Measures against reconnaissance and intelligence radio interference

Smartphone radio wave blocking In the information age, communication technology for high-speed development, mobile phone has become an important and indispensable tool for people’s daily work and life. However, this brings various advantages.

The proliferation of mobile phones cannot be ignored. I’m creating some issues. Various problems are getting serious with mobile phones. The development of science and technology, mobile phone location tracking and surveillance has become the most important means of reconnaissance and intelligence sources in the world. Therefore, as long as you use it or not, it will be caused by a leak, in a voyeur detection machine, as long as you have a cell phone in a secret location, most likely a unit or individual, a country that also has serious harm to political parties.

All the latest patch elements and integrated circuits, such as cell phone signal jammer, advanced performance, easy installation, long time continuous operation. We have developed a deterrent device that can effectively deal with the problem of mobile phone signal jamming. Countermeasures against radio wave interference Security information such as electric fence networks, new products with specific electromagnetic signals at loci that should protect base stations so that mobile phones cannot receive data is transferred from the security roll to mobile phones. It is not possible to eliminate the negative effects generated by and establish a connection with the base station. Telephone signal jammer will be your loyal defender you can trust and provide a safe and quiet space!

Location of use: Prohibit the use of mobile phones in government, military, finance, securities, prisons, commercial vehicles gps countermeasures public safety command centers, or anywhere. Phone signal jammer has the effect for mobile communication only, without interfering with other harmless electronic devices, and can be widely applied.

Handy blocker keeps your location secret

If you have never used a jammer before, it is important to emphasize that this device should cut the signals from GPS devices. The gps signal jammer perfectly blocks the transmission of GPS signals and gps so that gps devices cannot recognize your specific location.

The type and model of GPS jammer have different technical specifications, so we recommend that you carefully study technical functions before buying. Each cell phone jammer has a different blocking radius, which is positive from 5 to 100 meters. Nearby GPS devices will work fine. Furthermore, GPS blockers are equipped with a rechargeable battery and when fully charged you can use it for a long time Use time without a stop.

Popular type mobile jammer

A good environment for important meetings requires a mobile jammer.

We are tired of being suspended, especially in important places, and I’m tired of cell phone rings. He was very angry when the leader presided over an important conference and was disturbed by the ringing of a cell phone. In order for the conference to maintain a good environment, cell phone jammer is used in the conference room.

Cell phone ringtones make people more tired, especially in some quiet public places. In many places, the widespread use of mobile phones has banned the use of mobile phones, and as they are using it would affect others to rest or work that would affect others. There are also clear instructions for banning the use of mobile phones, such as gas stations, but the slowing effect of mobile phones affects sites such as the use of equipment, but many Located in these places where people use We use mobiles at gas stations is dangerous and there is a high risk of explosion.

We need to keep the content of the meeting confidential. You need to know that the country’s important conferences will last for days, and cell phones are banned, so you can’t interrupt the outside world. It’s not just a national conference, it’s also adopted by numerous corporate conferences, including banning mobile phones and gradually installing mobile phone blockers.

Cell phones are banned at gas stations, but many public places are beginning to ban them. Cell Phone Anti-Junk Device may also be banned in some private places. We have heard about the use of cell phone jammers and the use of cell phone jammers in schools, so many companies are increasing their reliance on cell phones, so many companies have a room for adjustable devices in meeting rooms. Is starting to install. The cell phone jammer is held the conference leader during the conference to make the conference and order, open and adjust the range of interference in the conference room without interference by ringtone. This does not affect normal outside use only, but also provide a meeting environment.

If a cell phone ring interrupts a speaker’s thoughts in an important meeting, it distracts participants from the meeting, confusing him. The cell phone in the conference room with the important bell ringing is rude behavior, so in many of the previous meetings, the use of cell phones in the increasingly mobile era of the Internet era, increasingly clear regulations are prohibited.

If you are part of a meeting, how do you feel listening to your cell phone ringing frequently during the meeting? I think you would be as angry as I’m unhappy with this behaviour, even scolding the phone owner. This is not an unfortunate ending, but we avoid this unpleasant consequence. What you want to see, a conference room that uses a cell phone jammer is very necessary to use it in a conference room, you can refer to the above and many advantages like banning barren phenomena We have not only banned mobile phone ringtones, but banned use of mobile phones during that period.

If you are a boss, you need to have meetings, meetings always have someone ring your phone or have a look at your phone, prohibit the use of your phone by installing a mobile signal jammer device can do. It can now be purchased from us.

