          Maximum Peak Power at Antenna Input Terminal:                    38.00 (dBm)
                                       Antenna gain (typical):             18.00 (dBi)


                                     S=         5.00 (mW/cm^2)

    NOTE: The following warning must appear in the installation manual.

    CAUTION:
    This device is intended to be used with an antenna mounted to a fixed, outdoor structure.
    This device is a radio frequency transmitter. It is required to comply with FCC RF exposure
    requirements for mobile transmitting devices. A minimum separation distance of
        80.00 cm or more must be maintained between the antenna and all persons during device
    operations to ensure compliance with the FCC’s rules for Radio Frequency Exposure.
    If this minimum distance cannot be maintained, exposure to RF levels that exceed the FCC's
    limits may result.

    80cm calculation is based on the maximum peak power.
    Max conducted RMS power to antenna port = +30 dBm
    Peak to Average ratio = 8 dB
    Antenna gain = 18 dBi


Maximum peak power to antenna terminal = +30 + 8 dB(p/A) = +38 dBm
