CDMA Standards Group Chooses Ultra Mobile Broadband as Name For New Mobile CDMA Standard

December 8, 2006

The CDMA Development Group (CDG) announced this week they have chosen "Ultra Mobile Broadband" as the brand name to describe the advanced technologies and services that will be supported by the CDMA2000 1xEV-DO Revision C (Rev. C) standard.

Publication date for this new standard will be sometime in the second quarter of 2007. Devices and applications compliant with Ultra Mobile Broadband are expected to be widely available by early 2009.

The new standard supports mobile download speeds as 280 Mbps- viewed as ideal for the delivery of next generation services..

"With the ability to support peak download speeds as high as 280 Mbps in a mobile environment, Ultra Mobile Broadband (UMB) represents a major break-through in the delivery of next generation mobile broadband services," the CDG Group says.T"he technology will deliver packets of data at speeds that are orders of magnitude higher than what is currently available, and will do so within the entire cell edge coverage area."

UMB is actuallyan  upgrade within the family of CDMA2000 standards that can be deployed in existing or new spectrum allocations using scalable bandwidths up to 20 MHz. 

As the CDG explains:

"UMB enhances the performance and capabilities of CDMA2000 by combining the best aspects of the following leading air interface techniques; CDMA, TDM, OFDM, and OFDMA. UMB also incorporates Multiple Input Multiple Output (MIMO) and Space Division Multiple Access (SDMA) advanced antenna techniques to provide even greater capacity, coverage, and quality in deployments with multiple antennas.

"The sophisticated UMB control mechanisms use the above techniques to optimize the transmission of variable length packets for each application based upon the end-to-end system capabilities and the quality of service (QoS) requirements of each application and user. To support ubiquitous and universal access, UMB supports inter-technology hand-offs and seamless operation with existing CDMA2000 1X and 1xEV-DO systems. Integrating all of these advanced radio access."
