Probabilistic Location Estimation - Does it work? - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

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?
