1. A wireless access point geo-location method, comprising: receiving, by a wireless access point, a trigger of determining a wireless access point location coordinate, wherein the trigger includes receiving a first wireless access point connectivity notification; acquiring, by the wireless access point, one or more second wireless access point connectivity notifications associated with one or more user devices, after receiving the trigger; receiving, by the wireless access point, at least three: user device location coordinates associated with the one or more user devices, and wireless signal strengths associated with the first wireless access point connectivity notification and with the one or more second wireless access point connectivity notifications; calculating, via a processor of the wireless access point, user device distances using the at least three wireless signal strengths, a first antenna gain associated with a transmitting antenna of the wireless access point, one or more second antenna gains associated with the one or more user devices, one or more wireless signal wavelengths, and an effect on wireless signal strength by at least one of: a yaw angle, a tilt angle, a roll angle, and a pitch angle of the wireless access point and/or the one or more user devices with respect to the horizontal earth; calculating, via the processor, a wireless access point location coordinate using the at least three user device location coordinates and the calculated user device distances; and storing, at the wireless access point, the wireless access point location coordinate.
