Abstract
Wireless access point devices having wireless networks operating in accordance with 802.11b/g 2.4 Ghz Wi-Fi can be affected by out-of-band interference caused by LTE small cell devices such as macrocells and femtocells. The wireless access points detect such interference devices using a flow processor to monitor the characteristics of data flows of devices connected to the wireless access point to determine whether they are LTE cells based on MAC address matching or the termination of a flow at a known mobile network operator gateway. When a cell is detected, the wireless access point scans for neighboring wireless networks of neighboring wireless access points which may also be affected by the interference generated by the LTE cell. A management server processes information relating the LTE cell and the neighboring wireless networks and generates a mitigation action to change the operational behavior of the wireless access point and any neighboring wireless access points to mitigate the effect of the detected interference device on the wireless networks.
