(fMHz / 1500 mW/cm2 == fMHz / 150 W/M2 ) The power density is calculated as: Pd = power density in mW/cm2 Pt × G Pt = transmit power in milliwatts Pd = 4×π × r2 G = numeric antenna gain r = distance between body and transmitter in centimeters. FCC Limits: 926.8MHz / 1500 = 0.618 mW / cm2 @ 20cm IC Limits: 926.8MHz / 150 = 6.18 W / M2 (@ 0.2M) Power level 3 Max antenna gain = 6.82 dBi = 4.81 numeric Max TX power = 22.47 dBm = 177 milliwatts results: PD = (177 x 4.81) / ( 4 x pi x 20cm2) = 0.169 mW / cm2 @ 20 cm W/m2 = 10 times mW/cm2 = 1.69 W/M2 @ 0.2 M Power level 2 Max antenna gain = 5.49 dBi = 3.54 numeric Max TX power = 21.78 dBm = 151 milliwatts results: PD = (151 x 3.54) / ( 4 x pi x 20cm2) = 0.106 mW / cm2 @ 20 cm W/m2 = 10 times mW/cm2 = 1.06 W/M2 @ 0.2 M Power level 1 Max antenna gain = 5.82 dBi = 3.82 numeric Max TX power = 9.00 dBm = 8 milliwatts results: PD = (8 x 3.82) / ( 4 x pi x 20cm2) = 0.006 mW / cm2 @ 20 cm W/m2 = 10 times mW/cm2 = 0.06 W/M2 @ 0.2 M 100tcp_report mpeb.docx Rev. b
