Abstract
A mesh network relaying device includes at least a first radio, a second radio, and a third radio. During normal operation, the device communicates with other network nodes via the first and second radios, the radios operating at the best available bandwidth. When the device identifies a communication link failure in one of the first and second radios, the device activates the third radio and operates the first, second, and/or third radios at narrower bandwidths. When the communication link failure is resolved, the device deactivates the third radio, and resumes communication via the first and second radios at wider bandwidth.
