adaptive frequency agility (AFA)

Adaptive Frequency Agility (AFA) is a transmission technique used in radio systems such as Short Range Devices (SRD) in combination with Listen Before Talking

(LBT). Frequency agility is used when a transceiver cannot transmit a signal because the transmit frequency is permanently blocked. Thanks to adaptive frequency agility, the transceiver can switch to another, free transmission frequency and transmit the signal on it.
