    What should be the antenna gain for WiFi with 50m coverage?

    hai all,

    I would like to design a antenna for wifi 802.11g system with data rate greater than 24Mb/s.

    now my Q? is what should be my antenna gain, in order to cover the 50 meter distance.

    The free-space path loss for this distance and frequency is approximately 75dB.
    Including some other extra losses and assuming a -80dBm receiver sensitivity for 24Mb/s, and +18dBm transmitter output power, a 0 dB antenna gain would be fine to get the link.
