Portable jammer prevents remote initiation of a radio-controlled bomb
A portable jammer connected to a pop-up tent creates an instant protective faraday cage to prevent the remote initiation of a radio controlled bomb.
Electronic counter measures (ECM) specialists at Kirintec have been working on a range of novel ways to get their jammers closer to a suspect device so that they can focus small amounts of power on blocking out the signal which will detonate it.
The latest addition to their REBUS counter-IED inhibition system is a self-erecting enclosure.
The REBUS counter-IED inhibition system is designed primarily for use by first responders who find a suspect device and want to neutralize the threat while they wait for the Bomb Squad or ECM team to arrive.
Designed with non-ECM-specialist security staff in mind, the low power jammer is very simple to operate and requires no training.
Bomb disposal technicians can then x-ray through the flimsy tent wall, and if need be fire a disruptor through it.
Meanwhile, all normal communications in the near vicinity remain unaffected by the jammer (e.g. walkie-talkies, UHF, VHF or TETRA radios, air traffic control systems , company wireless networks, and public cell phone networks).
All jammers need an antenna to radiate their power. An enclosure with a layer of electromagnetic screening fabric and an antenna embedded into it creates a perfect faraday cage for both transmitting the jammer signal and retaining it within the enclosure.
A double benefit is that the enclosure also prevents the jammer from disrupting the radio spectrum outside it, or causing costly cell phone network downtime.
The REBUS jammer uses a new technology to focus a small amount of power across a wide spectrum, simultaneously covering all the typical frequencies used by terrorist bomb-makers such as 3G and GSM mobile phones.
The inspiration for the enclosure came from a weekend at The Big Chill music festival. The small, lightweight, pop-up tents so popular with festival-goers are an ideal frame for the jammer antenna.
Kirintec’s tent has been sized deliberately to sit easily over an average sized suitcase without touching it. The frame is flexible enough to slide it into position in a range of awkward locations. And it flat-packs for easy storage.
Other antenna outputs for the REBUS jammer are a blast suppression blanket, a blast suppression bin, and a large tarpaulin for covering suspect vehicles along the route for a VIP.
Kirintec’s C-IED jammer system is already in use by police forces in six countries, with a further 15 countries currently conducting trials. Primary interest is from police units whose job it is to protect the general public in normally crowded places which are difficult or costly to evacuate such as mass transit centres, major tourist attractions or event venues.
