STM Wireless Awarded Patent On New CDMA Technology; Patented
Technology Can Reduce Cost of Broadband VSAT and Associated Hub Equipment

     STM WIRELESS, INC. (STM), (Nasdaq NM:STMI) today announced that its patent application for a special form of Code Division Multiple Access (CDMA), called Cyclic Code Phase Multiple Access (CPMA) has been awarded under US patent US6108317.

     The patented technology provides all the benefits of classic CDMA, while significantly reducing the cost of the network infrastructure, particularly for applications involving a large number of simultaneous users as encountered in broadband satellite networks. Designed for a low to moderate throughput in the upstream channel, the technology is applicable to Ka-band SOHO and consumer VSAT applications and is complementary to STM’s current line of TDMA VSATs.

     Conventional CDMA techniques, when applied to VSAT networks, use a unique code for each VSAT transmission, requiring an independent receiver for each code. For large networks, this can result in a very large and expensive hub. STM’s CPMA enables simultaneous demodulation of transmission by a large group of VSATs using a common receiver, thereby greatly reducing the size and cost of the hub. This is done by using a cyclic manipulation of a common base code to create the CDMA code set. By constructing a double-cyclic code set, full channel loading is achieved with the bandwidth efficiency of QPSK.

     The CPMA technique developed by STM is part of its ongoing research and development to innovate new technologies which may be used in DVB based two-way broadband satellite networks using the Ka-band spectrum with very small antennas. While the patented technology has been developed for use in bent-pipe satellites, it can also be used in on-board processing systems in order to reduce the size and complexity of onboard receivers. The CPMA technology results in efficient use of available spectrum, in addition to allowing a significant reduction in the size and cost of the VSAT transmitter and associated hub equipment.

      STM plans to explore the application of CPMA in the design of low cost VSAT and hub equipment for future Ka-Band networks. Emil Youssefzadeh, STM’s Chief Executive Officer, said, “Our vision of future broadband VSATs involves a 12 to 18 inch Ka-band terminal that can be deployed in a mass consumer market for use with spot beam satellites that are scheduled to go into operation over the next two to three years. Our new CPMA technology and the patent award is a major milestone for making such a vision a reality.”
