Experimental Evaluation of Jamming Waveforms Against WLAN Transmission From COTS Laptop

We conduct an experimental investigation into the performance of several jamming waveforms against a common off-the-shelf (COTS) laptop. The performance metric is chosen to be bit error rate within the individual WLAN packets, as opposed to the usual system throughput. The considered jamming waveforms are noise-like waveforms generated with three methods: random QAM with OFDM symbols on varying selected subcarriers; tone signals on all the pilot subcarriers; and a triangular frequency sweep. Out of all these waveforms, those targeting the pilot subcarriers had improved effectiveness, with simple tones over the pilots giving the best results.
