METHODS AND APPARATUSES FOR USE OF SIMULTANEOUS MULTIPLE CHANNELS IN THE DYNAMIC FREQUENCY SELECTION BAND IN WIRELESS NETWORKS

摘要

The present invention relates to wireless networks and more specifically to systems and methods for selecting available channels free of radar signals from a plurality of 5 GHz radio frequency channels. In non-limiting embodiments, exemplary systems, methods, and apparatuses are provided that can facilitate reducing false detections and/or network downtime in exemplary mesh networks employing dynamic frequency selection (DFS) channels. In a non-limiting aspect, radar information can be propagated among exemplary mesh nodes, including location information, to facilitate reducing false detections and/or network downtime in exemplary mesh networks. In addition, in further non-limiting aspects, exemplary embodiments can transmit signals to facilitate silencing one or more DFS channels and/or collaborative mesh node identification and/or discrimination of radar signals and false detections, among other non-limiting aspects provided.

1. A method comprising:
receiving in a mesh network, at a host device comprising a processor, an indication of a suspected radar event on at least one dynamic frequency selection (DFS) channel; determining, with the host device, whether the suspected radar event is a valid radar event, based at least in part on the suspected radar event; and propagating, in the mesh network, radar information regarding at least one of the suspected radar event or the valid radar event to at least one of another host device or a cloud intelligence engine associated with the mesh network.
