Cell Phone Receiver Block Diagram

With the advent of the summer vacation, primary and secondary schools all over the world began to have holidays, and the tests for parents came one after another. What should children do if they are addicted to chatting on mobile phones, what should children do if they don’t have a good rest and play mobile games in the middle of the night? How to do? These are the questions I've been getting the most recently. When encountering such inquiries, I generally recommend parents to communicate with their children so that they can learn self-discipline. However, some parents have also reported the actual difficulties and hope to purchase a household Cell Phone Receiver Block Diagram to interfere/interrupt the mobile phone signal. Yesterday, a brother hoped that his sister could concentrate on her studies, and he sacrificed the fun of playing with his mobile phone to buy a mobile phone signal jammer, and his heart was still very warm! We know that the current mobile phone signal jammers are all frequency bands. It can block all 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under the three operators of China Mobile, China Unicom and China Telecom. Its principle is to use its own The frequency emitted by the mobile phone interferes with the frequency emitted by the mobile phone receiving base station and wireless router, so as to achieve the purpose of shielding them. Therefore, if there are users who can't make calls or mobile Internet cards, wait patiently, and they will return to normal after the test.

Now many schools are asking how much is the test room-type 5g mobile phone signal jammer?

This type of low-power Cell Phone Receiver Block Diagram is mainly used for indoor and escort vehicles. The test site is used less frequently. If you need to use low-power cell phone jammer , you need to install several more. The second is 1000 yuan - 5000 yuan, which needs to be installed according to the site environment where you are.
