The MPE calculations are submitted for multiple frequency exposure criteria. The ratio of the
field strength or power density to the applicable exposure limit at the exposure location was
determined for each transmitter below and the sum of these ratios does not exceed the
1 mW/cm^2 limit for uncontrolled exposure / general population exposure limits detailed in CFR
47, Part 1.1310.
