In this session we will start by looking at the techniques used to locate devices through wireless signals, and how they apply to GPS and WiFi positioning.

In particular we will look at the GPS system. How can it calculate a location from satellites orbiting earth? You probably heard it’s all about time….
We will then dive into WiFi positioning. How does it differ from traditional wireless location systems? Did I mention 75 million reference points? Compare that to 31 satellites for GPS. None of which are controlled or managed for the purpose of positioning.

Finally, we will look at how GPS and WiFi positioning can be combined to deliver the same level of location quality whether indoors or outdoors, in the country or downtown.
