Nokia’s keeping mum about exactly how the technology works, for now, but has said it’s based on wireless networks. The firm’s also said that the technology still needs a scalable solution to make it work and admitted that mapping the guts of each building “is quite a challenge”.

Based on wireless networks ? so you mean something like the Cisco Location Appliance but integrated on the device ? I would be curious to see how it works but it probably makes intensive used of the wireless network infrastructure…
