ADDENDUM TO THE AIRPRO-SE USER MANUAL
TRANSMITTER POWER SETTINGS
The maximum output power allowed by FCC Rule Part 15 depends on power spectral density
(PSD) at a given output power setting, on antenna gain, and on the amplitude of emission bandedge
energy in restricted bands starting at 2483.5 MHz and 2390 MHz.

Compliance with RF Exposure Guidelines in FCC Rule para. 1.1307(b)1
The AIRPRO transmitter must meet the RF exposure requirements described in paragraph
1.1307(b)1 of FCC’s Rules. The specific requirement for a transmitter of this type is that the
maximum permissible exposure level (MPE) meets the limits for “General
Population/Uncontrolled Exposure “ (Table 1, para. 1.1310). The required MPE is 1.0 mW/cm2.
For each antenna used with the AIRPRO transmitter, the antenna gain and maximum output
power
are used to calculate the distance from the antenna at which MPE is exceeded. The installer shall
take all reasonable steps to maintain this separation distance between the antenna and personnel.
Calculating Minimum Separation Distances to meet MPE Requirements
E2/377 = S, W/m2
Specification: 1 mW/cm2 = 10 W/m2, Emax = 61.4 V/m
Ev/m = (30*P*G)0.5 / d, P= power in watts, G = ant. gain over isotropic, d = distance, meters
d = (30*P*G)0.5 /61.4
Ant Gain, dBi RF In, dBm Minimum Dist, cm
0.0 28.0 7.1
8.0 28.0 17.8
15.0 27.0 35.5
24.0 24.0 70.9
