What is Receiver Sensitivity? - everything RF

WebA minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output. In practice, m is usually chosen to be greater than unity. In some literature, the name … WebApr 8, 2024 · The EIRP is calculated as follows: EIRP = 1 - 2 + 3. RSSI: signifies the signal strength at a location in the coverage area of a wireless network. It is the value of the EIRP minus the transmission path loss and signal attenuation caused by obstacles. Weak signal strength means that the RSSI is lower that the edge field strength.

WebSNR (dB) = P received_signal (dBm) - P noise (dBm) SNR (dB) = -120 dBm - (-90 dBm) = -30 dB The negative SNR means that the signal power is less than the noise power. The value of -30 dB is below the minimum SNR of -20 dBm @ SF12, so it does not guarantee that the receiver will be able to demodulate the signal.
