, however, it is important in the United States.

Sunday, February 22nd, 2009Wideband CDMA (WCDMA)
Sunday, February 22nd, 2009Wideband CDMA, being a part of the Universal Mobile Telecommunication System , is a third generation mobile network capable of transferring multimedia between terminals. Implementation cost for a mobile operator is high because the network has to be redesigned and new equipment is needed at the base stations. Additionally, consumers require new mobile terminals in order to access WCDMA services.
Enhanced Data Rates for Global Evolution (EDGE)
Sunday, February 22nd, 2009EDGE is another packet-switched evolution of the existing GSM networks. It boosts the bandwidth of GPRS networks up to 384 Kbit/s. This speed is achieved by using all eight 48 Kbit/s timeslots available in the network. Realistically, however, the speed mobile operators are able to offer to customers is likely to be around 40 Kbit/s upstream and 100 Kbit/s downstream. Even though EDGE depends on GPRS equipment to provide service, mobile operators may choose an option to update the existing GSM networks directly to EDGE. This way, the operator would have to wait a while. (more…)
Mobile Networks - General Packet Radio Service (GPRS)
Sunday, February 22nd, 2009GPRS is a packet-switched protocol offering instant Internet access and enhanced data capabilities to existing GSM networks. It requires a software upgrade, new cards in the base station, and two pieces of equipment to handle the Internet connection on the mobile operator’s side. Additionally, consumers require new mobile terminals in order to use the new services.
