GPS has created an expectation of location accuracy that is not yet widely available in indoor spaces such as warehouses, hospitals, airports, malls, and concert venues. Current indoor localization technologies include Bluetooth, IR, Ultrawideband, and WiFi. Among these, WiFi is both relatively inexpensive and offers substantial infrastructure such as smartphones and access points. However, the current WiFi method for determining position is measuring signal strength to estimate the distance between the device and an access point. Unfortunately, this method produces poor and inconsistent results. A new technology has emerged that uses extremely precise Fine Time Measurement (FTM) to measure time of flight of WiFi signals to establish distance and location. This technology has recently been embedded into a reasonably inexpensive WiFi chip that appears to offer an opportunity to develop a profitable first product for crowd lighting in concert venues, which appears to be a sufficiently large and presently underserved market. We have reviewed the somewhat limited FTM research, and have been able to implement FTM in a product that appears to offer commercial success.
