In this attack scenario, the attacker actively transmits on the Wi-Fi channel to prevent users from transmitting or receiving data from the targeted Wi-Fi network. There are several known techniques to perform this attack - for example: the attacker may flood the Wi-Fi access point (e.g. the retransmission device) with deauthentication frames. Another method is to transmit high levels of noise on the RF band used by the Wi-Fi network.
