OFDM Forum Submits Fixed Wireless Access Standard


Working Group Participants Collaborate On IEEE 802.16.3 Submission

Calgary, Alberta
November 6, 2000

Following its meeting held in Tampa, FL last week, the OFDM Forum, an association organized to promote a single OFDM technology-based standard around the world, today announced that its Fixed Wireless Access Working Group has submitted a physical layer proposal using orthogonal frequency division multiplexing (OFDM) technology, which will be presented to the Institute of Electrical and Electronics Engineers (IEEE)'s 802.16.3 subcommittee at the IEEE's meetings later this week.

The proposal endorses using OFDM technology in the physical (PHY) layer of fixed wireless access systems below 11 GHz; the channel characteristics associated with these frequencies favor OFDM as it allows for very flexible deployments and high spectral efficiency. OFDM based systems using the bands below 11 GHz won't suffer from some of the restrictions of systems in the LMDS band, such as short link distances, line-of-site requirements and antenna limitations. Submission of this proposal by the OFDM Forum completes the first step in working with the IEEE to set a standard for fixed wireless systems below 11 GHz, a process that will likely take upwards of six months. 

"The submission prepared by the Fixed Wireless Access Working Group represents a significant milestone for the OFDM Forum," said Nico van Waes, Systems Engineer at Nokia and Chair of the OFDM Forum's Fixed Wireless Access Working Group. "By submitting this proposal, we have taken an important step towards interoperability and harmonized standards."

The proposal was prepared and is endorsed by representatives from the following companies:

* Alcatel
* Ericsson
* 4G Network Technologies
* Intersil
* IoWave Inc.
* Ishoni Networks Ltd.
* Motorola
* nBand Communications
* Nokia
* Pacific Broadband Communications
* Sasken Communication Technologies
(formerly Silicon Automation Systems) 
* Solectek Corporation
* SiWorks
* TIL-TEK Antennas
* Wi-LAN

By working together, these companies have demonstrated the importance of OFDM technology to the future of the high-speed wireless industry as well as the industry's commitment to establishing a standard that will enable reduced costs to implement, manufacture and sell wireless products for the consumer market. 

In addition to the Fixed Wireless Access group's submission, the OFDM Forum's November meeting saw the realization of significant milestones that both increase the organization's effectiveness and help it achieve its mandate. The Wireless Road Access Working Group has submitted an initial OFDM technology-based proposal to the Dedicated Short Range Communications (DSRC) committee for the broadband wireless distribution of real-time road safety, traffic management as well as a variety of commercial and private traveler services. 

The Wireless Road Access Working Group also expanded its existing charter to include broadband mobile networks, a segment that is seen to be in its infancy, following a vote by the organization's principal members. This group's new name will be the Broadband Mobile Wireless Working Group.

The OFDM Forum's Wireless LAN Working Group conducted a comprehensive review of Motorola and Radiata's recent proposal on OFDM-based HiperPANs for the IEEE's 5 GHz 802.15.3 standard and announced its support of the proposal.

In general OFDM Forum business, the organization established a special task force that will prepare a resolution for contribution, review and discussion at the next meeting to be held in February 2001. The resolution will look at 'Patent Disclosure and Willingness to License' among OFDM Forum members. 

The OFDM Forum has grown to include 46 members to date, 15 of which are listed as Principal Members of the organization. 

About OFDM:
Orthogonal Frequency Division Multiplexing (OFDM) is a technology that is considered to be the cornerstone of the next generation of high-speed wireless data products and services for corporate and consumer use. OFDM is also at the foundation of both the IEEE 802.11.a and ETSI BRAN HIPERLAN/2 standards and is used in numerous multimedia applications.

About the OFDM Forum:
The OFDM Forum is a market development association comprised of hardware manufacturers, software firms, telecommunications companies and other users interested in Orthogonal Frequency Division Multiplexing (OFDM) technology in wireless applications. Founded in December 1999, the OFDM Forum was established to develop a single, compatible global standard for cost-effective, high-speed wireless networks on a variety of devices. Founding companies are as follows: Ericsson, Nokia, Philips Semiconductors, Samsung Electro-Mechanics, Sony, Wi-LAN and the Testbed Center for Interoperability at the University of California at Santa Barbara (a division of CalTrans). The OFDM Forum has grown to include 46 members to date, 15 of which are listed as Principal Members of the organization. More information on the OFDM Forum can be found at
