How to upgrade the police jammer to 5G signal shielding? from dojammer's blog

The police frequency jammer purchased by the customer earlier did not originally have the operator's 5G frequency interference module. With the gradual popularization of 5G signals, the police jammers that did not have 5G frequencies cannot shield and interfere with 5G signals, so the jammers must be upgraded to 5G signal frequencies to shield and interfere with 5G frequency signals.

According to the division of operator 5G signal frequencies issued by the Ministry of Industry and Information Technology, the 700M shared by China Broadcasting and Television and China Mobile, the 3.4G-3.6G frequencies of China Telecom and China Unicom are added to the original 4G signal frequencies of operators, and the original 2555-2655 of China Mobile is expanded to 2515-2675M. That is to say, the police frequency jammer needs to upgrade the 5G shielding module, and 2-3 modules need to be added, and the mobile 2.6G module needs to be expanded. Shielding interference of 5G signals can be achieved. Some friends may ask, why is there no increase in the 4800-4900M frequency of China Mobile 5G? This is because the 4.8G-4.9G frequency band has not been fully rolled out at present, and it is necessary to determine whether the police jammer needs to add an interference module for this frequency band according to different usage sites.

To upgrade the 5G shielding of the police frequency jammer, it only needs to add 2-3 interference modules for the frequency band and expand the frequency of the 2.6G module, which can meet the mobile phone signal shielding of most usage sites.
