1. Maximum Permissible Exposure
1.1. Applicable Standard
    Systems operating under the provisions of this section shall be operated in a manner that ensures that
    the public is not exposed to radio frequency energy levels in excess limit for maximum permissible
    exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been
    defined as a mobile device whereby a distance of 0.2 m normally can be maintained between the user
    and the device.

1.2. MPE Calculation Method

                30  P  G                                                  E2
    E (V/m) =                                Power Density:   Pd (W/m²) =
                    d                                                       377
    E = Electric field (V/m)
    P = Peak RF output power (W)
    G = EUT Antenna numeric gain (numeric)
    d = Separation distance between radiator and human body (m)
    The formula can be changed to

    Pd =
           30  P  G
            377  d 2
    From the peak EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the
    gain of the used antenna, the RF power density can be obtained.
