RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Probabilistic Location Estimation - Does it work? - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

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.
