1. A method, comprising:
by a first computing device in a wireless network:
transmitting a frame over the wireless network to one or more stations, the frame being a trigger frame to coordinate resource allocation among the one or more stations;
receiving, from one or more second computing devices in the wireless network, a received signal strength indicator value with an associated identifier for each of the one or more stations, the received signal strength indicator value and associated identifier being determined by the one or more second computing devices at least partly by detecting the frame that was transmitted to the one or more stations;
matching the associated identifier to a respective address for each of the one or more stations;
determining a distance value from the received signal strength indicator value for each of the one or more stations;
determining a location of each of the one or more stations using the distance values; and
transmitting, to one or more third computing devices, the location and the respective address of each of the one or more stations.
