Jim, my understanding is that the technology offered by Wi-Lan and CISCO increases the potential for MMDS. The details of the Distributed Wireless Call Processing patent are shown below. Please click on "View Images (12 pages)" to see the drawings. Regards, Phil ---------------------------------------------------------- patent.womplex.ibm.com ----------------------------------------------------------- Excerpt from WLGS SB-2/A dated May 18, 2000 Vector Orthogonal Frequency Division Multiplexing One major technical problem with MMDS has traditionally been a clear line of sight was necessary between the transmission and the receiver. This limitation allowed MMDS to be used only in areas with even terrain and no obstructions, insofar as buildings and hills would often disrupt MMDS transmissions. Although MMDS continues to experience line of sight limitations, there have been recent developments which have shown a potential for reducing these problems. Cisco Systems, Inc. has recently announced the development of -20- <PAGE> Vector Orthogonal Frequency Division Multiplexing, which purportedly has the ability to reassemble multi-path MMDS signals at the receiving point so that they appear to arrive in a single stream from one location, even if obstacles are in the path of the original MMDS signal. (Communications Daily, MMDS Industry Gears Up on Standards Issues, Spectrum Planning, April 3, 2000). This would have the effect of significantly reducing the line of sight problem with MMDS and, we believe, will enhance MMDS as a medium for Internet access. ----------------------------------------------------------- Excerpt from WLGS SB-2/A dated May 18, 2000 Development and Licensing of DWCP System We are completing the development of our DWCP system, an acronym for Distributed Wireless Call Processing System. The major feature of the DWCP system is that it allows individual cell phones and other communications units to amplify signals, thereby reducing the need for repeater stations. The DWCP system allows every handset itself serves as a mobile, low-power repeater site, and each unit facilitates the operation of the entire local network within a radius of 10-20 miles. A whole continent populated with these units would theoretically have no need for infrastructure support of any kind. In practice, we or parties to whom we license DWCP will build widely scattered gateway sites that will serve to introduce local signals into long lines, international and satellite service providers and introduce data signals into destination networks while providing a medium for our generation of an ongoing revenue stream. It is expected that there will be a dramatic increase in total network capacity and in individual and traffic-form capacities resulting from the use of the DWCP system. This transmission technique, implemented in the chipsets that are the core of the new technology, embodies very low power transmissions along multiple routes between two mobile or stationary points on the network. The result is a large group of transmission paths blanketing the entire cell compared to the hub and spoke transmissions between the central node and the multiple users of a traditional cellular system. The multiplicity of routes between any two points that is possible with this fabric generates an aggregate capacity for the network that far exceeds a hub and spoke system, where multiple transmission paths converge on a single hub, quickly consuming the available radio frequency in the cell. -24- <PAGE> The low transmission powers needed for the DWCP system have the further potential to allow this new network technology to be overlaid on existing wireless cellular installations without interfering with existing signals in the same frequency. As a result, the new technology has the potential to provide overbuild capacity, incremental returns on investments in frequency, and introduction of new, high-value data and non-voice services on cellular franchises already in place. This new technology is currently being engineered to operate in, among other frequencies, the PCS frequency bands and in so-called free or unlicensed frequency bands in the United States. It is readily adapted to other frequencies - military frequencies and frequencies that may be allocated by foreign governments. By licensing or otherwise transferring this technology to third parties and retaining a substantial royalty interest in it, we believe that we will be able to concentrate on our core business while retaining the potential for a significant revenue stream. Investors should be aware that this system is largely untested and is not widely used, and we cannot ensure that an increase in usage will actually result. We are currently having feasibility studies conducted on DWCP to evaluate its capabilities and market potential. ----------------------------------------------------------- freeedgar.com
