`
`WWiSE Consortium Submits Joint Proposal to the
`IEEE 802.11 Task Group N
`
`A consortium of companies collaborating under the moniker "WWiSE" today announced their
`intended submission of a complete joint proposal to the IEEE 802.11 Task Group N (TGn), which is
`chartered with developing a next-generation Wi-Fi standard capable of sustaining data throughput
`in excess of 100Mbps. The technology foundation is based on MIMO-OFDM. IEEE 802.11n will be
`an especially important standard in the WLAN market as it will build upon and extend the
`capabilities for the vast number of users currently enjoying the benefits of Wi-Fi connectivity.
`Companies within the WWiSE consortium that contributed to the proposal are Airgo Networks,
`Bermai, Broadcom, Conexant Systems, Inc., STMicroelectronics and Texas Instruments.
`
`"WWiSE" stands for worldwide spectrum efficiency, a key element for all proposals submitted to
`Task Group N. As such, the WWiSE proposal was developed with global deployment and
`backwards compatibility with all other Wi-Fi standards as its principal and mandatory requirements.
`Additional considerations included data-rate compliance with worldwide regulatory requirements in
`important regional markets such as Japan. The proposal also offers a royalty-free license option
`from the WWiSE companies. Such license options are designed to facilitate the worldwide
`deployment of 802.11n technology.
`
`The WWiSE proposal builds 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. Further, the coalition companies represent an important cross-section of both the IC

`supply and consumption segments that comprise the Wi-Fi marketplace, promoting a strong
`relationship between developers and end-product manufacturers.
`
`Highlights of the WWiSE Proposal
`The technical aspects of the WWiSE proposal mark a significant improvement in the capability of
`802.11 implementations. Key features include: Mandatory use of the approved, pre-existing,
`worldwide 20MHz Wi-Fi channel width, assuring immediate applicability and deployment in all
`regulatory jurisdictions.
`Enhanced MIMO-OFDM technology is key to achieving 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.
`Rates up to 540 Mbps, accomplished with a 4x4 MIMO structure and 40MHz channel width (where
`permissible by regulatory bodies), provide a roadmap for future devices and applications.
`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.
`Advanced forward-error-correction coding option to facilitate maximum coverage and range,
`applicable in all MIMO configurations and channel bandwidths.
`
`Intellectual Property (IP) Position of WWiSE Contributors
`The contributing member companies of WWiSE have jointly agreed to specific IP licensing terms
`for their proposal. Under IEEE requirements, all proposal submissions to TGn must be made under
`acceptance of RAND licensing (Reasonable and Non-Discriminatory) terms to all parties. WWiSE
`contributing companies fully comply with this requirement. In addition, if the WWiSE proposal is
`selected as the 802.11n standard, these companies have further agreed that reciprocal RAND-Z
`licenses (RAND under Zero royalty) to their essential IP will be available to any party upon request.
`
`Under this agreement, which is not a patent pool, but a reciprocal royalty-free individual license
`option, WWiSE member companies will not charge developers for an 802.11n license for their
`respective patent claims that are essential to implementing the standard. This will lower costs for
`developers, manufacturers and consumers. It is not necessary to be a contributor to the WWiSE
`proposal in order to take advantage of this license offer, which is expected to gain considerable
`support among the Wi-Fi product developer community.
`
`About IEEE 802.11
`The IEEE 802.11 specifications are wireless standards that specify an "over-the-air" interface
`between a wireless client and a base station or access point, as well as among wireless clients.
`Task groups within the 802.11 Working Group work on the specifications, seeking to develop the
`highest quality interoperable standards for wireless Internet. These specifications focus on
`improving service levels and resolving compatibility issues between manufacturers of wireless LAN
`equipment.
