The CDMA Development Group (CDG) and the Third Generation Partnership Project 2 (3GPP2) published the Ultra Mobile Broadband (UMB) air interface specification - 3GPP2 C.S0084-0 version 2.0.
The UMB specification is expected to be converted into a global standard by the 3GPP2 organizational partners, which include the Association of Radio Industries and Businesses (ARIB) in Japan, China Communications Standards Association (CCSA), Telecommunications Industry Association (TIA), Telecommunications Technology Association (TTA) in Korea and the Telecommunications Technology Committee (TTC) in Japan, according to the CDG.
This specification is touted as being one of the first Internet Protocol (IP)-based mobile broadband standards to enable peak download data rates of 288 Mbps in a 20 MHz bandwidth, said the CDG.
UMB represents next generation mobile broadband services by enabling the transfer of native IP, variable length, data packets at speeds that are higher than what is commercially available today, said the CDG.
UMB is an Orthogonal Frequency Division Multiple Access (OFDMA) solution that uses control and signaling mechanisms, radio resource management (RRM), adaptive reverse link (RL) interference management and antenna techniques such as multiple-input multiple-output (MIMO), space-division multiple access (SDMA) and beamforming.
The UMB solution is designed to address a cross section of mobile broadband services by delivering low-rate, low latency voice traffic at one end of the spectrum as efficiently as ultra-high-speed, latency insensitive, broadband data traffic at the other, according to the CDG.
To support ubiquitous and universal access, UMB supports inter-technology hand offs and operation with existing CDMA2000 1x and 1x evolution-data optimized (EV-DO) systems.
The UMB solution delivers:
- High-speed data: Peak download and upload speeds of 288 Mbps and 75 Mbps, respectively, in a mobile environment with a 20 MHz bandwidth.
- Increased data capacity: Ability to deliver both high-capacity voice and broadband data in all environments; fixed, pedestrian and mobile in excess of 300 km/hr.
- Low latency: An average latency of 14.3 msec over-the-air to support Voice over IP (VoIP), push-to-talk and other applications with minimal jitter.
- Increased VoIP capacity: Up to 1,000 simultaneous VoIP users within a single sector, 20 MHz of bandwidth in a mobile environment without degrading concurrent data throughput capacity.
- Large coverage: Large wide area network (WAN) coverage areas equivalent to existing cellular networks; with either ubiquitous coverage for roaming or noncontiguous coverage for hot zone applications.
- Full mobility: Mobility support with hand offs inherent in all aspects of the UMB design.
- Converged Access Network (CAN): Supports the deployment of a CAN, which is an advanced IP-based Radio Access Network (RAN) architecture being developed by 3GPP2 to support multiple access technologies and network capabilities such as quality-of-service (QoS) with fewer network nodes and lower latencies.
- Multicasting: Support for high-speed multicast of multimedia content.
- Deployment flexibility: Deployable in flexible bandwidth allocations between 1.25 MHz and 20 MHz using incremental channel bandwidths allocations of around 150 kHz within the 450 MHz, 700 MHz, 850 MHz, 1700 MHz, 1900 MHz, 1700/2100 MHz (advanced wireless services), 1900/2100 MHz (International Mobile Communications) and 2500 MHz (3G extension) spectrum bands. The IP-based UMB radio access network is also designed to interoperate with legacy circuit-switched networks.
- Device availability: Multimode, multiband UMB devices are designed to leverage the existing 3G code division multiple access (CDMA) device selection.
- Strong ecosystem: UMB leverages the existing ecosystem of 3G CDMA clients and suppliers.
- Time-to-market: UMB is expected to become commercially available on a global basis in 2009.
