Install wifi jammer in confidential places as a preventive measure. In order to prevent internal information from being stolen by the outside world and leading to leakage incidents, many technical preventive measures have been taken in confidential places, and the installation of wifi signal jammer is one of these technical preventive measures. Then How does the wifi jammer device ensure the security of information protection in secret places? We discuss this issue here.
Information exchange and communication inevitably exist in classified places, and some data exchanged and communicated may still be leaked to the outside world intentionally or unintentionally through the internal wireless network of the unit or the mobile phones of field personnel. It is the most common channel leading to information leakage, and some are malicious and targeted, by pre-installing information stealing equipment in secret places, and then passing it to the outside in some way, such as through a certain frequency band wireless information transceiver. For these leaking methods and methods, it is only necessary to select the wireless wifi signal jammer of the corresponding frequency band and keep it turned on in the secret-related place to ensure the leakage of secret-related information and data. The relevant venue cannot be effectively transmitted to the outside world, thus cutting off the venue. Internal and external channels for sending and receiving information.
For wifi signal blockers installed in secret places, the frequency bands for wireless data transmission should at least include all 2G, 3G, 4G, 5G mobile phone frequency bands, WiFi2.4G/5.8G, Bluetooth, 433MHz wireless data transmission, 1200MHz wireless image transmission Wait. In addition, the wifi blocker device should also have a certain extended redundancy function. When other suspicious frequency points or designated special frequency bands are found in secret places, signal shielding modules for these frequency bands should be quickly added to the wireless wifi jammer.

In the information age, electronic devices such as mobile phones have become an indispensable part of people's daily life. They are used in various fields, which not only facilitates people's lives but also causes troubles.Many suffer the inconvenience. This is the entry point, but I didn't notice the annoying noise on the phone! We promise a quiet environment. Of course, you won't have internet access, so you can focus on your active activities. Wifi jammer that support radio waves and cell phones are mainly used in security facilities, hospitals, schools, and private schools where the use of cell phones is prohibited, and in places where the use of cell phones is not permitted, such as banks, lobbies, conference rooms, libraries, shops, and schools. common. If stray radio waves can be emitted at the frequencies used by the telephone, the communication of the telephone will be interrupted, thus reliably preventing all telephones in the hall from ringing (except communication). Unnecessary cell phone alerts cannot be avoided. For the same reason, a similar effect can occur in hospitals where quiet rest is required. In addition, confidential information is kept secret in a data center or the like. All phones in the lobby will ring (albeit for communication). Unnecessary cell phone alerts cannot be avoided.

We all know that wireless wifi jammer is widely used in our daily life. It has the characteristics of flexibility, convenient operation, fast voice transmission, and economical use. It is the basic means to realize production scheduling automation and management modernization. What is the principle of a wireless wifi signal jammer?
1. Launch part:
A phase-locked loop and voltage-controlled oscillator (VCO) generate the transmitted RF carrier signal, which is buffered and amplified, excited, amplified, and power-amplified to produce the rated RF power.
2. Receive part:
The receiving part adopts the double-conversion super-heterodyne method. The signal input from the antenna is amplified by the radio frequency after passing through the transceiver conversion circuit and the band-pass filter. The first local oscillator signal of the phase-locked loop frequency synthesizer circuit is mixed at a first mixer and generates a first intermediate frequency signal. The first intermediate frequency signal is further removed from the clutter signal of the adjacent channel by a crystal filter. The filtered first intermediate frequency signal enters the intermediate frequency processing chip and is mixed with the second local oscillator signal again to generate a second intermediate frequency signal. Generate an audio signal. The audio signal enters the volume control circuit and power amplifier and is amplified, band-pass filtered, and wireless wifi blocker.
3. Modulation signal and modulation circuit:
The human voice is converted into an audio electrical signal through a microphone, and the audio signal is directly modulated by a voltage-controlled oscillator through an amplifier circuit, a pre-emphasis circuit, and a band-pass filter.
4. Signal processing:
After the CTCSS/DTCSS signal generated by the CPU is amplified and adjusted, it enters the VCO for modulation. After receiving the low-frequency signal obtained after frequency division, a part of it is filtered and shaped by amplifying and sub-audio band-pass filter, and then enters the CPU, which is compared with the preset value, and the result is used to control the output of the audio power amplifier and the speaker. That is if it is the same as the preset value, turn the speaker on, otherwise, turn off the speaker.
