Hi all,
meanwhile I figured out that RSSI is a relative value which, in theory, can have values between 0..255. Most manufacturer define a RSSI_Max value of 100 (e.g. Cisco), but some do use other values (e.g. 0..60: Atheros).
I’m using a USB300 stick which hopefully uses the range 0..100. I have no other values identified yet, but I cannot find any documentation about that topic.
Based on my assumption, I use the RSSI value also as percent indication and calculate via rule the related dBm value (just for fun and making sure, I figured the right things out). The formula is quite easy, because I assume a linear interpolation:
dBm = (RSSI / 2) -100Hope that helps someone here.
Kind regards,
Ralf
