Hi,
I have just finished a project where i was measuring RSSI values in an
indoor enviroment in every 20cm-s. I can send you a few figures if you
are interested. Several effects cause those weird RSSI characteristics
like interferences, etc. The characteristics are not really monoton in
my study after 100 cm.

Hi!(TinyOS 1.x)

I´m trying to do RSSI indoor ranging using the Pong
application to measure the ping and pong message
strengths..
I´m varying the distance between the motes every time
to 0.5 m more and measure 100 times, then calculate
the Average.

Now, the problem is that it does not vary slightly!!
there is a difference between 50 cm and 5 meter but
there is no big difference, or even no difference
between the 2 3 or 4 meters. Is this due to the indoor
environment and its constraints?

Which is the best distance difference i shoul use to
get good results? which Distances should i use when
measuring?

Thanks in advance!
