The CDMA Development Group (CDG) and the Third Generation Partnership Project 2 (3GPP2) published the Ultra Mobile Broadband (UMB) air interface specification, which is often referred to as a 4G technology, in September.
The publication of this specification marks the world’s first IP-based mobile broadband standard to enable peak download data rates of 288 Mbps in a 20 MHz bandwidth, while preserving large economies of scope and scale. The spec claims that UMB is the first IP-based mobile broadband standard to enable peak download data rates of 288 Mbps in a 20 MHz bandwidth, while preserving large economies of scope and scale. UMB is the latest family member of CDMA2000 technologies and allows the transfer of native IP at speeds that are orders of magnitudes higher than technologies commercially available today, according to the standards groups. UMB is an Orthogonal Frequency Division Multiple Access (OFDMA) standard. UMB is expected to seamlessly integrate with CDMA2000 and EV-DO.
Here are a few of the specs:
* High-Speed Data: Peak download and upload speeds of 288 Mbps and 75 Mbps, respectively.
* Increased Data Capacity: Ability to deliver both high-capacity voice and broadband data events in mobile environments at excess of 300 km/hr.
* Low Latency: An average latency of 14.3 msec over-the-air with minimal jitter.
* Increased VoIP Capacity: Up to 1000 simultaneous VoIP users within a single sector.
