Is the old mobile jammer unable to shield the 5G signal?

Is the old mobile jammer unable to shield the 5G signal?

  • 2023-01-07
"It's not surprising." Communication experts explained that 5G is a new network system introduced in recent years, which uses some new radio bands. Many old mobile jammers do not support shielding 5G signals.

According to the division of 5G frequency band, the 5G of China Telecom and China Unicom mainly uses 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 jammer is to use the higher power and release stronger signals of the mobile jammer to suppress the normal interfering signals in the frequency band of the corresponding mobile network, so as to achieve the purpose of shielding.

"The first possibility is that the 5G signal may not be within the working range of the mobile jammer used on site; the second possibility is that the 5G signal itself has strong anti-interference ability, and the mobile jammer failed to suppress interference." The expert said.

At present, with the continuous upgrading of communication technology, the 5G signal system is different from the original 4G system. It is possible that the old mobile jammer cannot completely interfere with the 5G signal.

It is not difficult to fill this loophole. Confirm in advance what types of signals are near the examination room, and then deploy a new mobile jammer. The original technology is upgraded to 5G, which can shield 2G/3G/4G/5G/WiFi/Bluetooth/y invisible headset/walkie talkie/wireless data transmission and other signals, and completely achieve full system shielding without leaving loopholes.
