First of all, we need to know what is 5g WiFi.The higher the frequency of 5g wifi, the lower the frequency, the better the effect of penetrating the wall; the higher the frequency, the faster the speed.5g WiFi operates at a high frequency of 5000mhz, which supports fewer terminals.2.4G WiFi operates at a frequency of 2400mhz, which is supported by earlier WiFi frequency terminals. Although the mobile phone's WiFi chip supports dual-band operation at 2.4GHz and 5GHz earlier, it still adopts the 802.11n standard instead of the latest 802.11ac standard, which is not really 5g WiFi. it can simply be regarded as 802.11n WiFi running on the 5GHz band, with its performance degraded
For example, 802.11ac's 5g Wi-Fi uses a chip that operates at 5GHz and can cover both the 5GHz and 2.4GHz bands. It improves the problem of small wireless signal coverage in addition to being faster. Although 5GHz has stronger attenuation than 2.4GHz, making it difficult to pass through obstacles, the new standard will make it easier to receive signals in all corners due to the larger coverage area, taking into account the refraction of the signal.
In addition, more people use 2.4G, plus China Mobile WiFi signals, the interference is more serious! 5g is currently smaller, basically no interference!
If you want to block 5g WiFi, you need a 5G signal blocker device with more than 9 antennas and make sure there is a separate 5g module to achieve the effect. For example, an ordinary 8-antenna or 6-antenna will not be able to achieve the shielding effect, because the current 5G mobile phone signal shielding instrument device is a one-piece device with three screens. The more functions you have, the more modules you need. One antenna represents one module
Finally, we need to pay attention to the power of the 5G mobile phone signal shielding device, according to their own needs to buy the right Dazhan electronic signal jammer for sale device, the above is generally used in the examination room and conference room.