Story of drone and mobile phone jammer on NHK News

Knowledge of drone and 4G phone jammer week frequency

By Wikipedia’s explanation, FPV (first person view) is called RPV (remote person angle) or video navigation. It is a backpass facility with a built-in wireless camera based on a remote-controlled model airplane or car model, which is a new way of playing the model on the ground while watching the screen. Over the last few years, more and more people are using drones. This type of FPV utilization is most often seen.
The drone is actually a pilot’s eyepiece surveillance, a higher version of the drone incorporates two in-vehicle cameras and a portable jammer 4g in the pilot’s eyepiece. Can be 3D view

Cell Phone Frequency Jammer

Wi-Fi Radio Blocker Let’s study basic knowledge about week frequency

2.4GHz and 5.8GHz are the two most common frequencies for being connected to terrestrial radio transmitters and UAVs. The 2.4 GHz band is a common radio frequency. Often used to connect to ground-based transmitter axis aircraft and UAVs. If you know more about frequencies, you may know that the 2.4GHz band of unwanted cell phone jammer is also used in wireless computer networks. Therefore, it can be expected that there will be many accidents that lost control of the aircraft in densely populated residential areas with too many radio signals.

Another problem with drones is that they interfere with the vehicle’s navigation system. This is mainly due to the fact that the two transmitters worked together, one transmitting the guided wave number signal to the vehicle and the other transmitting the video signal to the driver.

The 5.8GHz band is used in 4-axis aircraft technology to avoid entanglement of the same frequency band with other RFs. This weekly wave number is found in the Dow Phantom model. Let’s see how UAVs work around wireless frequency issues

Phantom 1 This drone works in the 2.4GHz band. If you plan to participate in FPV, you will have to do it yourself using the 5.8 GHz frequency of the mobile deterrent jammer to avoid common problems.

If you use GOPRO or any other action camera’s unique wireless system, remember that the wireless option is turned off. Otherwise, it could interfere with the aircraft. The Phantom FC40 drone has adopted a radio frequency of 5.8 GHz. And since it has a single 3.4GHz system, you can send videos and photos to your pilot.

Phantom 2 Because this drone uses control at a 2.4 GHz radio frequency of a drone jammer , you have to use additional tools. So we use the 5.8 GHz frequency to carry the FPV signal.

Phantom 2 Vision and Vision+ These two types of drones use 5.8 GHz and 2.4 GHz FPVs separately and utilize smartphone application connectivity and telemetry.

Portable jammer final conclusion

Therefore, if you bought a phantom UAV without a camera and other drones, you should use the 5.8 GHz frequency and FPV. By the way, it is worth noting that the RF signal is said to be a LOS mobile jammer or visual signal line. If there is no barrier between the UAV and the remote control, it will show that they cannot work. The best flying area of the drone is directly visible to the naked eye. Otherwise, you could damage or lose your drones.

Canadian high school principals try to use cell phone jammer

Principal Steve Gray of Port Hardy Secondary School on Vancouver Island, who bought the signal jammer from an online vendor in China, said he had to prove something since children were still using their phones despite the cell phone ban at school.

While the experiment was short-lived, the controversy speaks to the growing problem in schools, especially high schools, of the rampant use of cell phones during school hours.

Donnelly also notes that controlling devices is important because they can be a mechanism for everything from cyber bullying to passing responses to a test.

So the problem is not only educating children about the proper use of cell phones and other technological devices, but also about making sure parents understand the rules at their children’s school, she said.

Why use the gsm jammer?

“We note what we perceive as a growing negative impact of cell phone use on student learning and particularly on student engagement,” said Steve Gough, principal at Comstock Park High School. “Cell phones can be a powerful tool to help people access information, but they can also be a powerful distraction.”

College students are quite optimistic about using smartphones and laptops in class and believe that they can aid learning and are critical to their safety, so they should be left at all times. And when a cell phone rings in class, students prefer to be ignored by instructors, joyfully wielding it through humor, or talking to the student privately after class. In contrast, most of the interviewed US teachers had specific rules in their curricula for using all digital devices in class with penalties for rule violations2. Surprisingly popular were the outright bans on student phones and laptops.

Too many students use their cell phones to talk, visit, and verify what is taught in the classroom. We need to correct this now. Cell phones can be a great learning tool, but parents must set the law on how and when to use them.

Officials at the United States Department of State are still trying other ways to fix the cell phone problem. DOC is working with a Maryland-based company on a $ 1.5 million contract to install a system that “allows authorized calls to pass but blocks others in a precisely defined target area.” That system will be installed at the end of the month.

If cell phone jammer is not properly regulated, similar to bi-directional amplifiers (BDAs), we will experience a more severe uncontrollable disorder that has led the industry to pursue the overabundance of interfering signals emitted by FCC approved devices. It’s easy to inadvertently create a blocker. Rotate the gain control to the maximum on both the uplink and downlink amplifier and disregard the isolation between the redistribution antenna system and the donor. The level of white noise generated by this device is at least as damaging and dangerous to public safety radio systems as any interference device designed so far. Typically, BDAs are installed without proper supervision and maximum gain is used to provide the most coverage, while this two-way amplifier is unknowingly nothing more than a broadband generator radiating to an outside antenna.

