Other than WIMAX standard, CDMA2000 and WCDMA standards are aiming for high speed wireless connections as well. The CDMA Development Group has brought exciting news about the high speed (73Mbps download rate) CDMA2000 EV-DO Revision B standard, which will be available in 2008.
The CDMA Development Group, an industry organization promoting the CDMA (Code Division Multiple Access) cell phone standard, said Wednesday a new revision to the standard, which could lead to a big jump in cellular download rates in as little as two years, is on track to be published early next year.CDMA2000 EV-DO Revision B, as the revised standard is known, specifies a download speed, from the network to the terminal, of up to 73.5 Mbps (bits per second) and an upload speed of 27 Mbps, the group said in a statement issued to coincide with the 3G World Congress. The event opened on Monday in Hong Kong.
Carriers are expected to start deploying Revision A networks in early 2006 and Revision B networks in 2008, the group said.
The main competitor to the standard is WCDMA (Wideband Code Division Multiple Access), a 3G standard favored by many operators currently running GSM (Global System for Mobile Communications) networks. Most WCDMA networks currently support downloads of up to 384k bps but upgrades to the technology are planned. HSDPA (high speed downlink packet access) technology will enable downloads of between 10 Mbps and 20 Mbps and some carriers are planning to launch the system next year.
The 3GPP (3G Partnership Project), the group behind WCDMA, is also looking at a technology dubbed “Super 3G” that could offer download speeds of up to 100 Mbps as a stop-gap before 4G mobile systems begin appearing early in the next decade.
