Abstract
A centrally controlled dynamic frequency selection (DFS) mechanism is defined that uses a historical analytical database to define DFS hop patterns, which allows for a better probability of picking a non-interfering channel but also meets the performance requirements of the mesh and satisfying the timing constraints of DFS. A method for performing dynamic frequency selection (DFS) is disclosed, comprising: receiving, at a gateway, measurement reports from a radio access node regarding observed utilization of a 5 GHz radio frequency band shared with a plurality of radio access nodes; determining, based on the received measurement reports, a frequency hop pattern at the gateway; and sending the frequency hop pattern from the gateway to each of the plurality of radio access nodes, thereby enabling compliance with DFS regulations using a centralized gateway.
