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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Probabilistic Location Estimation -
Does it work?
Unread post Posted: Tue Mar 01, 2005 6:57 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?
