What is Signal-to-Noise Ratio (SNR)?
A. SNR is an electrical engineering concept defined as the ratio of a given transmitted signal to the background noise of the transmission media. It is widely used in the wireless environment and usually referred to as a power ration between a signal and background noise. SNR = P(Signal)/P(Noise) SNRs are usually expressed in terms of the logarithmic decibel scale. In decibels, the SNR is 20 times the base-10 logarithm of the amplitude ratio, or 10 times the logarithm of the power ratio. Q. Should I use the dynamic control features of Radio Resource Management (RRM) like Dynamic Channel Assignment (DCA) and Transmit Power Control (TPC) or should I use the static values that are given to me from a site survey? Does a problem occur if I use VoIP on wireless with the dynamic method (RRM)? A. Typically, RRM focuses on power levels more than channel selection. It is very rare for RRM to change the channel of access points (APs) once all of the APs are deployed. However, it can react to neig
