Bluetooth Low-Energy Beacon Resistance to Jamming Attack
Volodymyr Sokolov, Pavlo M. Skladannyi, Volodymyr Astapenya · 2023
To assess the potential damage from jamming attacks on a Bluetooth Low-Energy (BLE) Beacon device, an experimental setup with a packet emitter, sniffer, and signal spectrum control at the receiving point was used. With less than 0.7% of successfully delivered packets, it is impossible to talk about the success of even non-critical equipment. From the ratio of single-error packets to lost packets rate, it can be seen that the tipping point occurs on the chart at minus 12 dBm for a 2 Mb/s baud rate. An increase in the level of the interference signal may be invisible to the user until a certain point when the number of errors in the system begins to increase like an avalanche. This results in an increase in lost packets and the generation of new traffic due to retransmissions. However the additional traffic is also subject to interference, so the useful data rate is reduced even more. It should be noted that for low transmission rates, the single-error packets to lost packets rate is constant.
