Dec 5, 2006, 2:43 PM by (staff)
The CDMA Development Group (CDG) today announced preliminary details of EV-DO Revision C, which uses additional technologies to squeeze even more data into a fixed amount of spectrum. The latest version of EV-DO will take advantage of every modern wireless technology and buzzword to pack spectrum with as much data as possible, including CDMA, TDM, OFDM, Multiple Input Multiple Output (MIMO) and Space Division Multiple Access (SDMA) advanced antenna techniques. The standard, which will be called Ultra Mobile Broadband, is capable of download speeds up to 280 Mpbs, although the CDG has not yet said how much spectrum will be required to reach such speeds. Revision B, announced just over a year ago is capable of download speeds up to 73.5 Mbps, but if an operator can dedicate 20 MHz of spectrum into a super channel. Ultra Mobile Broadband is expected to be finalized in early 2007 and commercially available in 2009. Revision B equipment and handsets are on track to be available in 2008.
