Abstract: A coexistence signaling scheme for radio communications is described. In one embodiment, a method for coexistence signaling includes establishing first communications and second communications with separate access points or base stations. The method further includes determining protocol timings of the first and second communications. Based on various communications parameters, protocol timings, and identified interference conditions, the method includes generating one or more priority signals to manage the first and second communications. According to certain aspects, overlapping channel conditions can be avoided while maintaining acceptable communications data throughput.

Abstract: A mesh point operable in a decentralized wireless network is provided. The mesh point includes a transceiver and a processor. The transceiver is operable to communicate with other mesh points. The processor is programmed to execute a routing protocol such that, when a first policy of the routing protocol is selected and a transmission failure occurs between the mesh point and a current parent node of the mesh point, the processor is operable to execute instructions to promote finding another route to a root. The other route to the root is found by referencing a topology, if the topology is available, to identify the route to the root. If the route is not found, the transceiver transmits a one-hop broadcast route request. If the route is still not found, the mesh point enters a route discovery state.

The wireless devices also includes a transmitter that is operable to propagate to one or more adjacent nodes in the mesh network routing information related to the parameterized metrics obtained by the component.
