2.4GHz: Directional gain = 4.1dBi + 10log(2) = 7.11dBi 5.0GHz: Directional gain = 4.0dBi + 10log(2) = 7.01dBi Z-Wave: 82.4dBuV/m=-12.83dBm Conclusion:

The formula of calculated the MPE is:

CPD1 / LPD1 + CPD2 / LPD2 + etc. < 1 CPD = Calculation power density LPD = Limit of power density WLAN 2.4GHz + WLAN 5GHz + BE LE + Zigbee + Z-Wave

= 0.6866 + 0.0997 + 0.0003 + 0.0387 + 0.000017= 0.825317 Therefore the maximum calculation of this situation is 0.825317, which is less than the 1 limit. FREQUENCY BAND (MHz) MAX POWER (dBm) WIFI (5.0G) WIFI (2.4G) BT LE Zigbee
