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. Adam

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?
