This is a project which helps network administrator to collect signal/noice-rate statistics from Lucent Wireless AccessPoint devices via SNMP, store it into MySQL database and view summary graphs via CGI-module.
SNR measures the ratio between the usable video signal and noise or interference.
The ratio of a wanted signal to the background interfering signal or noise, measured in dBs. SINR (I is Interference) is similar.
A communications figure of merit that is equal to the relative power of a communication signal level to the noise level. As SNR decreases for a communication channel, it becomes more difficult to distinguish between information and non-information (noise) and data throughput drops.
Signal to Noise Ration
The ratio of the magnitude of a signal to that of the noise (interference), often expressed in decibels.
Signal Noise Recognition.
Signal to Noise Ratio
difference in strength between the signal we want to receive and the background noise (or any unwanted signal).
The amount of power, measured in decibels (dB), by which a signal exceeds the amount of channel noise at the same point of transmission. It provides an indication of the clarity or accuracy with which communication can take place.
