RF Exposure
1.1
Test Requirement:
FCC Part 1.1307
Test Method:
FCC Part 2.1091
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.

E (V/m) =
30 × P × G
Power Density: Pd (W/m²) =
E2
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
