Abstract
A method and wireless device merge multiple unsynchronized beacon groups in a wireless network, each beacon group including at least one wireless device. A first beacon is received from at least one first wireless device in a first beacon group (S), the first wireless device having a first directional antenna. A second beacon is received from at least one second wireless device in a second beacon group that is not synchronized with the first beacon group (S), the second wireless device having a second directional antenna. A first response beacon is relocated (S) and sent (S) to the first wireless device in the first beacon group. The relocated first response beacon instructs the first wireless device to relocate the first beacon. Accordingly, the second beacon, the relocated first response beacon, and the relocated first beacon are synchronized.
