Evaluation of the Effect of Follower Jammer on the Mobile Bluetooth Network

Bluetooth wireless communication technology has spread rapidly in the past 20 years. It has made life much easier with all the devices that use Bluetooth technology around us such as mobile phones, laptops, and watches. With all the good and useful applications of Bluetooth technology, it has been used in harmful and bad ways such as cheating in an examination. In this article, parameter design considerations have been discussed for a follower jammer to interrupt a Bluetooth network, especially when it is used in unauthorized way. The effects of the follower jammer were studied and tested. The effects were calculated for time and jamming-over-signal ratio for three different distances (1, 5, and 10 m). The testing showed that the follower jammer designed was successful in disrupting the Bluetooth signal.
