Abstract

A method and apparatus operate a device on a licensed spectrum and an unlicensed spectrum. The device can operate on a Wireless Wide Area Network (WWAN) channel using a WWAN transceiver via a WWAN Radio Access Technology (RAT) base station using a WWAN RAT. The device can communicate with a WWAN RAT Wireless Local Area Network (WLAN) base station using the WWAN RAT via a WWAN RAT WLAN receiver on a WWAN RAT WLAN channel operating on a WLAN frequency. Activation of WLAN frequency-based personal access point using a WLAN personal access point transceiver on the device can be detected. A personal access point WLAN channel of the WLAN frequency-based personal access point can be selected that provides the least desense of the WWAN RAT WLAN channel on the WWAN RAT WLAN receiver.
