Patent Images
1. A method of using beacon-related information, comprising:
- using, by a wireless device, an indication regarding transmission of at least one next beacon by at least one neighboring access point, wherein each beacon of the at least one next beacon comprises an identifier of an associated wireless network; and
scanning, by the wireless device, for the at least one next beacon.

Abstract
Beacons may be grouped to facilitate neighbor discovery in a wireless network. For example, neighboring access devices such as IEEE 802.11 access points may cooperate to transmit beacons in a group. In this way, a wireless device seeking to discover the neighboring access devices may scan for the beacons for a shorter period of time. An indication may be provided to enable a wireless device to more efficiently scan the beacons. For example, the indication may indicate the channel the wireless device should scan to receive the next beacon that is to be transmitted. In addition, the indication may include information relating to the transmission time of the next beacon.
