5/13/2023 0 Comments Rssi dbm![]() ![]() Noise is usually between -100 and -90 in normal circumstances.ĭbm is another way of expressing power (rather than milliwatts). However if the noise level is -95 then a signal of -80 will give a SNR of 15 and will be much more decodable. This means that if you have a signal at -90dbm, it's completely lost in the noise, it has a SNR of 0.Ī signal at -80dbm has a SNR of 10 in the same conditions, it is barely decodable. The noise level is usually at -90dbm let's say. On client softwares, it's usually a percentage (that has no real meaning). It does not have a precise unit of measurement. It's the strength of the signal as perceived as received by the client. RSSI means Receiver Signal Strength Indicator. ![]()
