High-Quality Wifi Jammer - Guardian of Protection

High-quality wifi jammer has recently become popular due to their extraordinary advantages. These high-quality Wifi jammer devices help you maintain privacy and protect you from unwanted attention by jamming various spy devices. High-quality Wifi jammers help you keep your important data and information safe by acting as a barrier against information theft. No matter who you are and where you are, a high-quality wifi signal jammer can protect your privacy well.

What is a high-quality Wifi jammer?

It is a high-quality wifi frequency jammer for blocking such high-frequency signals. A major disadvantage of WI-FI signals is that they block both Bluetooth and wireless signals due to their matching frequencies. There are several types of high-quality wifi jammer kits available that can be used to secure Wi-Fi signals on different frequencies. Portable high-quality Wifi jammers are still famous even in this type due to their size.

Wi-fi frequencies are primarily used to transmit data to base stations. High-quality blutooth wifi jammer exist when this data is stored by nasty people and abused. Obviously, everyone is also extremely careful about their privacy and private data. Especially for celebrities who don"t want others to see or hear them. To help you protect your privacy, high-quality wireless wifi jammers are the best option because they block all devices, such as wireless wifi devices, with a signal blocker. With your high-quality Wifi jammer, all these spying devices will be completely jammed. Therefore, a high-quality wifi blocker is a good tool to protect your privacy, especially if you are a famous person or someone who is very privacy-conscious, it can effectively solve the trouble you are facing.

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.

WLAN wifi jammer full 360° blocking signal

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.
