Buy the right cell phone signal jammer

First, we need to know what 5G WiFi is. High 5G VIFI frequency The lower the frequency, the better the penetration through the wall; the higher the frequency, the faster the speed. 5G WiFi works on a high frequency of 5000MHZ and supports fewer terminals; 2.4G WiFi works on a frequency of 2400MHZ, which is supported by earlier WIFI frequency terminals. Although the WiFi chips of mobile phones support dual-band (2.4GHz and 5GHz) operation earlier, the protocol used is still the 802.11n standard, and the latest 802.11ac standard is not adopted. It is not 5G WiFi in the true sense. It can be simply Think of it as 802.11n WiFi running on the 5GHz band, with a compromise in performance.

5G Wi-Fi like 802.11ac uses a chip operating at 5GHz, which can cover both 5GHz and 2.4GHz frequency bands. In addition to being faster, it can also improve the problem of small wireless signal coverage. Although 5GHz has stronger attenuation than 2.4GHz, it is difficult to pass through obstacles. However, due to the larger coverage, considering that the signal will be refracted, the new standard will It’s easier to get a signal from all corners.

In addition, there are more people using 2.4G, coupled with CMCC’s WIFI signal, the interference is more serious! 5G is relatively rare at present, and there is basically no interference. If you want to shield 5G WiFi, you need a mobile cell phone jammer with more than 9 antennas, and ensure that there is an independent 5G module to achieve the effect. Like ordinary 8 antennas or 6 antennas, the shielding effect cannot be achieved, because the current mobile phone signal jammers All are integrated, with three Netcom screens. The more functions, the more modules are needed. One antenna represents one module. Finally, it is also necessary to pay attention to the power of mobile phone jammers, and buy a suitable mobile phone jammer according to your own needs.
