Long Range Wifi Booster

With Increased Transmitter Power

The long Wifi Booster has an Extended WiFi range with increased transmitter power.   The ALFA Long Range WiFi Amplifier provides up to 800 mW of transmit power. Coupled with its highly sensitive and upgradeable 5 dBi Omni-directional antenna, this kit can achieve 2.5 Watts of total output power (EIRP).

when calculating your total output that the FCC only allows 36dBm EIRP (4 watts).  The transmitted power must be configured correctly to prevent potential interference problems due to the effective isotropic radiated power exceeding the limits as defined in FCC part 15.247(i).  The antenna can only have a maximum gain of 6dBi. If the power at the transmitter is lowered by 1dB, the antenna gain can be increased by an additional 3dB. For example, if an installation reduced power at the transmitter to 29dBm, it could use an antenna having a gain of 9dBi. In general, for every 1dB power reduction at the transmitter from 30dBm, installation can add 3dB gain at the antenna.

The breakdown of transmitter versus antenna gain is:

    30dBm transmit - 6dBi antenna
    29dBm transmit - 9dBi antenna
    28dBm transmit - 12dBi antenna
    27dBm transmit - 15dBi antenna
    26dBm transmit - 18dBi antenna
    25dBm transmit - 21dBi antenna
    24dBm transmit - 24dBi antenna
