f = frequency in MHz

Friis transmission formula: Pd = (Pout*G)/(4*pi*r2)

Where Pd = power density in mW/cm2, Pout = output power to antenna in mW; G = gain of antenna in linear scale, Pi = 3.1416; R = distance between observation point and center of the radiator in cm

Pd id the limit of MPE, 1 mW/cm2. If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually.

Test Result of RF Exposure Evaluation

BLE Mode GFSK

Output power to antenna (dBm)
2.85

Output power to antenna (mW)
1.93

Power Density at R=20cm (mW/cm2)
0.0005

Limit (mW/cm2)
1.0

Result PASS

Remark: antenna gain=1.2dBi So a SAR test is not required
