CDG And 3GPP2 Published Ultra Mobile Broadband(UMB) Spec

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.

ITU to make WiMAX a 3G standard

According to the WiMAX Forum's white paper "WiMAX and IMT-2000" , there is a good chance that the International Telecommunication Union (ITU) will allow mobile WiMAX to be included in its range of 3G technologies, collectively known as IMT-2000.
Such a move would bring considerable benefits by allowing WiMAX to operate in globally allocated frequency bands, allow it to be used to complement other 3G technologies, enable global roaming and reduce equipment costs.

The White Paper says: "including IP-OFDMA (mobile WiMAX) within the IMT-2000 family of radio transmission technologies will put mobile WiMAX on a comparable worldwide footing with EV-DO, HSPA, and other recent and planned enhancements to 3G technology. This will offer operators an additional migration path to consider as they strive to add network capabilities to support a larger suite of value-added broadband services."

According to WiMAX Day, "The exact technology that is being considered for inclusion in IMT is 'IP-OFDMA'. This is an acronym for Internet Protocol - Orthogonal Frequency Division Multiple Access used by the IEEE 802.16e mobility standard, which is otherwise commonly referred to as WiMAX."
