Patent ID: 8903320

Claim:
A computer-implemented method at a first communication network for reducing interference between the first communication network and a second communication network, the method comprising: receiving message packets at a node in the first communication network; determining by the node whether the message packets originated from the second communication network, the second communication network being any external network located proximate to the first communication network; responsive to a determination that the message packets originated from the second communication network, modifying a parameter by the node to operate below a threshold in order to prevent interference by the first communication network on the second communication network; receiving a beacon message from the second communication network, the beacon comprising a clear-to-send (CTS) field with a duration value indicating how long a sender has control of a communication channel; and responsive to modifying the parameter below the threshold to prevent interference of the first communication network on the second communication network, ignoring the duration value of the CTS field.
