UMB Spec Published

COSTA MESA, Calif. -- The CDMADevelopment Group (CDG) (www.cdg.org) and the Third GenerationPartnership Project 2 (3GPP2) (www.3GPP2.org) announced today thepublication of the Ultra Mobile Broadband(tm) (UMB(tm)) air interfacespecification -- 3GPP2 C.S0084-0 v2.0. It is expected that the UMBspecification will be quickly converted into an official globalstandard by the 3GPP2 organizational partners, which include theAssociation of Radio Industries and Businesses (ARIB) in Japan, ChinaCommunications Standards Association (CCSA), TelecommunicationsIndustry Association (TIA) in North America, TelecommunicationsTechnology Association (TTA) in Korea, and the TelecommunicationsTechnology Committee (TTC) in Japan. TIA plans to designate the UMBstandard as TIA-1121. The publication of this specification marks theworld's first IP-based mobile broadband standard to enable peakdownload data rates of 288 Mbps in a 20 MHz bandwidth, while preservinglarge economies of scope and scale.

UMB represents a major break-through in next generation mobilebroadband services by enabling the transfer of native IP, variablelength, data packets at speeds that are orders of magnitude higher thanwhat is commercially available today. It is the latest member of thefamily of CDMA2000(r) standards that was designed from the ground up toimprove the overall end-user experience and strengthen an operator'searnings potential.

UMB is the leading Orthogonal Frequency Division Multiple Access(OFDMA) solution, using sophisticated control and signaling mechanisms,radio resource management (RRM), adaptive reverse link (RL)interference management, and advanced antenna techniques, such asMultiple Input Multiple Output (MIMO), Space Division Multiple Access(SDMA) and beamforming. The UMB solution universally addresses a largecross-section of advanced mobile broadband services by economicallydelivering low-rate, low latency voice traffic at one end of thespectrum, just as efficiently as ultra-high-speed, latency insensitive,broadband data traffic at the other. To support ubiquitous anduniversal access, UMB supports inter-technology hand-offs and seamlessoperation with existing CDMA2000 1X and 1xEV-DO systems.
