“…Jamming Attacks about frequency synchronization deviate OFDM subcarriers offset from normal orthogonality, resulting in inter-channel interference and SNR degradation for receiver devices. Zhao et al [10] disabled the communication of an 802.11ax device with unaligned jamming using 25% of the entire bandwidth. La Pan et al [11] proposed the preamble phase warping attack which used the frequency shifted version of the preamble differential scrambling attack, they also introduced differential scrambling attack, targeting coarse frequency correction to disturb the periodic frequency pattern of received preamble.…”

In some specific confidential occasions where Wi-Fi communication needs to be completely disabled, the interference device needs to meet the requirements of energy saving, portability, and long-distance interference. Motivated by this issue, we present and evaluate Legacy Short Training Field (L-STF) jamming attack, whereby a sender device determines the channel busy despite good channel conditions. In an L-STF attack, the attacker can generate L-STF signals and send signals continuously on the target channel. We implement the L-STF jamming attack on an SDR platform and evaluate the effectiveness through PSR metrics, we also test the energy efficiency on six Wi-Fi devices from different manufacturers. The result shows that sending L-STF signals within a fixed time interval under appropriate transmit power can disable Wi-Fi communication between devices. For all tested Wi-Fi devices, the attacker can disturb communication when jammer signals are about 40 times weaker than the legitimate signals. Together, L-STF jamming can block Wi-Fi communication effectively and energy-efficiently with simple software and hardware requirements.

“…In [54], Shahriar et al argued that, under off-tone jamming attacks, the orthogonality of subcarriers in an OFDM system would be destroyed. This idea has been used in [55], where the jammer takes down 802.11ax communications by using 20-25% of the entire bandwidth to send an unaligned jamming signal. In Wi-Fi communications,…”

Wireless networks are a key component of the telecommunications infrastructure in our society, and wireless services become increasingly important as the applications of wireless devices have penetrated every aspect of our lives. Although wireless technologies have significantly advanced in the past decades, most wireless networks are still vulnerable to radio jamming attacks due to the openness nature of wireless channels, and the progress in the design of jamming-resistant wireless networking systems remains limited. This stagnation can be attributed to the lack of practical physical-layer wireless technologies that can efficiently decode data packets in the presence of jamming attacks. This article surveys existing jamming attacks and anti-jamming strategies in wireless local area networks (WLANs), cellular networks, cognitive radio networks (CRNs), ZigBee networks, Bluetooth networks, vehicular networks, LoRa networks, RFID networks, and GPS system, with the objective of offering a comprehensive knowledge landscape of existing jamming/anti-jamming strategies and stimulating more research efforts to secure wireless networks against jamming attacks. Different from prior survey papers, this article conducts a comprehensive, in-depth review on jamming and anti-jamming strategies, casting insights on the design of jamming-resilient wireless networking systems. An outlook on promising antijamming techniques is offered at the end of this article to delineate important research directions.
