 Post subject: Probabilistic Location Estimation - Does it work?
Posted: Tue Mar 01, 2005 6:53 pm 
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? :idea:

Thanks,
Jerry Roberts

the DAt's just come through, that supported evidence won't be used until significant portions of a user base, decide their landlines have become obsolete.
Remember that if you need making descisions for skeptics, advise the immigrants first, and the operators @nd.
It's like channelling un-supported material in the wind, so why should a Tag identify locations which don't even exist?
when you have such false rumours bought to light, there's always a clammer for more.
It's rather like feeding Zoo-animals.
