1. A system, comprising:
- a wireless access point comprising at least one circuit or processor configured to;
obtain a probe request from a wireless device, the probe request received from the wireless device for information about available wireless networks and not including an access point identifier corresponding to the wireless access point;
extract identifying information corresponding to the wireless device from the request;
originate a message, which is not a probe response and not a message received from the wireless device and includes the access point identifier corresponding to the wireless access point and the identifying information; and
transmit the message including the identifying information and the access point identifier to at least one server, which is configured to determine a location of the wireless device based on a stored location corresponding to the access point identifier.

Abstract
Disclosed are various embodiments of a wireless access point. An 802.11 probe request frame is obtained from a wireless device in a wireless access point. Identifying information about the wireless device is extracted from the 802.11 probe request frame. The identifying information and an access point identifier corresponding to the wireless access point to at least one server via a network, from which location and/or proximity to the wireless access point can be determined.
