Sensitivity Of Reciever


SENSITIVITY

.





Sensitivity is the minimum receiving power required by the receiver to establish a reliable link having a minimum specified SNR. Signals below the sensitivity level will not establish the radio link and the noise above sensitivity level will cause interference with the usable signals and may cause fluctuation in usable signals.
If we say that the receiver sensitivity is -80dbm it means that the minimum signal strength required for link establishment is -80dbm , but at -80dbm fade margin will be zero so link will not be reliable for any fluctuation , for link to remain established the signal strength should not fall below -80dbm.
