Industry Support Surges for WWiSE's Straightforward Approach for Next Generation Wi-Fi Standard
DALLAS, Feb. 24 -- The World Wide Spectrum Efficiency (WWiSE)
consortium, a group of 12 companies which developed a complete proposal for
the IEEE 802.11 Task Group N (TGn), today announced a merger of technical
proposals with Motorola, Inc. Motorola had previously developed a separate
proposal but will now work as part of the WWiSE consortium on an enhanced
proposal that will be submitted to the IEEE 802.11 TGn for consideration. TGn
is chartered with developing a next-generation Wi-Fi standard capable of
sustaining data throughput in excess of 100Mbps. The other members of the
WWiSE consortium are Airgo Networks, Broadcom Corporation, Buffalo, Conexant
Systems, Inc., ETRI, Hughes Network Systems, Ralink Technology, Realtek,
STMicroelectronics, Texas Instruments (NYSE: TXN), TrellisWare Technologies
and Winbond Electronics.
"Motorola believes the IEEE 802.11n standard is an important building
block for offering connectivity to high bandwidth services in the home and
enterprise environment," said Miguel Pellon, vice president technology-
standards, Motorola, Inc. "We believe our experience in making applications
such as mobile VoIP and mobile multimedia streaming operate in handheld
devices and our expertise in power saving mechanisms strengthen the WWiSE
proposal for 802.11n."
The updated WWiSE proposal will continue to build on the existing and
globally adopted 20MHz channel format of the tens of millions of Wi-Fi devices
already in use. This approach ensures support for the existing worldwide
installed base, while improving the performance of Wi-Fi networks within the
designated RF spectrum. Motorola's contributions to the revised WWiSE
proposal will enhance the pre-existing specification by improving range, reach
and robustness for the various operating modes.
Highlights of the Enhanced WWiSE proposal
Key features of the combined WWiSE proposal include:
1. Mandatory use of the approved, pre-existing, worldwide 20MHz Wi-Fi
channel width, assuring immediate applicability and deployment in all
regulatory jurisdictions.
2. Enhanced MIMO technology that enables a maximum data rate of 135 Mbps
in the minimum mandatory 2x2 configuration and a single 20MHz channel
to keep implementation costs low, while greatly improving upon simple
antenna additions or channel bonding schemes.
3. Mandatory modes affording backwards compatibility and
interoperability with existing Wi-Fi devices in the 5 GHz and 2.4 GHz
bands to ensure strong support of legacy deployments.
4. Enhancements that improve robustness and range for all modes of
operations and data rates.
5. Modes of operation specifically intended for mobile, battery-powered
applications and devices such as handsets and cell phones.
6. Advanced forward-error-correction coding option to facilitate maximum
coverage and range, applicable in all MIMO configurations and channel
bandwidths.
7. Rates up to 540 Mbps, accomplished with a 4x4 MIMO structure and
optional 40MHz channel width (where permissible by regulatory
bodies), provide a clear and extensible roadmap for future devices
and applications.
8. Provisions for advanced features that improve data rate and range
such as beam-forming and closed loop methods.
"Motorola's joining with WWiSE is a strong endorsement of the fundamental
technical direction adopted by WWiSE to improve spectral efficiency and
improve range and robustness. Their contributions enrich the proposal in a
manner consistent with these objectives," said Jim Zyren, WWiSE spokesperson
and director of marketing, wireless networking business unit, Conexant
Systems, Inc. "The updated WWiSE proposal is now in a state that can be
quickly adopted as the baseline draft standard for 802.11n."
Next Steps
The WWiSE proposal is one of two remaining proposals set to be considered
by IEEE 802.11 Task Group N at its next meeting during the week of March 14 in
Atlanta, GA. At this session, one proposal could be selected as the baseline
for the new standard. With momentum growing for the WWiSE proposal, more
companies are soon expected to join the effort and help support its acceptance
at upcoming meetings.
WWiSE has recently updated its Intellectual Property offer for essential
patents embodied in the WWiSE proposal. It remains fully consistent with IEEE
requirements known as RAND (Reasonable and Non-Discriminatory). WWiSE
companies will offer their essential IP under RAND terms, the basic
requirement for anyone wishing to participate in IEEE standards setting
processes. Likewise, any company may join and support WWiSE so long as they
adhere to the IEEE IP rights policies and procedures. Further information
