2      RF Exposure
      Test Requirement:                 FCC Part 1.1307
      Test Mode:                        The EUT work in test mode(Tx).
2.1    Requirements

      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.

               4nR‘
8 = power density (n approprate units, e.q. mWor®)
P = power inout to the antenna (in appropriate urits, e.4., mW).
G = power gain of the antenna in the cirection of interest relative to an isotropic raciator,the power gain
factor, is normally numeric gain.
R = distance to the center of radiation of the antenna (appropriate units, e.4., orn)

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
