CCA is 802.11 standard abbreviation of "clear channel assessment". Simplistically, CCA threshold is the signal level above which receiver assumes that the channel is busy. Mainly affects the Tx procedure. ANI stands for Automatic Noise Immunity. ANI is a software driven method for controlling radio sensitivity in the face of noise sources [1]. > > I need to create this algorithm but do not know where to start > help me, we will develop this tool running in the system RouterBoard > mikrotik well. Sensitivity is too general term. What exactly do you want to control? 1. https://wiki.freebsd.org/dev/ath_hal(4)/AutomaticNoiseImmunity -- BR, Sergey
