Mati Wax, CTO of US Wireless Corporation, is shown illustrating a point in his presentation entitled "Multipath in Cellular Networks: Impediment or Opportunity?".
US Wireless has conducted extensive studies and field trials that lead to an understanding of the opportunities in multipath, providing coverage in environments lacking line of sight, and the correlation between multipath pattern and the physical location of a wireless caller. This tight correlation between multipath pattern and physical location gave birth to US Wireless' proprietary Location Fingerprinting technology and the RadioCamera(TM), an efficient and cost- effective method of locating and tracking cellular callers for wireless 911 and other value-added applications for the cellular road warrior.
Professor Donald Cox of Stanford University is shown accepting a small token gift from Bob Roy, President of WCA, following Professor Cox's prsentation: "Broadband Wireless Access: A Perspective"
This talk was prepared for a workshop on Broadband Wireless Access and is aimed more at provoking thought and raising issues than at providing precise answers. Some of the issues addressed area) Data rate, range and power relationships, b) Two-way asymmetrical link data rate limitations, c) Challenges for frequencies above 20 GHz, and d) Factors limiting line-of-sight. Issues are discussed and possibilities are presented within the context of recent wireless industry history and experiences. The perspectives presented are based on the speaker's experience over the last 30 years.
