2. MPE Calculation

   2.1 WIFI 2.4G MPE

   Based on safety distance (r) 20cm, the antenna gain (G) is 2.891 Numerical, and the
   highest power output (P) is 60.814mW, the power density (S) is 0.034977mW/cm2.

   RF Exposure Calculations:
   S = (P * G) / (4* π * r2) or r =   (P * G) / (4 * π * S)

   Where :
   Based on safety distance (r)=             20 cm
   Highest Power Output (P)=              17.84 dBm =                   60.814 mW
   Antenna Gain (G)=                       4.61 dBi =                     2.891 Numerical
   MPE (S) = (P*G) / (4*π*r ) = = (201.837*2.891)/(4*π*202)=
                           2
                                                                      0.034977 mW/cm2


   2.2 BT MPE

   Based on safety distance (r) 20cm, the antenna gain (G) is 2.570 Numerical, and the
   highest power output (P) is 11.561mW, the power density (S) is 0.005911mW/cm2.

   RF Exposure Calculations:
   S = (P * G) / (4* π * r2) or r =   (P * G) / (4 * π * S)

   Where :
   Based on safety distance (r)=              20 cm
   Highest Power Output (P)=              10.63 dBm =                 11.561 mW
   Antenna Gain (G)=                        4.10 dBi =                  2.570 Numerical
   MPE (S) = (P*G) / (4*π*r ) = = (11.561*2.570)/(4*π*202)=
                           2
                                                                    0.005911 mW/cm2


   2.3 WIFI 5G MPE

   Based on safety distance (r) 20cm, the antenna gain (G) is 3.776 Numerical, and the
   highest power output (P) is 84.918mW, the power density (S) is 0.063791mW/cm2.

   RF Exposure Calculations:
   S = (P * G) / (4* π * r2) or r =   (P * G) / (4 * π * S)

   Where :
   Based on safety distance (r)=              20 cm
   Highest Power Output (P)=              19.29 dBm =                 84.918 mW
   Antenna Gain (G)=                        5.77 dBi =                  3.776 Numerical
   MPE (S) = (P*G) / (4*π*r ) = = (84.918*3.776)/(4*π*202)=
