Part 1.1310 Limits for Maximum Permissible Exposure (MPE) 1.1 Test Procedure An MPE evaluation for was performed in order to show that the device was compliant with §2.1091. The maximum power density was calculated for each transmitter at a separation distance of 20cm. For each transmitter the maximum RF exposure at a 20 cm distance using the formula: Conducted PowermW = 10ConductedPower ( dBm ) /10 Conducted PowermW × Ant.Gain PowerDensity = 4π × (20cm ) 2 EIRP(mW ) PowerDensity = 4π × (20 cm ) 2
