                                 Maximum Permissible Exposure


Test Requirement(s):             §15.247(f):

RF Exposure Requirements:        §1.1307(b)(1) and §1.1307(b)(2): 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 of the Commission’s
                                 guidelines.

RF Radiation Exposure Limit:     §1.1310: As specified in this section, the Maximum Permissible Exposure
                                 (MPE) Limit shall be used to evaluate the environmental impact of human
                                 exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except
                                 in the case of portable devices which shall be evaluated according to the
                                 provisions of Sec. 2.1093 of this chapter.

                 MPE Limit: EUT’s operating frequencies @ 2400 - 2480 MHz; Limit for Uncontrolled
                 exposure: 1 mW/cm2 or 10 W/m2

                 Equation from page 18 of OET 65, Edition 97-01

                         S = PG / 4πR2       or       R = √(PG / 4πS)

                 where, S = Power Density (mW/cm2)
                         P = Power Input to antenna (mW)
                         G = Antenna Gain (numeric value)
                         R = Distance (cm)
