Smartphone radio jamming is specially designed for people who want to protect their privacy by preventing eavesdropping and eavesdropping with our current flood of satellite positioning (car positioning, cell phone positioning, googlenet positioning, etc.). Due to the characteristics of all current GPS satellite positioning systems, the effective radio wave blocking range is to block, interfere, adjust and suppress GPS satellite signals from 2 to 15m to form an effective protection zone,…

1. The effective shielding range of the test panel signal monitor varies in different occasions. This is closely related to the signal field strength of the site. Different types of mobile phones may not have the same shielding range on the same site, so they should be selected according to the actual situation.

2. The reasons that affect the shielding range of the cell phone jammer include: distance, direction, barrier-free objects of the base station, wall materials of the site…

If the mobile phone signal jammer is installed outdoors, it is necessary to take waterproof and lightning protection measures. It is usually recommended to equip the mobile phone signal jammer with a special installation box. , used for heat dissipation, the top of the box is opened to extend the antenna of the mobile phone shield, the holes are sealed with hot melt adhesive, and the bottom of the box is provided with a power input hole and a diversion hole to avoid water…

First, the bigger the power, the better

1. The frequency output of the host is inaccurate, the frequency drifts, and the bandwidth is too wide, which wastes power and causes interference to the base station.

2. The shielding efficiency of the simple frequency sweeping power suppression method is not high, and the radiation generated is relatively large.

3. The power is falsely marked and the publicity effect is exaggerated, so that the nominal power has no actual…

There are more than 20,000 drones in China, but only 10,000 people in the country have obtained a drone driver's license, which means that nearly 50% of the drones are in a "black flying" state. "Shu Zhenjie, director of the UAV System Research Office of the China Institute of Aviation Comprehensive Technology, gave this set of data. The safety problems caused by UAVs are of concern. How to tame "black flying" UAVs? What kind of order control is established? China What technological means…

In some characteristic places, it needs to be applied to the signal jammer, mainly to shield the signal. Since the signal will appear at any time, the signal jammer should also be turned on at any time, but doing so is likely to cause the current to be unstable. The solution is to change the current size. So how to change the current size of the signal jammer? There are three main methods:

1. Replace the resistor or power supply (voltage). In the circuit of the signal isolator, the…

Unmanned aerial vehicles are controlled remotely and wirelessly via radio waves. It is an invisible electromagnetic spectrum (frequency in MHz). There should be a transmitter to send the message and a receiver to get the message that the radio waves work. A lot is that the transmitter and receiver must operate at the same frequency.

WiFi is often used for remote control drone work, such as Aum AR drone 2.0, and the…

Signal jammers produced today are divided into stationary and portable. The first one works using the network or other power source (the same cigarette lighter in the car). They work mostly indoors to ensure the secrecy of negotiations, to keep theatres and museums quiet, and to eliminate the possibility of cheating during exams. The second size is much smaller and they usually work on batteries or batteries. They have a smaller range. They are also used to counter the recording of…

Can mobile jammers block all signals? topsignaljammer tell you! Now, the emergence of monitoring has removed many hidden dangers that disrupted the order in the examination room, allowing candidates to take the examination in a fair environment. However, it is inevitable that there will be some "fish that slip through the net". At this time, it is necessary to use mobile communication jammers to completely create a fair test environment! The principle of the mobile communication jammer is…

GPS is also known as the Global Positioning System. We are very familiar with GPS signals in our lives. Our cars, cell phones, and even some smartwatches all have GPS location and navigation systems. GPS plays an important role, especially in some military areas.

The development of science and technology plays an important role in the further expansion of GPS technology and is also very important for military applications. In modern electronic warfare, GPS signals are closely related…

With technological advances around the world, the financial industry is keeping up. Millions of people are embracing this fundamental change in mobile banking. People are banking on a variety of mobile devices using his device, and it is expected that millions will join this trend in the coming years and months. Security is paramount for almost all applications, but for banking applications, security requirements are more urgent. This is and should be a top priority when building…

The 2018 World Cup will take place in Russia. It is an exciting time indeed for football fans. Of course, they'll spend time watching the game. If you get interrupted by the phone, can't watch TV before the game, or your friends are really sad and disappointed, now there is an urgent need to avoid cell phone noise. In this case, the use of the signal can interrupt the interference of the cellular phone signal. This device may be your best choice right now.

When there is an important…

When ordinary civilian cell phone jammer are used in places with strict cell phone protection requirements, such as prisons, they exhibit the following manifestations:

1. The armor effect of the armor area is weak and there are more blind areas and blind spots. Some areas near the cell area window, especially on the base station side, can also be connected to cell phones under certain antennas…

The operation method of the cell phone jammer is to first select the area where the mobile phone signal needs to be disconnected, and place the disconnector on the desktop or wall of the area. After assembling, connect the isolating switch, turn on the power, and turn on the power switch.

After the signal jammer device is connected, tap the power switch to disconnect the device to operate. At…
