Abstract:
1. A method, comprising: transmitting data directly between a first endpoint device and a second endpoint device on a primary channel; identifying, with the first endpoint device, a second channel free from having an acceptable level of interference to exchange data between the first endpoint device and the second endpoint device; in response to determining that the data transmitted on the primary channel is not received, retransmitting the data on the secondary channel directly between the first endpoint device and the second endpoint device when an unacceptable level of interference is detected on the primary channel: receiving a data packet on the primary channel from the second endpoint device; and responding to the received data packet with another data packet that includes a frequency associated with the secondary channel, wherein the second endpoint device is configured to store the frequency associated with the secondary channel and continue to exchange data over the primary channel with the first endpoint device.
