![]() RSSI is most common used in bridge links where on client laptops they just call it Signal.ĮIRP (Effective Isotropic Radiated Power) is the actual amount of signal leaving the antenna and is a value measured in db that is based on 3 things: Transmit Power (db), Cable Loss (db), & Antenna Gain (dbi). RSSI (Received Signal Strength Indicator) is a more common name for the Signal value meaning it is the strength that the device is hearing a specific device or signal. 55db + -95db = 40db this means you have an SNR of 40, our general rule of thumb is that any SNR above 20 is good. So to calculate your SNR value you add the Signal Value to the Noise Value and it generates a positive number that is expressed in decibels (db) ĮXAMPLE: lets say your Signal value is -55db and your Noise value is -95db. Typical environments range between -90db and -98db. NOISE is any signal (interference) that is not WiFi traffic such as cordless phones, microwaves, radar, etc.This value is measured in decibels from 0 (zero) to -120 (minus 120) now when looking at this value the closer to -120 (minus 120) is better because that means there is little to no interference.
