[4eyes] Indoor location tracking

[Tobias Hollerer]

There have been many attempts to get to better A-GPS (assisted GPS)
using equipment like this one. Pseudolites 
(http://en.wikipedia.org/wiki/Pseudolite)
have been considered in research since the 1990s. The main problem (as 
Steffen
also surmises) is acceptance and market penetration.

A-GPS became successful, when the "A-" came through surveyed (google 
street-view
cars) and crowd-sourced (clandestinely recording WiFi strengths seen by 
Smartphones)
information.

More power to Locata if they think they can pull this off, but I would 
not advise to invest
too heavily in this company if this is their only approach :)

Cheers,

     Tobias
