Everytime we use GPS with our cellphones, we have allowed location technology to find our device so our device can tell us where we are on a map. While location services work great in the outdoors, indoors their performance is not as robust, because of the roof between the mobile device user and a satellite. But there is growing demand for indoor location services, and the fact that we now have a competition taking place between cell service and wi-fi to provide better indoor location says a lot about the size of that dema</p><div> </div>

Geofencing also becomes practical. That’s where artificial boundaries prompt actions, such as an alert when a device crosses a cutoff point. And, of course, advertising and marketing stand to benefit from it. Using ‘hyperlocal marketing,’ businesses push targeted ads or special offers to consumers as they move around.”</li>

The approach measures signal timestamps with nanosecond accuracy to deliver location data typically within a meter using the Fine Timing Measurement protocol from IEEE 802.11-2016. Another Wi-Fi standard in the works, <a href="http://www.ieee802.org/11/Reports/tgaz_update.htm" target="_blank">802.11az</a>, could offer centimeter accuracy in a few years.”</li>

In that case, it’s hard to know if you’re far away or whether a wall is obstructing the signal. RSSI fingerprinting is more accurate, but requires site surveys, which become expensive, he said. The alliance touts Wi-Fi Location as enabling location-based services on existing WiFi infrastructure; there’s no need for beacons, for example.”</li>
