Signal Jamming

Many of the advances in modern consumer devices are enabled by the increasing use of radio signals in our daily lives. The smooth operation of these radio-based services is often taken for granted. However these services can easily be disrupted by signal jamming, whether intentionally through the operation of a signal jammer or inadvertently due to unforeseen interference from other transmissions.

Deliberate jamming, which for radio signals is the equivalent of an Internet denial of service attack, has traditionally been a military capability typically involving the deployment of specialist personnel and systems to conduct electronic warfare in support of military operations. However the cost and size of jamming equipment has fallen, and the technology can now be openly purchased online by the public. For those with modest technical skills, there are a number of websites which describe in detail how to build jammers and provide detailed designs. Deliberate jamming is no longer the specialist preserve of the military and is now available to anyone who chooses to buy or build a signal jammer.
