Depending on the mode of operation, suppliers can operate on different frequencies.Sticks on the steering wheel locks on the pedals, multiple locks on the gearbox, sirens.Used to interfere with the working frequency of mobile operators.The equipment on the car to suppress the signal works by creating radio frequency interference at the frequencies that transmit the wanted pulses.

　　Typically, for each model, professional car thieves have a set of tools and specialized equipment that will allow you to bypass the alarm and open the car.The use of a muffler makes it impossible to use a satellite system to monitor the position of the machine.The working standards of the operators also affect here.Using these signal jammer, thieves can prevent stolen vehicles from being followed.A car thief can usually get through all these defenses without a problem.


 

　　Usually, special radio equipment is used for this - a so-called repeater system, which receives the signal of the original key and transmits it to a receiving device located next to the door.Vehicle-mounted portable GPS and GLONASS jammer is a kind of device used to suppress the pulse of the satellite system.For the most part, criminals have set their sights on cars equipped with keyless entry systems, where the owner can open the doors without a key and use the start/stop button to start the engine.

　　This device is nicknamed “fishing rod“ or “suitcase“.The device is designed to make noise on the frequency at which information is transmitted by satellite.In fact, the suppression range of the satellite signal is 5-10 meters, which is more than enough for cars and buses, since the installation of the tracker is usually carried out in the passenger compartment of the car or passenger cabin.

　　The interference radius will be larger.And military intelligence agencies use more advanced silencers.Witnesses, for example, have repeatedly stated that cellphones and satellite communications suddenly disappeared on the route of the government convoy.Evidently, witnesses experienced first-hand how high-tech suppressors of satellite and cellular communications protecting the special services of the nation‘s top officials work.

　　All mufflers work in the L1 and L2 ranges. When the device is activated, all gadgets that use GPS channels to determine the location cannot receive satellite signals.Included portable jammer are included in theatres, cinemas, and offices in many countries around the world.By the way, this often leads actors astray or even forgets the lyrics.Once connected to the onboard network, the device began jamming within a 15-meter radius.The greater the noise, the less likely the communication.

　　Pulses can be transmitted in GPS and GLONASS frequency bands.Therefore, they obtained equipment that can interfere with satellites (GPS Glonass) and cellular radio transmitters (GSM).For example, the device can be used in business meetings or government meetings to prevent eavesdropping on the spot.The function of the jammer does not affect the operation of cellular communication on mobile phones.

　　We're not just talking about navigators, but also trackers and bugs.Due to the nature of the criminal activity, many car thieves are highly trained and have many tools and equipment that can help them open their cars like nuts.Car Thieves know that many cars today can be equipped with satellites, cell phones, or combination car alarms.The frequencies of these satellites are close to each other. The generation of interference is realized by a broadband generator equipped with an antenna.

　　For example, turning off cell phones in a theater with a GPS jammers can protect the performance from the loud ringing of an audience member‘s cell phone who forgot to turn it off.GPS devices are used to interfere with satellite signals.This is how car thieves use this “stick“ to steal cars.These cellular and satellite jammers are perfectly legal devices designed to eliminate communications where they are not needed.
