Abstract
A wireless access point device capable of detecting out-of-band interference to the operation of the Wi-Fi network caused by LTE small cell devices such as macrocells and femtocells. A flow processor monitors 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. A mitigation action to change the operational behavior of the wireless access point is then generated and applied to mitigate the effect of the detected interference device on the Wi-Fi network.
