Installation Manual

The validation of this implementation was performed according to IEC 62232:2017 standard using the
test input parameters from the following table of the standard:
•
RF Power: 1 W
• Antenna Length: 1.3 m
• Gain: 18 dBi
• 3 dB elevation beamwidth: 6.5 deg
• 3 dB azimuth beamwidth: 65 deg
• Frequency: 2140 MHz
The SAR results computed using this implementation of the IEC 62232:2017 standard formulas B.28,
B.29, and B.30, and a body mass of 46 kg agree with all the applicable reference results from the IEC
62232:2017 standard and are summarized in the following table. Therefore according to the standard,
the implementation passes the validation test.

Equivalent Plane Wave Power Density Evaluation
Compliance evaluation with respect to the ICNIRP reference levels and U.S. FCC MPE limits in the
VHF band is based on the IEC 62232:2017 standard clause B.4.2.1 for estimating the spatial-peak
equivalent plane wave power density. Similar approach is also described in US FCC OET Bulletin [2].
Specifically the spherical formula B.15 from IEC 62232:2017 standard is used to calculate the spatial-
peak equivalent power density:
