Bomb and Frequency Jamming Introduction

The principle of 'Jamming', in essence, is to disrupt remote signals being transmitted to a receiver. There are various applications for such, and equipment varies dependant on the target application and distance of 'Jamming' required.

Typical Objectives of Frequency Jamming:

• Preventing acoustic disturbance caused by mobile phone ring or conversation;
• Enforcing policy due to institution security/safety concerns;
• Prevention of remote detonation of Improvised Explosive Devices (IEDs)/Bombs.

What is Bomb Jamming?

Bomb Jamming is a technique used to disrupt signals being transmitted to a receiver connected to an Improvised Explosive Device (IED)

• RF IEDs or Radio Frequency Improvised Explosive Devices are popular weapons of insurgent and terrorist groups;
• Bomb Jammers blanket areas with radio interference, neutralizing radio controlled improvised explosive devices;
• They defend the users from criminal acts such as car bombings, assassinations, border control and check point bombings, roadside bombs, and other forms of terrorism;
• They also can provide protection to public areas such as shopping centres, civil & religious gatherings and public transport;
• The Bomb Jammer covers frequencies well beyond normal cell phone jammers and cell phone jammer technology in order to combat all RF threats, not just cellular activated weapons.

The effectiveness of Jamming varies with the following factors:

• The terrain & buildings;
• The weather conditions, atmospheric pressure;
• The frequency of the target;
• The location of the Jammer - carried or vehicle mounted;
• The power level of the command transmitter.

Vehicle Jamming

Vehicle mounted modular radio signal jamming systems are designed for defensive jamming of radio controlled improvised explosive devices (RCIEDs) used as weapons by terrorists, assassins, and criminals.

Systems can be designed to be mounted in a single vehicle, or transferable to alternate vehicles.

In combat zones or areas of civilian unrest, emitting a protective shield of electro-magnetic energy increase the chances of survival and decreases the threat of terror attack with a remote controlled improvised explosive device (RCIED).

Convoy Jamming Systems

Convoy Jamming Systems are used to counter IED attacks by terrorists or insurgents planning an unmanned ambush on convoys. This type of ambush can take place on a crowded street or in the middle of a desert.

Countering a Remote Controlled IED assault on a convoy requires a specialist Convoy Jamming Systems designed to defend groups of vehicles against explosives and mines that are all detonated by remote control.

This system consists of a configuration of Jamming modules that emit radio interference from various vehicles within the convoy. This interference is essentially a series of multiple RF Jamming signals that are transmitted at high speed and envelope any radio receiver within their area of affectivity.

V.I.P. Portable Jamming

Portable RF Jammers are typically a hand held frequency Bomb Jammer built into a briefcase.

Using Westminster's portable RF Jammers gives the user the edge when trying to avoid an attack from a Remote Controlled IED.
