Calculated Result and Limit (WORSE CASE IS AS BELOW) Antenna Peak Output Power Density Limit of Power Gain Power (mW) (S) (mW/cm2) Density (S) (Numeric) (mW/cm2) Test Result 4.71dBi 701.46 0.413 1 2.958 28.46dBm Compiles Note: Antenna Gain: 1.70dBi (2.4G Band) Assembly Antenna Gain: 4.71dBi Assembly Antenna Gain (Numeric): 2.958 ERP=28.46+4.71-2.15=31.02 dBm(1264.74mW< 3060mW)
