Hello to everyone, I am a researcher working on WSN, using IRIS motes (which use RF230 Radio Hardware). I am measuring the received power from one mote to another. The RF230 datasheet says that two different measures can be used, Energie Detection (ED) or Received Signal Strength Indicator (RSSI). To convert the measured values to dBm, according to the datasheet, for the first case it is necessary to do: PRF = ED_VAL -91. For the second case the following has to be done PRF = RSSI_BASE_VAL + 3•(RSSI - 1). The problem is that these measures does not seem to be equivalent since using the ED measure I receive more power( a difference greater than 10 dB) in comparisson with the RSSI measure. I am using the Basic operating mode so, since what I know, both measures should be very similar.
I would appreciate any help, Best Regards _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
