Most newer chipsets use 0 to 100.įrom my experience signal strength is reduced because of barriers between the transmission point and receiving point. Notes: Look at the RSSI only on an associated client Some older chipsets used RSSI from 0 to 256, or 0 to 127. A higher difference of signal to noise indicates better signal. To get a meaniful measurement of a good quality signal, you would have to subtract the noise on the line from that signal power level and consider the difference. As a general example, a good signal would be -50, a reasonable would be -75, and a bad one would be -90, while -100 would provide no service at all. For example, RSSI of -65 is better than -85. The closer the figure is to zero, the better. It is often expressed in decibels (db), or as percentage values between 1-100, and can be either a negative, or a positive value. RSSI is the relative signal strength in a wireless environment and can be measured in any unit of power. It is a measure of the power level that a RF client device is receiving from an access point, for example. RSSI (Recieved Signal Strength Indicator) is a common name for the signal strength in a wireless network environment.
