[4eyes] Indoor location tracking

[Saiph Savage]

I think its just using the same frequency as wifi, not the 802.11 protocol.
Considering its an unlicensed band I’m kind of surprised it can operate as
far as it says it can.  I would think it would have to stick to pretty low
power.  I bet that those boxes would have to have a pretty accurate clock if
they are using the GPS-like time of flight method of positioning, so
probably you couldn’t use just a re-purposed router.



I think it won’t replace, like the xbox kinect or other motion tracking
stuff, unless it becomes more accurate.  I would think it would be useful
for things like gps indoors where it’s usually blocked.
