Mobile phone blocker is a mobile phone blocking program or mobile phone detection system, designed to prevent unauthorized mobile phones while allowing authorized mobile phones to run. Blocking cell phone signals can prevent certain critical foundations, unauthorized calls to courts, military installations, or certain environments that need to manage cell phone activity to control the control.

Please note that in some states, cell phone jammers are illegal. Although attention to information rejection has long been an integral part of the PLA’s doctrine, this jammer is mainly used in military locations or other places where the use of mobile phones is prohibited.

Anti-drone technology: what they do and how they work

Audio detection – drones emit a very specific sound. There are devices that can listen to the very specific frequencies of the whirring devices and work well up to a point. In a quiet, pastoral setting, these devices can detect an approaching drone with an accuracy of up to 500 feet. In a study conducted by Korean researchers and published in January 2017, these devices were tested in a real urban environment. When used in a noisy environment, audio detectors struggled to more accurately identify the incoming drones.

RF Technology – Drones use radio frequency to communicate with their operators. To keep the receiver and the transmission connected, they are paired with specific RFID chips that prevent other devices on the same frequency from overtaking the drone.

Jammers – Jammers emit electromagnetic noise using the radio frequencies that drones operate on and output information. In fact, they drown out the conversation between a drone and its operator. This is usually either 2.4 GHz or 5.8 GHz, which are unassigned public frequencies. This prevents jammers from interfering with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands. drone signal jammer can be either stationary, mounted devices or built into highly mobile, gun-like devices that can result in a drone landing safely on the ground from where it may have intended.

Geofencing – Geofencing creates a barrier that surrounds airspace using a combination of a GPS network and Local Radio Frequency Identifier (LRFID) connections such as Bluetooth or Wi-Fi. This boundary is created using a combination of hardware and software to create a physical and invisible boundary that surrounds an airspace. Some drone manufacturers incorporate geofencing technology into their aircraft to warn pilots when they enter no-fly zones or restricted airspaces such as prisons, power plants, or airfields.

Video Detection – Video can be used in conjunction with other drone detection technologies to create and relay a visual record of a detected drone incident. Due to factors like weather or changes in season, video detection is not an ideal first line of defense in detecting incoming drones, but it can be a valuable tool for recording drone incidents for future reviews.

Thermal Detection – Thermal imaging is also not a good first line of defense when it comes to detecting drones, but it can be a helpful tool for locating drone operators in a remote area. For example in the smallest of spaces such as the area around a power plant. When a drone is detected in the air, thermal cameras attached to a drone operated by the power plant’s security staff can be used to locate the nearby operator of the intruding drone.

Radar Detection – Drones are often small, low-flying aircraft, making them very difficult to pick up on radar. Radar technology is ideal for finding manned large or long-haul aircraft flying in conventional airspaces. However, their skills are incapable of detecting drones well. When a drone crashed on the White House lawn in 2015, intelligence officials could only see it by sight as it was flying under the existing radar protection.

China Suspends GPS Jamming For Incredible New Years Drone Display

The New Year celebrations in Shanghai this year were particularly spectacular and included a show with 2,000 drones.

Illuminated drones formed a variety of images, including colored shapes, a man running across the sky, and numbers that counted down the seconds to midnight.

Shanghai, in fact much of China’s coastline, has seen repeated GPS jamming and spoofing patterns over the past year.

And previous drone shows in China were spoiled by interference with navigation signals. One incident was reported by Chinese media in May 2018 and another in October of the same year.

Given this history and the success of this year’s show, many have speculated that the Chinese government must have made a conscious decision to avoid interference activities for the duration of the celebration.

Others have suggested that GPS jammer may still be in progress, but the drones are using the Chinese BeiDou satellite navigation system.

It is possible to interfere with GPS without affecting BeiDou. This would be a riskier option, however, as the two systems are operating on nearby frequencies and some “overflow” interference could occur.

China recently announced an increased focus on ensuring that PNT information is available to its population from multiple sources in a “comprehensive” architecture. Such an approach ensures that regardless of the interference from satellite signals, users have the critical location and time information they need.

Given this leadership’s attention, it is likely that the need for unhindered navigation was well considered ahead of the recent Shanghai drone exhibition.

Also, we probably won’t see many future reports of drone shows in China being disrupted by navigation system malfunction.

Fight against employees who use GPS jammers

From the paranoid conspiracy nut to the woman who is afraid of being followed by the employee who doesn’t want to be followed by her boss, the use of devices called GPS jammer is increasing. They are easy to purchase online. You can even find them on sites like eBay. Many people who use them likely assume they are legal and don’t bother to investigate the laws around them. But as an employer, how do you combat and spot employees who use GPS jammers?

What is a GPS jammer?

What Exactly Is A GPS Jammer And How Do They Work? A GPS jammer is a device that uses radio frequencies to transmit a signal that blocks, interferes, or interferes with GPS systems. These devices interfere with all aspects of GPS, including navigation and tracking.

