Wireless alarm has the advantages of small area, easy installation and use. Its special accessories and the connection between the alarm center through a system of medium type GSM radio waves to operate. Today, offenders use jammers, called jammers, to neutralize this type of alarm.

What is interference

"Jammer" is a GSM wave and radio jammer specially used by professional thieves. Interference principle including the launch of the signal superposition equipment to such as the center of the telephone operator communication antenna signal, also includes the central alarm and transmission between the parts of the system. However, GSM jammer cannot block the use of between 433 and 868 MHZ radio frequency band signal alarm center. Therefore, there are models of radio "jammers" that inhibit these frequencies. The sale and purchase of "interference" is highly regulated in France. In principle only cinemas and prisons are allowed to use it. However, jammers can be easily traded on the Internet.

How does the jammer neutralize the wireless alarm?

The interference source blocks the transmission of GSM or radio waves. GSM jammers prevent send alerts to cell phones, and radio interference device can prevent the detector for communication between control panel and alarm system. Disruption is actually some of the flaws in wireless alerts. In fact, this communication can only be communicated with a radio frequency band with a detector and a GSM band with a central operator. Therefore, if these links are cut off, the alarm will not jump. To do this, burglars use the "interference" of both GSM and radio waves.

How to prevent interference?

When purchasing the alarm, it is important to know that some models have functions to prevent wave interference, including interference detectors. If the GSM signal drops, the detectors trigger the alarm. When using portable cell phone jammer to disable the control panel, the alarm will explain the communication does not exist, and its components to stop and an alarm via text message or phone. You can also choose to send two different frequency double frequency alerts simultaneously. In addition, the market also provides the interference model of the detectors. They have advantages that are independent of the alarm system. But, must pay attention to really neutralize a alarm system, alarm must make alarm system at the same time all the radio channel is invalid. In order to really prevent invasion, you should not communicate with others, installed in the house type of alarm clock.

This week marks the launch of the latest DroneShield product, the DroneGun portable rifle jammer, which works independently or in conjunction with DroneShield's drone detection technology to locate and eliminate potential airborne threats.

Drone sales are expected to grow exponentially in the near future, and the number and severity of the daily drone incidents continues to increase, with DroneShield launching DroneGun to deal with the malicious use of consumers and commercial drones, which would require effective countermeasures against drone intrusions. DroneShield aims to help public and private sector customers take active measures in the context of the law to guard against airborne security, security and privacy threats.

How do drone jammers work?

The jammer is designed to destroy the drone by exploding electromagnetic noise in the drone radio frequency, the drone operation and transmission of video, and the power level is sufficient to overwhelm any effective communication between the uav and the pilot. Usually, this is 2.4 Ghz or 5.8 Ghz (" RF - jamming "), which is "unallocated" public frequency, which means that the drone interference does not interfere with manned aircraft, mobile phone, public broadcasting or other specialized radio spectrum. In addition to RF interference, if the customer is legal (depending on jurisdiction, which may include military, law enforcement, first responders and private users), it can also use GPS jammer because a large number of drones rely on GPS to balance the wind, or between predetermined routes.

When a drone is hit by a jamming signal, the drone usually returns to the origin (unless the GPS is also stuck), allowing the user to track the drone to the pilot. Sometimes, unmanned aerial vehicle (uav) may occur even vertical drop, and is in good condition in site, this provides a forensic investigation of choice. Landing on site is also the general response of drones, when rf and GPS are stuck simultaneously.

Jammers can be effective against drones a few kilometers away. In general, compared with unmanned pilots, the operation of the jammer and unmanned aerial vehicles (uavs) and the distance between the drone jammer. The farther the drone on the plane, the better the interference. The typical effective distraction is a cone of about 15 to 30 degrees, protruding from the gun (which is also affected by the power of RF band and interference).

The global positioning system has achieved almost all such technological advances, and a decade ago, parents were anxious not to peer into their children's location. Today, they can monitor their location by using mobile phone jammer or their car's global positioning system spy tool. The technology, on the other hand, in addition to eliminating daily activities in the hidden side of though if you know your privacy has been severely eroded, some steps you can take to you some privacy. In order to prevent the volatility of the global positioning system (GPS) is a spy in the face of GPS technology, in the best way to regain freedom.

These tools is the important problem, in most places in the radio, the federal communications commission banned the sale of these tools when don't like the rf signal. Even though these tools can only be effective in short distances, they are still prohibited. It is similar to having radar detection tools in areas that make it illegal. Mobile phone jammers are very popular today, as well as wifi jammer and GPS.

Cellular phone jammer suppresses the if signal cannot reach the idea of global positioning system (GPS) spy tools, may contain some inaccuracies in use. When they work, they stop the spy signal by sending a stronger signal, which is disconnected from the incoming spy signal, so that the spy signal doesn't seem to work. GPS locking tools run in a small area and are effectively transported to block signals to the car's spy tools, or they can be used to block any GPS devices (such as mobile phones) in your body.

At the university of Texas at Austin radio navigation lab director subvert GPS shows his students his small workshop experimental video, these experiments desultorily all sorts of equipment. It shows the length of a mobile smart phone, the screen shows the Google map: "the device using GPS chip positioning, and shows the location of a blue dot on the map." Suddenly, the blue dot moved, as if the smartphone had just been shipped on the car, and it was still in the same place. The position of the GPS chip transmission errors but reliable, because of the progress on the map the normal speed down the street.

In order to explain the riddle, Todd humphries (subvert GPS) pointed out that in the corner of the shop an ordinary case: "this is a deceiver (" usurper"), a GPS simulator. It picks up real signals from GPS satellites and then resends them at the same wavelength after a slight modification of the coordinates. Near the GPS system will pick up the deception of false GSM jammer, because it is stronger than 20000 kilometers from earth satellites. If I have a good antenna on the roof of this building, I can twist all the GPS in the neighborhood, even the planes that cross the city. "

According to Todd Humphreys, a hacker, rogue Mafia or a terrorist malicious use of the spoiler could lead to a chain disaster, because GPS systems now play a crucial role in many industries: land, air and container management, agricultural machinery guidance, electronic communications and even banking, using satellite signals as a universal clock, and financial transactions have so far reached a hundredth of a second.

We've got a fight back. In the UK, a consortium of public and private laboratories has developed a device that can detect GPS jammers. Along the road tests, the researchers were surprised to find that they are already quite extensive, tested several times each week in a single crossing, a random sample.

In Austin, Todd humphries (GPS) is completing the development of a more sophisticated equipment, the precise positioning of GPS jammer, and allows the police seize these devices. On the other hand, he noted that the USRP (general software radio peripherals) type of new radio transmitters were highly rated by researchers and amateurs because of the coverage of all bands, and could broadcast signals on GPS frequencies. This leads to very effective interference. The war has only just begun.
