What is AFH (Adaptive Frequency Hopping)?

Adaptive frequency hopping (AFH) implies that the conveying devices are constantly observing their environment for impedance, and they are persistently changing the channel map as per the interference. For instance; Adaptive Frequency Hopping permits Bluetooth to adapt to the environment by distinguishing fixed sources of impedance and barring them from the list of available channels. This process of re-mapping additionally includes decreasing the quantity of channels to be utilized by Bluetooth.
