Jammers: Frontline Weapons to Intercept "Dialer Bombs"

Improvised explosive devices (IEDs) have become a frequent attack tool used by terrorists and insurgents in modern conflicts, especially in war-torn areas. These bombs are remotely detonated via mobile phones and other wireless devices, making them an unpredictable threat. By connecting the explosive device to a mobile phone, terrorists use the phone's call or text message function to trigger the electric detonator, thereby detonating the explosive. cell phone jammer This technology, known as "dial bombs", has been successful in insurgent activities and has posed a huge challenge to the military and peacekeeping forces.signal jammer

The deadly threat of mobile phone remote control IEDs

The reason why "dial bombs" are so powerful is mainly reflected in their terrifying detonation method and the materials used to make them. GPS jammer Terrorists often use large-caliber artillery shells loaded with large amounts of TNT explosives to make bombs. The power of this device is so amazing that even armored vehicles and main battle tanks cannot withstand it.Wifi jammer Both Israel's Merkava tanks and Saudi Arabia's M1A2 main battle tanks have been attacked by IEDs, and the impact of the explosion can even blow the tank turrets dozens of meters away.

The operating principle of these remote-controlled bombs is relatively simple. Terrorists usually remove the speaker or vibration motor in the mobile phone and connect it to the electric detonator. When someone calls the mobile phone, the current flows through the wire, triggering the detonator to detonate the explosives. Although this method is simple, it has serious flaws: any incoming call will detonate the bomb, increasing uncertainty and uncontrollability. Therefore, when choosing a mobile phone, terrorists often use devices that can set whitelists and blacklists to avoid accidental detonation. A more advanced approach is to modify the mobile phone software so that it will only detonate when a specific text message is received, thereby improving security.

Military response strategy

Faced with this high-frequency threat, the military has continuously upgraded its defense measures. In order to reduce casualties caused by IEDs, the US military has increased the protection capabilities of tanks and armored vehicles, developed mine-resistant personnel carriers with V-shaped explosion-proof chassis, and used helicopters and tanks to clear suspicious areas before operations. However, these measures failed to completely solve the problem, and the military urgently needs more effective electronic countermeasures technology.

To this end, IED jammers came into being, specifically used to counter bombs triggered by radio signals. These jammers prevent bombs from being detonated within a safe range by transmitting jamming signals to cut off radio communications between remote control devices and bombs. Initially, jammers were used by bomb disposal teams to prevent enemies from detonating bombs during bomb disposal.
