Customers report that the shielding distance of some brands and models of 5G shields is shorter. Why?

When some customers ask us about mobile phone shielding equipment, they will mention a situation, that is, they have tried or purchased 5G jammers of other brands, but in the actual use process, they found that these so-called 5G signal jammer, their shielding distance It is obviously shorter, and sometimes there is no shielding effect at all for some 5G frequency bands. Why is this?

5G jammer means that in addition to maintaining the original shielding effect for the original 2G, 3G, 4G standard or frequency band of the mobile phone, it also specifically targets the 5G standard and frequency band for effective signal shielding. The original 2G, 3G, and 4G frequency bands of mobile phones include: 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, 2500MHz, 2G, The frequency bands of 3G and 4G mobile phones are all concentrated in the interval of these 8 frequency bands. From the perspective of the 5G communication frequency band that will be fully popularized in 2020, China Radio and Television Mobile has been added, and there are a total of four communication operators.

At present, the distribution of the four operators in the 5G commercial frequency band is: 700MHz, 2600MHz, 3400MHz, 3500MHz, 4800MHz, of which 4800MHz is not fully applied and is mainly used in the construction of 5G private networks in individual places.

10 Antenna Cell Phone Signal Jammer

On the whole, a fully qualified 5G jammer now needs to cover the following frequency bands: 700MHz, 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, 2500MHz, 2600MHz, 3400MHz, 3500MHz. There are a total of 12 frequency bands.

Then, the question raised by the customer is that some brands of 5G jammers have the greatest possibility that the actual use effect is not good, that is, the above-mentioned 12 frequency bands are not fully covered. It is possible that the 12 frequency bands were intentionally or unintentionally reduced or merged for reasons of cost control and lowering the selling price of 5G shielding products, resulting in poor shielding effect for 5G signals.

At present, most manufacturers of 5G jammers have modularized production and assembly of each frequency band in the product. Therefore, if you want to check whether the 5G jammer you choose to buy meets the basic functional design requirements, first count the How many built-in modules does the 5G shield have, or just count the number of antennas corresponding to them.
