It has been several years since we entered the 5G era. 5G jammers are also closely following the development of 5G communication. However, wherever there is a need to restrict the use of mobile phones, we will follow up in time and upgrade the original old-type mobile phone signal shielding equipment. . However, during this process, we will receive feedback from a small number of customers, saying that the effect of signal shielding has been reduced, especially for the signal of 5G mobile phones, and the effective shielding distance has been significantly shortened, so the problem arises. What should I do if the 5G jammer's shielding effect on 5G signals is not good?
Since the development of mobile phones from 4G to 5G, due to the need for higher data transmission rates, various communication operators have launched new 0.7 GHz (China Radio and Television), 2.6 GHz (China Mobile), 3.6 GHz (China Unicom) according to the country's division of mobile phone frequency bands. , China Telecom) and 4.9GHz (China Mobile + China Radio and Television) and other high-frequency frequency bands, these newly launched 5G mobile phone frequency bands, in addition to higher frequencies, have a more obvious feature that their frequency bandwidth is relatively large, each operator The commercial capital has almost obtained a frequency bandwidth of at least 100MHz, which will lead to a consequence: if 5G jammers need to achieve effective shielding against 5G signals, they must ensure that sufficient power is applied to each 5G frequency band.
Before the advent of 5G, mobile phone jammers in the past usually only need to install 6-8 signal shielding modules, and the frequency bandwidth of each shielding module will not reach 100MHz, generally around 20~60MHz, but in 5G mobile phone jamming When the device starts to be mass-produced, each signal shielding module must cover a frequency bandwidth of at least 100MHz, and these are all newly added frequency bands, so that the production of a standard 5G jammer requires at least 10~12 signal shielding modules. module.
As a manufacturer, in order to meet the functional requirements of competitors and at the same time ensure the cost control and price competitiveness of 5G jammers, they will not rashly adopt the method of adding 5G signal shielding modules to improve the effect of signal shielding. This is why some customers reported that the shielding effect of 5G signals is not ideal.
What is the solution to this problem? In fact, it is relatively simple, that is, to get rid of the constraint of controlling production costs, to divide the shielding module in the 5G jammer, especially for the 5G signal shielding frequency band, more reasonably, to split the broadband into narrowband, and to increase the shielding module. quantity.
