Introduction Ctt March 1, 2002 Page B2 Introduction The ARCi Internet system, deployed in conjunction with the Vyyo Broadband Wireless Access System, provides a complete end-to-end solution for ISPs and other fixed wireless operators seeking to expand their markets by offering wireless delivery of the Internet to their customers at performance levels that normally exceed DSL. Figure 1 Typically the ARCi Hub Antenna is mounted on a building roof or tower structure with an unobstructed (as possible) view of the geographic area to be served by the ARCI Internet system. Each ARCi Hub Antenna “illuminates” a horizontal arc of about sixty degrees and a distance of about five miles. Therefore, an omni directional system would Hub Antenna Hub Cable Modem ARCi Subscriber Antenna WWW Wireless Modem Wireless Hub The ARCi Internet Solution ARCi Gateway Network Manager March 1, 2002 Page B3 require six ARCi Hub Antennas arranged pointing outward spaced every 60 degrees. A system only looking up a narrow canyon from one end might require only one ARCi Hub Antenna. Cables are run from the antenna(s) into the building to the hub equipment room. The ARCi Subscriber Antenna is mounted outdoors at the subscriber location with line of sight to the hub antenna. A single cable is run to the modem and computer inside the subscriber location.