The devices are usually small and most of them are easy to install. A user just needs to plug it into the lighter or car charger port (do cars still have a lighter socket?) And make sure the device is near the GPS tracker so it can interfere with the signal. It takes less than half a minute to turn them on, which makes them attractive to criminals and employees as you can simply plug them in when needed and remove them for the rest of the time.

How do I know an employee is using a GPS jammer?

The good news is, if you have one or more employees trying to use a GPS jammer to disrupt your fleet tracking system, you know. While your drivers may think the illegal jammers are making them invisible, they are instead paying more attention to their behavior.

When an employee uses a GPS jammer to jam the GPS signal, it will show up on the live tracking map or trip history map as a paused or missing trip. If you only connect your jammer during part of the journey, a line will appear between when the jamming started and when the device was turned off. Some later GPS tracking devices even have GPS interference detection. You can also create an exception rule that checks for GPS signal errors and triggers an alert or email when GPS interference occurs.

Once you discover that an employee has disrupted the GPS tracking, you can confront them. They also have a record of the GPS malfunction for disciplinary action like firing the abusive employee for cause.

Final thoughts on GPS jammers and staff

While GPS jammers are illegal, the devices are inexpensive and easy to obtain, especially online. The FCC relies heavily on the public to report the devices, but many people are unaware that it is illegal. Studies of the number of drivers using GPS jammers to hide their whereabouts from employers are inconclusive. However, their use appears to be increasing.

While most GPS jammer users are unlikely to use them to hide illegal activity, the reason behind buying, selling, or using the devices illegally is for public safety reasons. GPS jammers interfere with communication systems, navigation systems, and tracking systems, including emergency services and aviation.

It’s interesting that workers who use them think they can fool their bosses. Instead, employers can easily monitor when and if an employee is using GPS interference and record all incidents. If you are concerned that your drivers are tempted to use the devices, it is important that you monitor your reports and confront the staff who catch you.

You can also let your drivers know that GPS jammers will not help them hide from GPS tracking and that the devices can result in not only termination of their employment but also fines and jail terms for violating federal law. Ultimately, your drivers will find that the devices are simply not worth using.

The cell phone jammer is an instrument that blocks the radio signals of the cell phone from reaching the base station. In fact, the cell phone works by sending and receiving radio signals to and from a network tower. To block radio signals, the cell phone jammer chooses “send signals”, which the cell phone sends to the network tower. In reality, these “transmit signals” are transmitted at a low frequency. Therefore, the cell phone jammer sends its own signals in the same frequency and disrupts the connection between the cell phone and the network station.

Different jammers provide different functions. Some jammers work on all types of networks, while others do not. Therefore, know your demands before purchasing mobile signal jammer.

Today, cell phone jammer users are increasing in great numbers, but, still, a few handles know its correct usage. If you are one of them, here is the list of its uses.

Jammer at university

Along with the advancement in technology, the cheating has also been high tech, the use of mobile phones, wireless headphones and bluetooth devices to get the answer. Many people even hid a transmitter in the examination room.

“The jammer will block the movement of the electronic device, Wi-Fi and Bluetooth operations. Once the body is finalized, the BPSC will be close to the center to clean to install the jammer,” an official said.

The interference operator must be responsible by the supplier concerned in order to avoid local tampering in the inspection center. The jammer effectively turns off the cell phone. They are transmitted at the same radio frequency as the mobile phone, thereby interrupting communication between the phone and the mobile phone’s base station in the tower.

Desktop 5g jammer

Although cell phones were banned in the exam hall, the last year of MBB students at a private university managed to cheat on recent exams using bluetooth devices and microphones. “We have installed mobile phone jammers in four exams to prevent cheating during exams. The education department has also been tasked with closely monitoring the flow of students and carefully examining suspects.” The dean said.

At Kyoto University in Japan.

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 drones have been used. 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

anti uav jammers remote control

Wi-Fi Radio Blocker Let’s learn 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 jammers 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 week frequency 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 can 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 radio signal jammer, you have to use additional tools. Therefore, it transmits the FPV signal using the frequency of 5.8 GHz.

Phantom 2 Vision and Vision+ These two types of drones use 5.8 GHz and 2.4 GHz FPVs separately to take advantage of 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, your drones could be damaged or lost.

Communication function suppression device. Development background and utilization of mobile phone suppression device

While convenience has improved due to the rapid spread of communication devices such as mobile phones and PHS, ringing tones of communication devices and noise caused by telephone calls have become a social problem in spaces such as theaters and halls where a quiet atmosphere is required. I will. In one hall, concerts by prominent conductors have even been interrupted. For this reason, the current situation is that operators such as theaters are strongly demanding the development of effective countermeasure technology.

To prevent ringing tones and calls from mobile phones, PHS, etc.
For this reason, there is a movement to prevent annoyance due to ringing sounds, etc. by using wireless equipment (mobile phone suppression device) that has the function of suppressing ringing sounds and calls from mobile phones.
