You have to reduce signal strength to increase variation in your studies. Also, if you go outside, there are high chances that the area under which RSSI power remains same would increase as there is a little more noise in inside atmosphere as compare to outside.
Please correct me if I am wrong.
Good Luck

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!
