Nokia links up with Bluetooth 4.0 for indoor positioning, because anything Google can do, it can do better

Not to be outdone by the mobile mammoth that is Google, Nokia's prepping its own version of indoor maps for wireless users. Rather than run the risk of being a me too! product, Espoo's Research labs have chosen Bluetooth 4.0 as the main ingredient for its in development location service. The Finnish company's hoping to get a slew of partners onboard so it can begin outfitting retail shops, malls and other well-trodden public spaces with inexpensive antenna arrays that would track a user's movements via device-embedded Bluetooth tags. But indoor positioning for mobile-wielding users isn't the only endgame here, as the tech could also find its way into shopping carts -- useful for gathering analytics on consumer habits. It's certainly a privacy trade-off, but by now you should be well comfy with the notion that digital convenience always comes at a cost. Hit up the source below to take a peek at the proposed equipment.
