Tiami Networks

Tiami Networks proposes the use of public digital TV (DTV) stations as positioning beacons for three-dimensional indoor tracking in GPS-denied environments without pre-deployed infrastructure. DTV stations provide near-ubiquitous coverage across the United States since a single high-power DTV station has a range of 35-40 miles. Our preliminary analysis shows that DTV signals have up to 1000 times (30 dB) better coverage and outdoor-to-indoor penetration compared to FirstNet cellular radio transmissions. We will develop a wearable, battery-powered DTV positioning receiver that exploits the DTV ATSC 3.0 broadcast waveform to record DTV signal strengths and times of arrival from multiple stations. The measurements are used to infer the 3D receiver location since DTV station locations and mast heights are fixed. The ATSC 3.0 waveform is similar to 5G, thus many of the signal processing techniques that provide high-precision positioning accuracy in 5G networks are reusable to attain the
