GloPos Confirms Indoor Positioning Accuracy of 7.7 to 12.5 Meters in Independent Tests press release tells about a new positioning technology. GloPos, the developer of a software-only positioning technology that makes all mobile phones location aware, has confirmed an indoor positioning accuracy of 7.7 to 12.5 meters in an independent test of its software conducted by VTT, The Technical Research Center of Finland (very trustworthy test laboratory in Finland). The technology is promised to work outdoors, indoors, and even underground using only a cellular network (no GPS or W-LAN needed). Testing of the outdoor, indoor and underground accuracy of GloPos software was conducted by VTT at the Helsinki City Center on May 20, 2010. The GloPos application ran on a standard GSM-only mobile phone and used only a cellular network to make phone location aware. Sounds interesting.
The current positioning technology can be used for many things, for good and bad. IPhone and iPad Lost in the Trash, Found With MobileMe article tells how the location functionality helped to find lost iPhone and iPad.
