Abstract
Technologies directed to multi-tier coordinated dynamic frequency selection (DFS) service in a multi-tier wireless network are described. One method includes receiving, by a first wireless device, first data associated with a first set of DFS channels. The first wireless device performs a CAC on each DFS channel of the first set of DFS channels in a specified order. The first wireless device identifies a second set of DFS channels in which no radar event is found during the respective CAC and generates second data associated with the second set of DFS channels. The first wireless device receives a first request for the second data from a second wireless device. The first wireless device determines a receive signal strength indicator (RSSI) value associated with the first request and sends a first response, including the second data and the RSSI value, to the second wireless device
