Perhaps look into something like the Loc8tor http://www.loc8tor.com/uk/primary-products/loc8tor-plus-pack.html

I am not well-versed in this technology, but am wondering what would be needed to make a portable tracking system – locating a tag (keyring type) in a building where no readers have been placed or mapped in advance. A picture of people searching for treasures on the beach with large metal detectors flashes in my mind, though for this RFID locating system one would wish something more discrete. Any ideas?

>With L-RX300 solution the tags L-TG100 or L-T800 how long the battery work?

Not something I can really verify at the moment as I have not had mine running that long.

>Do you buy with motion dectect or normal?.

I purchased the non movement detection versions.

Good luck with your project.

Sorry for language.
In your project you start with principle of Trilateration, but you change because it is not precision, in the document is described how increase the precision with Trilateration.

With L-RX300 solution the tags L-TG100 or L-T800 how long the battery work?. 5 years like the technical document or less. Do you buy with motion dectect or normal?.

I bought 3 tags and 2 L-RX300 to make some test, I have a home with automation of Bticino with many IR sensor for alarm system and home automation, but i like to increase the automation with rtls system, I ask to Ekahau system but it’s vary expensive for home.

I do not speak Italian / not sure how relevant it is specifically to the Synapse modules, but thanks for the link.

To increase the precision with rssi I find this document:

I purchased the “Wavetrend L-RX300″ reader, tags really depend on what form factor you are looking for. I tested the L-TG100 and L-TG800.

What wavetrend parts would you suggest to replicate the synapse parts you used?

I did not do any multi-floor unfortunately, but you raise a valid point.

In terms of battery life / other issues such as ease of production I have now been looking into some alternate hardware commercially produced by WaveTrend. I would suggest considering WaveTrend tags/serial readers, some suppliers are:

http://www.aeroscout.be/contents/en-uk/d140_Wavetrend.html
http://www.upswung.com/Wavetrend/Wavetrend_readers.htm

The protocol is serial so it is a fairly easy process to integrate with the readers, and they also provide signal strength.
