The purpose of this test is to assesses and evaluate the EUT against limits on exposure of people related to electric, magnetic and electromagnetic fields. The EUT meets the RF Exposure limits shown in the Reference levels for Electric, Magnetic and Electromagnetic Fields and Basic Restrictions Limits for Electric, Magnetic, and Electromagnetic Fields tables in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1]. For a detailed requirements and compliance criteria, see clause EN 62311 [8] standard. The maximum RF Output power measured in the tests 3.2 RF Output Power – EN 300 328 in the 2.4 GHz frequency band and 4.5 RF Output Power - EN 301 893 in the 5 GHz frequency band are used to calculate the Maximum Permissible Exposure (MPE) level.
MPE is calculated at 20 cm distance as per the following formula:
SEQ (mW/cm2) = (P x AG) / (4 x π x D2)
Where,
SEQ = Power density
P = Power at Antenna port in mW
AG = Antenna Gain in Numeric form
D = Distance in cm (20 cms)
Use the following formula to convert of Power density SEQ from mW/cm2 to W/m2
SEQ (W/m2) = SEQ (mW/cm2) x (10000 / 1000) = SEQ (mW/cm2) x 10
