At present, there are different models of frequency jammer on the market, and the power consumption of the power supply is mostly between 100-200W. According to this value, it can be calculated that in a building or a floor, if multiple devices are connected in parallel on a power line, the total power consumption of the line can be obtained by multiplying the number of frequency jammer  by t...

The signal jammer is often used in examination rooms, prisons and detention centers to prevent people from using mobile phones in violation of regulations. The Signal Jammer interferes with mobile phone signals by interfering with the downlink signals of the base station. The principle of the mobile phone signal jammer is that the frequency sent by the shield interferes with the normal frequency o...

How to calculate the coverage of 5g cell First of all, you have to have a goal, you have to give a condition to meet the coverage. Data services generally use the rate as the coverage target, such as 1Mbps, and then simulate the user behavior through simulation to get the user's rate distribution and see how far the point that can reach 1Mbps is from the base station. If the conditions change, the...

Defects in previous applications: 1. All use low transmitting power: although it is small in size, the transmitting power is also small and the coverage area is not large, generally no more than 1km; in actual combat, the prevention of UAV should be at least 1km away. If the UAV has entered 1km, its damage or terrorism related behaviors are often completed. 2. All use directional antenna: the prem...

In the current era of proliferation of wireless devices, illegal eavesdropping, drone snooping, cheating in the examination room and other acts have been repeatedly prohibited. The portable jammer has become a "light cavalry" to deal with local electromagnetic security threats because of its small and flexible characteristics. This kind of equipment can quickly cut off transmission links such as r...
