     Maximum Permissible Exposure Compliance Requirement


1. LIMITS
The limit for general population/uncontrolled exposures
 Frequency                         Power density(mW/cm2)          Averaging time(minutes)
 300MHz~1.5GHz                     F/1500                         30
 1.5GHz~100GHz                     1.0                            30



 Frequency(MHz)                    Power density(mW/cm2)          Averaging time(minutes)
 2402                              1.0                            30
 2412                              1.0                            30
 2437                              1.0                            30
 2462                              1.0                            30
 2480                              1.0                            30


2. EUT RF Exposure

The EUT has one RF module which is a 2.4G wifi module.

2.4G wifi module: The Max Conducted Peak Output Power is 24.48dBm (280.5mW) in channel 1 of
802.11n20; The antenna gain of this antenna 1 is 5dBi

5dB logarithmic terms convert to numeric result is nearly 3.16.

                             PG
According to the formula S= 4R 2 ,we can calculate S which is MPE.



Now , R=20 cm, P=280.5mW, G=3.16

       PG     280.5 * 3.16
So,S= 4R  = 4 * 400 * 3.14 =0.176 mW/cm2
        2




So the MPE comply the requirement.
