Upstart PoLTE Cracks Logistics Location Challenges Using LTE

When you think about positioning, the first thing that comes to mind is GPS. The Defense Department Global Positioning System uses a constellation of 24 satellites, each containing a highly accurate atomic clock. Your location is determined by measuring the speed of light delay triangulating from three or more of those satellites. But GPS has some limitations that keep it from being a reliable solution for tracking objects. First, GPS requires an unobstructed view of the sky so that the satellite signals can reach the GPS receiver.  Secondly, propagation interference caused by a variety of factors that include reflections off buildings and landscape features, such as mountains, make calculating the distance to the satellite uncertain. Add that to the fact that the computing in a GPS device takes place in the device, and you have limitations due to battery life. PoLTE has another idea. This is a Richardson, Texas-based software company whose location technologies seamlessly track the internet of things and mobile devices indoors and outdoors via its cloud-based, virtualized location platform.
