Wireless jammer shields mobile signals
Cell phones are electronic devices that need to communicate with other devices through cell towers, and wireless communication requires electromagnetic waves. According to the characteristics of electromagnetic waves, equipment needs to receive within the corresponding frequency range, so signal shielding affects electronic products. The frequency of the device causes the two sides to have different frequencies, thereby achieving a shielding effect. For Bluetooth and wifi, the wireless signal jammer can block these networks. Bluetooth and Wi-Fi frequency bands are added to the scanning range, which can block connections within the scanning range.
Mobile networks and WIFI have become indispensable things in life. It can be said that without mobile networks and WIFI, mobile phones would not have the ability to connect to the outside world. Because the frequency band of mobile network and WIFI signals is generally between 450MHz and 6GHz, the signal jammer can effectively block communication signals in this frequency band. When working, it will emit interference signals that interfere with the base station channel frequency band, and the information cannot be decoded normally, causing the mobile phone to be unable to establish a normal connection with the base station. When the mobile phone cannot determine the service area after multiple attempts, the mobile phone will display no signal, search the network, and is not in the service area.
Different from the traditional co-frequency suppression method, digital technology integrates signal shielding, monitoring and management. This product realizes the supervision function of illegal use of mobile phones in the coverage area by blocking the downlink signals of mobile phones. It can support the shielding of mobile phones of different standards and will not interfere with the uplink of the base station. Wireless signal jammers are effective and low-cost. In the shielded area of the examination room, they can effectively block mobile phone communication services of various operators, including voice, data, SMS and other services. Network standards include 2G, 3G, 4G and 5G. Due to the use of digital technology, the equipment does not produce noise and will not affect meetings, exams, etc. during use.
In recent years, various types of wireless signal jammers have emerged in endlessly, making us dizzy and beautiful. However, in fact, not all products are suitable for us to use ourselves. Some products are for public use. Therefore, it is not suitable for us to apply it in other fields. There is a very special jammer that is also presented in front of us. Its name is mobile phone wireless signal jammer. So what are the advantages of this type of product? When we use a wireless signal jammer, you will find that no matter where we are, as long as we can turn on the jammer, no one can find our wireless signal. In other words , the effect of household products is more obvious than that of ordinary public products. In such an environment, we can always easily block all signals, but if we are using a public jammer, then there may be a shielding effect. Instability problem, so we need to understand the detailed application effect.
What are the advantages of wireless signal jammers? The following editor will explain the four major advantages of mobile phone signal jammers one by one: 1. Wide application areas. Mobile phone signal jammers are mainly used in examination rooms, but are not limited to examination rooms. They can also be used in prisons, gas stations, to prevent mobile phone bombs, oil depots, etc. Liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, libraries, school dormitories, special security and confidential places (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitary escorts on-site) etc. will be used. 2. Highly targeted mobile phone wireless signal jammers can be mainly used for domestic college entrance examinations, domestic postgraduate entrance examinations, adult college entrance examinations, self-study examinations and various college and university examinations, as well as various middle schools, technical secondary schools, vocational high schools, prisons, detention centers, conference rooms and other application mobile phones. Cheating, random text messaging, communicating with people outside prison, and collusion in confessions, etc. 3. The shielded signals are diverse and effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE. 4. Model advantages 1. Adopt high-dispersion aluminum alloy shell, low operating temperature, and more stable shielding effect. 2. Built-in silent turbo fan, low working noise. 3. Separate power adapter. 12V/24V DC power supply, convenient for vehicle-mounted mobile work. 4. External antenna design, unified interface at one end makes the appearance more beautiful and decent. It has an anti-loosening design, and the antenna and host have marked working frequency bands to facilitate one-to-one correspondence.
