SYSTEMS, METHODS, AND DEVICES FOR INDOOR POSITIONING USING Wi-Fi

摘要

Example systems, methods, and devices for identifying location of wireless communication device are disclosed. In an example embodiment, the device may be configured to transmit GPS coordinates to one or more Wi-Fi access points, measure distance between the wireless communication device and three or more Wi-Fi access points using a ranging technique, and determine location of the wireless communication device based, at least in part, upon the distance between the wireless communication device and the three or more Wi-Fi access points, and a time delay in propagation of one or more Wi-Fi signals between the wireless communication device and the three or more Wi-Fi access points Methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.
