VIDEO: Nokia working on indoor positioning GPS

Here's an interesting little teaser video from Nokia about something being developed deep in their Helsinki research labs - a kind of indoor positioning GPS.

Rather than develop super GPS chips that can work through walls, Nokia's system uses existing infrastructure - the building's Wi-Fi network - to triangulate a phone's position.

The company claims an accuracy of up to one metre. Watch now for more and we'll bring you updates as and when we hear 'em.
