This is not surprising. Zhou Shengjun, a communications expert and founder of Fresh Zao Class, explained to Southern + reporters that 5G is a newly launched network standard in recent years, using some new radio frequency bands, and many older models Does Star 67 Block Cell Phone Numbers do not support shielding. 5G signal. According to the division of 5G frequency bands, 5G of China Telecom and China Unicom mainly use 100MHz spectrum resources in the 3.5GHz frequency band, while China Mobile mainly uses 160MHz spectrum resources in the 2.6GHz frequency band and 100MHz spectrum resources in the 4.9GHz frequency band. The working principle of the mobile phone signal jammer is to use higher power and release stronger signals to suppress the interference normal signals in the corresponding mobile network frequency band, in order to achieve the purpose of shielding. cell phone jammer

The first possibility is that the 5G signal may not be within the working range of the Does Star 67 Block Cell Phone Numbers used on site; the second possibility is that the 5G signal itself has relatively strong anti-interference ability, and the signal jammer failed to successfully suppress the interference. Zhou Shengjun said . The dean of the School of Electronics and Information and the Dean of the School of Microelectronics of South China University of Technology also told the Southern Reporter that at present, the communication technology is constantly upgrading, and the 5G signal system is also different from the original 4G system. The old model of interference equipment cannot completely interfere with the 5G signal. possibly exists. However, he believes that it is not difficult to fill this loophole. Confirm with the telecommunications department in advance what types of signals are near the examination room, and then deploy new models of mobile phone jammers in a targeted manner. "This should be the failure of 5G signals to be shielded by mobile phone jammers, not the 5G signal itself." The dean of the Department of Communication Engineering of the School of Telecommunications of the University of Science and Technology added.
