    Although a maximum of 1000 remotes is supported per base station, this number would result in low data rates. Instead, to ensure high data rates, Wi-LAN suggests a standard where 75 remotes can maintain constant 128 kbps communication with a base station. Since it is unlikely that all units will be active at the same time, the total number of remotes for planning purposes can be increased by a factor of three, so that a maximum of 225 (3 x 75) remotes per base station is recommended.

    To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all losses. For a reliable link, Wi-LAN recommends that the system gain plus all antenna gains be greater than the sum of all losses by 15 dB. This amount is the fade margin.

  • Page 123: Antenna Gain

    Calculating a Link Budget Antenna Gain To ensure the best range and interference suppression, the external antenna should be directional, focusing the radio energy in one direction (toward the other end of the link) rather than onmi-directional. Use of a directional antenna also reduces interference from other systems operating at the same frequency.

    The Wi-LAN recommended fade margin for the Hopper Plus 120-24 is a minimum of 15 dB. The sum of the cable losses, connector losses, propagation losses, and the 15 dB required fade margin should be less than the sum of the system gain and antenna gain.
