Block A Restricted Call On Cell Phone Is The Trend Of Scientific Research

Today's common test room Block A Restricted Call On Cell Phone can usually block the signals of all operators currently on the market. Also included in it is the more obscure VIFI, which has avoided all opportunities for students to opportunistically. In addition, according to the frequency range of the signal, the signal shielded by the examination room signal is also different. Nowadays, high-tech is more developed, and the shielding of 4G signals can usually be shielded by any signal shielding device in the examination room. However, smart technology is too efficient. Now gradually open the 5G period. This kind of signal jammer in the examination room also needs to be updated. However, the technical level of many enterprises has not been able to keep up. In the field, there are very few companies that use shielding 5G signals at this stage, and there are several test room signal shielding devices that shield 5G signals. With the development trend of scientific research, it has already become inevitable that the process of signal jammers in the examination room will be eliminated without upgrading. Examination room signal blockers like this are generally used to block signals on mobile phones. The use of smartphones around the test room can also be affected by the signal. However, today's test room signal blockers have rising signal blockers, which have already had less impact on general mobile phone signals. Usually, they are mainly used to influence cell phones that send special signals. At present, the market prospect of the progress of the sales market is very good, and the signal shielding of such an examination room is getting better and better, so there is no need to worry about the campus that must be ordered.

During the college entrance examination, the school will open Block A Restricted Call On Cell Phone , which will affect the call quality of customers around the test room, such as frequent call failures, missed calls, dropped calls, intermittent calls, and slow Internet access. After the test, it will return to normal. At the same time, in order to ensure smooth signals around the campus, the operator has arranged in advance communication engineers to test the entrances and exits of each test center and the rest area for parents accompanying the test, and expand the software and hardware capacity of nearby base stations to ensure that high traffic, High Flow. We have done our best to keep your communication flowing, except for the signal being blocked during the exam. We know that every year in the college entrance examination, in order to prevent fraud in the examination, all communication signals in the examination room will be blocked. There are cell phone jammer in the test room. At the same time, there is a radio monitor outside the test room that can help to get the electromagnetic wave signals in those frequency bands that the mobile phone jammer can't care about, and monitor the radio wave signals of unknown sources in real time. The working principle of the mobile phone signal jammer used in the college entrance examination is to bury useful electromagnetic wave signals in a large number of useless signals.
