ULTRA MOBILE BROADBAND (UMB) SELECTED TO DESCRIBE NEXT MAJOR ADVANCEMENT IN MOBILE COMMUNICATIONS

CDG Selects Ultra Mobile Broadband (UMB) as the brand name for CDMA2000 1xEV-DO Revision C

HONG KONG — December 5, 2006 — The CDMA Development Group (CDG) (www.cdg.org) announced today that they have selected "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. The new standard is expected to be published early in the second quarter of 2007 and become commercially available on a global basis in early 2009.

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 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 an evolutionary upgrade within the family of CDMA2000 standards that can be deployed in existing or new spectrum allocations using scalable bandwidths up to 20 MHz.  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 techniques into a single global standard represents a major technological break-through within the mobile communications industry.

The IP-based, high-performance, ultra mobile broadband technology will be capable of ubiquitously and economically supporting a large variety of services that require extremely low latencies, low jitter and increased spectral efficiencies. As a result, the technology will be able to universally address a large cross-section of advanced mobile broadband services by delivering low rate, low latency, voice traffic at one end of the spectrum, just as efficiently as ultra-high-speed, latency insensitive, broadband data traffic at the other.

Due to its substantial performance advantage, evolutionary nature, spectrum flexibility, existing supplier base and time-to-market advantage, the technology is expected to leapfrog other wireless broadband technologies to become the leading standard adopted for next generation mobile telecommunications.
