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 this time, all smart phones that are turned on on site are in the network search state, the communication base station signal is lost, and the caller and the caller cannot establish a call.

Everyone understands that within the corresponding working frequency range, smart phones and communication base stations are connected by electromagnetic waves, and information and sound effects are transmitted at the corresponding baud rate and deployment method. Regarding the basic principle of communication, the signal jammer transmits the low-level operating frequency of the channel to the scanner at a corresponding rate in the working link. The scanning rate will cause error interference in the message format signal received by the mobile phone, and the smart phone cannot check the regular information sent by the communication base station, which causes the smart phone to fail to establish a connection with the communication base station.

Product features of mobile phone signal jammer:

1. The oil depot signal jammer reasonably shields the 2G+3G+4G smart phone frequency band + WIFI wireless network jammer;

2. The new aluminum alloy oxidized shell is selected, which has high heat dissipation function, and the long-term reliability of machinery and equipment is good;

3. Select professional chips and technology, slow circuit principle, and high processing speed;

4. UHF broadband interference technology is adopted, which only interferes with the downlink and does not interfere with the communication base station;

5. Adopting multi-channel shielding 3G/4G technology in stages, the actual shielding effect is better;

6. The transmission power of a single unit is 25W, and each safe channel is about 2W-5W;

7. Reasonably shield the range of 0-50 meters (depending on the operator's network signal);

8. It can run continuously for a long time without stopping;

Product advantages of mobile phone signal jammer:

1. The power distribution adopts industrial-grade switching power supply, equipped with high-precision voltage stabilizing circuit, even if the working voltage fluctuates greatly, it will not interfere with the normal operation of the server;

2. The server shell adopts a closed maintenance shell design, which takes into account the unique on-site waterproof, anti-fouling, and anti-damage problems;

3. Equipped with a dedicated air duct ventilated cooling base, and the speed ratio of the radiator fan is adjustable;

4. It can be continuously started and applied to many years of adulthood, with stable functions and long service life. The smart phone signal jammer of the oil depot is harmless to the body. There are product quality inspection and inspection reports; use the inspection and electromagnetic radiation detection services of the Ministry of Public Security; available sites for smart phone signals and mobile phone signal jammers in oil depots:

1. Shield the mobile signals of various examination classrooms;

2. Government agencies, companies and other meeting places that need to keep information confidential, etc.;

3. Courts, detention centers, large and medium-sized prisons, etc.;

4 Places with inflammable and explosive materials such as oil depots and oil and gas fields;

5. Places where the use of smart phones is strictly prohibited;
