The Signal Jammer has been following the development of the times and is more than sufficient for the current 5g signal. Generally, this kind of shielding equipment adds 3.6g antenna and 5.8G antenna, which can fully shield DCS, CDMA, WCDMA, WiFi, FDD, GSM, TD-SCDMA, TD-LTE, 3.6g, 5.8G and other frequency band signals.

Some schools may choose to install signal shielding equipment in order to prevent students from not listening carefully, carrying mobile phones and ensuring classroom discipline. The professional signal shielding equipment can shield all the signals of mobile, China Unicom and telecom operators, WiFi signals and Bluetooth signals. In addition, the Signal Jammer interferes with the frequencies sent by the mobile phone receiving base station and the wireless router through its own frequencies, so as to achieve full band shielding.

At present, 5g has been popularized, and the Signal Jammer has also added 5g interference module with the times. The current shielding equipment can shield 5g signals. Why can some shielding devices fail to shield 5g signals? In fact, this is mainly due to the different signal strengths of the places of use. If there are different places and different environments, or if there are base stations nearby, the signal strength in the school will be very large, so the shielding effect will be offset. Some shielding devices have a long history and are not equipped with 5g modules. Naturally, they do not support interference to 5g signals. At this time, you can contact the manufacturer for upgrading.
