Nortel Outlines CDMA 1xEV-DO Revision A Strategy

Nortel outlined plans to offer CDMA2000 1xEV-DO (evolution data optimized) Revision A (DO Rev A) technology to CDMA operators. The company also disclosed that it is planning live market trials with Verizon Wireless beginning in 2006. Nortel currently supplies EV-DO to 11 out of the 17 operators that have commercially launched across the globe.


The DO Rev A technology delivers peak data rate bursts up to 3.1 Mbps (on the forward link and up to 1.8 Mbps on the reverse link. DO Rev A operates in the 1.25 MHz channel and is optimized for packet data service. DO Rev A has been approved by the 3GPP2 Technical Specification Group (TSG-C).


Nortel said the technology provides one of the lowest costs per bit when compared to other cellular technologies. The company noted that it has been a major contributor to the development of 1xEV-DO Rev. 0 and Rev. A standards in 3GPP2. Nortel has proposed key concepts to the standards that improve packing efficiency for High Rate Packet Data (HRPD) Air interface. Nortel was also instrumental in providing leadership in the development process of 1xEV-DO Revision A physical layer.
