Mobile device for a smart relay network
View Patent ↗A wireless relay node network includes a plurality of relay devices wherein each relay device is configured to receive a first wireless signal in a first frequency band, and transmit a second wireless signal derived from the first wireless signal using a first set of network use parameters. The plurality of relay devices includes at least a first relay device and a second relay device. The first relay device is configured to select the first set of network use parameters from network resources available for communicating over the wireless relay node network based, at least in part, on a control signal received from the second relay device. The second control signal identifies a second set of network use parameters used by the second relay device.
