    Hi there, I am planning to deploy an access point using 4 x WAP54G into different sector antennas (18dB) for 4 sectors in a small city. Tweaking up power, single transmitting and bla bla bla is assumed.
    Channel assignment: 1 north, 11 south, 6 east , 6 west. east and west are back to back
    I would like to know if this is gonna work and what should I know that has to be done.

    I'll assume you are already using directional 90-degree antennas.
    The higher the front-to-back ratio on your antenna, the less leakage there will be on the backside of East to interfere with West.

    I'd suggest 1, 4, 8, and 11. These channels have some overlap, but it's not severe. If you can, separate them by 4 feet or more to reduce crosstalk.

    Thanks for the tip. I am using 100 deg antennas so there is some overlap (they say this type of pannel would have a 18dB gain but I am skeptikal and only counting on 12..14dB).
    What would be the field strength on a simple dipole antenna at about 1mile distance on the frontal lobe of a 14dB antenna with a -15dB RF level output - line of sight?

    Hi there,

    System has been deployed and tests indicate that the field strength is fair to good (1/2mile -51dBm line of sight). We used 4 sectors with 4 x WAP54G "tweaked" to deliver 84mW which eventually brings an "impressive" eirp helped by 4 pieces of 18dB pannel, theoretically we are speaking about 5W per sector :eek:
