Jamming WIFI GPS and isolating all criminal possibilities

In timing applications, wifi signal jammer can disrupt the GPS signal, causing the underlying systems to lose their ability to synchronize their internal clocks and, in turn, their ability to stay in sync with the rest of the network. Since many critical infrastructures sectors require synchronization across their network to be within millionths of a second, even short-term GPS outages can have a major impact. Worse, when an outage occurs, there’s typically nothing to indicate that it’s a result of jamming. The GPS signal simply is not received anymore.

Ch Supt Gavin Thomas, the president of the Police Superintendents’ Association of England and Wales, suggested in an interview that wifi jammers – devices worn on the ankle or wrist to block the internet – could serve as a smarter punishment for cybercrimes than prison. “We have got to stop using 19th-century punishments to deal with 21st-century crimes,” he said.

This applies to both full-spectrum jammers/scramblers and WiFi-based “rouge mitigation” tactics that disable hotspots by flooding them and their clients with deauth packets.

If you wanted a GPS signal jammer that would totally disable even SSIDs, you would destroy every WiFi network in range of the jammer along with anything else using the same spectrum (there’s quite a lot of things that use the unlicensed 2.4 and 5 GHz spectrums — including most cordless telephones).

GPS denial is a becoming a huge issue for American military planners. Peer states, especially Russia, are already putting GPS spoofing and jamming tactics to work during various training events near their own borders. We have discussed this situation in great depth before, and I would suggest you read this article to understand just how deeply the loss of reliable global positioning system data can mean for the U.S. and its allies during a time of war, as well as what is being done to overcome such a monumental hurdle.

The fact that the Department of Defense is going to execute wide-spread GPS jamming operations during such a high-end exercise is more proof of just how big of a threat these emerging electronic warfare tactics pose. It will be interesting to see if the USAF admits that the technology was indeed used for Red Flag after the exercise concludes, but considering that there are a whole number of position, navigation, and timing (PNT) technologies being developed in hopes to help overcome the loss of GPS during combat, advisories like this one that occur during major military exercises will likely become increasingly normal in the years to come.
