1 MAXIMUM PERMISSIBLE EXPOSURE (MPE)
1.1 Standard Applicable:
        According to §1.1307(b)(1), systems operating under the provisions of this section shall be
        operated in a manner that ensure that the public is not exposed to radio frequency energy
        level in excess of the Commission’s guideline.


        This is a Mobile device, the MPE is required.


        According to §1.1310 and §2.1093 RF exposure is calculated.
