Tracking Movement Through The Wall....Wirelessly

Anyone who has played popular military based games like Call of Duty will be familiar with a small navigational map typically located on one of the corners of the games screen allowing the player to see not only where they are located on the game map, but also where the enemy is located. In certain games their location is revealed on the map even if they are inside a building.

Could you imagine if that technology really existed what that would mean for law enforcement agents and military personnel on the combat field? Not really to my surprise this technology does exist! It was developed and revealed in its infancy by Joey Wilson and Neal Patwari from the Uniservsity of Utah in 2009. The team were working on a wireless system capable of tracking movement even inside of a building out of plain sight of people on the outside of the building. Take a few minutes to watch the video as Joey explains and demonstrates  how the system works:
