Find your way round MWC with free 'indoor GPS' app

sensewhere giving away SatNav-type product to Android users.

The firm says the app showcases its self-correcting, self-generating indoor location tech, which requires just the standard wireless technology inside most Android phones to work.

It does this using whatever RF references are available, without the need for additional infrastructure, sensors or ‘fingerprinting’ of locations.

The trick seems to be in the self-correction of the system. Thus, when a consumer uses the app, their device automatically maps the local RF topography and updates the overall system.

Rob Palfreyman, CEO, sensewhere, said: "The fact that our system is self-generating/self-correcting is the real 'secret of the sauce', combined with our super-accurate proprietary algorithms.

"We have, essentially, overcome all the limitations of previous systems to remove every barrier to entry. sensewhere is cost-effective, accurate, highly-available and, best of all, doesn't require a big up-front investment.
