Does it work?

Hello RF Experts:
I have a question about the emerging location
systems based on RSSI measurements. Examples are: Ekahau and PanGo Networks.
My basic question is: "DO THEY REALLY WORK?"
As far as I know
RSSI is a very poor quality index and its value changes considerably
with the environment. It puzzles me the fact that the product is recommended
for indoor use only. Shouldn't be the opposite? If anything, RSSI should
be more repeatable ina LOS situation.
Any pointer to data that
support the use of RSSI for locating radio tags?
