Useful 2G 3G 4G Cell phone signal blocker

When you're ready to buy a frequency interrupter device, it's important to ensure that the using frequency of the electronic communication equipment that needs to be interfered, so that you can select a better 4G cell phone jammer.

Due to the rapid changes in mobile technology, mobile communication is becoming more and more popular. In order to buy the best GSM jammer for you at the cheapest price, you need to understand the characteristics and differences of 2G, 3G, and 4G mobile signals:
2G refers to the second-generation mobile network based on GSM and the first technology to use digitally encrypted calls. 2G networks were the first to offer data services and SMS texting. It uses GSM 900MHz and GSM 1800MHz.
3G is the third generation of networks, replacing 2G networks, offering faster data transfer rates and being the first to enable video calling. It is used at 2110 - 2170 MHz.
4G is the fourth-generation mobile communication standard, which provides ultra-broadband Internet access for mobile devices, supports interactive multimedia, voice, and video. It uses 4G LTE (790-821 MHz), 4G Wimax (2500-2690MHz).

4G signal jammer is a device that blocks the transmission or reception of mobile phone signals. It usually uses the same frequency range as the mobile phone to interfere with mobile phone communication or some form of signal cancellation, creating a "quiet zone" where mobile phone users cannot. receive signal. Commonly used in places that require quietness or prohibit the use of mobile phones, such as: high-end restaurants, theaters, churches, libraries, classrooms, test centers, prisons and operating rooms...

GSM jammers are used in some schools and educational institutions in many countries. Used to prevent student distraction and cheating on exams. For example, China has long time to use frequency jammers. Recently, the French Ministry of Education decided to ban cell phones in schools and introduce 4G jamming devices; State prisons in US prepare to upgrade 3G jammers in the prisons.

Will GSM, 3G, and 4G signal jammers still work in the 5G era?

Although the wireless communication technology has gradually upgraded from the original 2G (GSM signal), 3G, and 4G to the now popular 5G signal, GSM, 3G, and 4G are still the most used cellular signals at present. Therefore, the jammer for GSM 3G 4G is still an ideal tool for prohibiting the use of mobile phones, and is used by Europe, America, Europe and other countries because of its lower cost.

Today, some training institutions, schools, use 4G scramblers to prevent cheating, companies use 4G jamer to prevent leaks or improve employee work efficiency, and some factories use it to protect the confidentiality of information, increase production and workshops; and in In the police or army, 4G Phone Blockers are often used to block the communication of criminals or enemies. The police can use GSM signal jammers to prevent criminals from communicating and prevent terrorist attacks, such as jamming bombs controlled by GSM signals...