Your car is spying on you

The history of the car is glorious. The invention of the wheel was certainly a step in the right direction. But when the car was invented at the turn of the century, no one knew what the capabilities of the mobile device would be. Not only has it become one of the most reliable forms of transportation, it has become a man’s best friend. The car is a status symbol, and the functionality of the car is an indicator of the livelihood of the person driving it. What people didn’t realize is the fact that one day it would become the subject of much controversy regarding privacy.

While the invention of GPS was an important step in security and tracking, GPS-equipped cars could be doing a little more. They are elegant and smart, and many people prefer and feel more secure in them. However, recent revelations seem to indicate that the GPS device may be a little smarter than most of us think. According to experts in automotive technology, the fact that one knows exactly where the person is driving at any given time could have enormous potential. One may be able to manipulate that information to acquire and sell personal information. Selling personal information has the potential to make someone earn money. Cars track people in the same way that smartphones do today. The instances of using smartphones to obtain personal information are not new.

Targeted advertising services and marketing make it more lucrative. This is the reason why there is greater political will to try to stop this growing trend. Senator Chuck Schumer of New York is leading the demand for federal regulations to control any potential violation of privacy. According to the senator, GPS devices, black boxes, and vehicle-to-vehicle devices collect a lot of information that vehicle manufacturers can collect and sell. It calls on relevant organizations, the national road safety administration and the federal trade commission to establish clear guidelines on the type of data these devices can collect. Their suggestions also go as far as giving drivers the option to opt out of such programs that collect your personal information.

There is some truth to these allegations of espionage and information gathering. If the car tracks where the individual is going, then he knows the person’s favorite places. Track and record all movement so you know where the person unwinds during their free time, where they eat, and who they visit. Auto Tracking even knows people’s favorite vacation destinations. But do car companies share this information? In his justification, Senator Schumer cites a study by the government’s accountability office. It reveals that up to 90 percent of automakers, security and tracking devices share the information they collect. And in this case, it would be wise to use a 10-frequency gps jammer because car eavesdropping is a troubling trend, and the fact that it takes advantage of devices that people trust to keep them safe makes it even worse.

Jammers of drones and quadrocopters

The digital revolution pervades all areas of our lives. Unmanned aerial vehicles (drones and quadrocopters) are gaining popularity and become more autonomous. It is becoming increasingly difficult to defend against unauthorized invasion of privacy. For example, it is very difficult to protect yourself from unauthorized aerial shots that can be carried out with the help of “drones”.

First, for the purpose of controlling unmanned aerial vehicles, 2.4-5.8 GHz WiFi communication was used. Now, radio frequencies of various ranges and even satellite communications are often used. Video equipment is installed on the drone, and it is capable of transmitting everything to the camera’s lens “to the base”. How do you like it if you don’t know who owns a drone or a quadrocopter will circle over your lawn? Or will someone use these devices to shoot a production facility that you own, with locations for hidden security posts and video surveillance systems? Are you ready to share your work secrets?

Drones in the hands of attackers can cause you real damage. Already no one can guarantee you privacy. However, there is one remedy. Devices that interfere with the transmission of audio and video signals – drone jammer. As drones improve, these devices also become more technically sophisticated and powerful enough to carry out the corresponding tasks.

Below we will give you some recommendations for choosing such a “jammer”. The main indicator of the effectiveness of such a device is the spectrum of blocked frequencies. The frequencies used by drones to transmit signals to a control station can be classified as follows:

frequency range for video transmission: 2.4G WIFI 2400-2500 MHz 20 W;
frequency range used for remote transmission of control commands: 2.4G WIFI 2400-2500 MHz 20 W;
frequency range for video signal transmission and remote transmission of radio control commands: 5.8G 5.5-5.9 MHz 2 W;
frequency range of remote transmission of radio control commands (868-912 MHz, 860-920 MHz 25 W, 433-434 MHz 20 W);
Additional GPS frequencies L1 1575 MHz 40 watts.

At the output, such a “signal jammer” is capable of delivering power up to 127 watts. Six 0.5-meter fiberglass whip antennas provide an effective 360-degree coverage area.

The effective range of the “jammer” is 200-800 meters. The impact power varies depending on the signal strength and the distance of the drone from the “base”. Reliable cooling system (built-in chillers: 5 small internal versions and 3 larger ones – from the top above) ensures a silent and reliable operation of the device. A peripheral network device (in the execution from 50 to 60 Hz, from 100 to 240 V AC (AC100-240 V-DC24-27 V) will be able to ensure the effective operation of your “drone suppressor” around the clock.

Cell Phone Signal Jammers Can Be Used In Your Office
