1. A method, comprising:
determining a plurality of estimates of antenna gain for an antenna associated with a wireless access point (AP), the plurality of estimates of antenna gain relating to a plurality of wireless stations (STAs) associated with the AP,
wherein determining the plurality of estimates of antenna gain is based on a path loss between the AP and a first STA of the plurality of STAs,
wherein the path loss is determined based on a distance between the AP and the first STA, and
wherein the distance is determined based on at least one of: (i) a previously available orientation for the antenna or (ii) a time of arrival for one or more network messages between the AP and the first STA; and
determining an orientation for the antenna based on the plurality of estimates of antenna gain and a plurality of properties for the antenna.
