Grant Notes

Output power is maximum peak conducted. <br> This device supports IEEE 802.11 b/g/n 20 and 40 MHz channel bandwidths. <br> This device has integrated DSS, DTS and NII transmitters certified under the same FCC ID. <br> SAR compliance for body-worn operating configurations is limited to the belt- clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 5 mm separation between the device and the user's body. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR values for body-worn accessory and simultaneous transmission use conditions are 0.79 W/kg and 1.50 W/kg, respectively.
