Installation of wireless signal jammers as technical precautions in classified places

In order to prevent the internal information from being stolen by the outside world, which leads to the occurrence of secret leakage incidents, many technical preventive measures are adopted in secret-related places, and the installation of wireless signal jammers is one of these technical preventive measures. So how does the wireless signal jammer ensure the security of information protection in classified places? Here we discuss this issue.

Information exchange and communication may inevitably exist in secret-related places, and some of these exchanged and communicated data may still be leaked to the outside world intentionally or unintentionally through the internal wireless network of the unit or the mobile phones of on-site personnel. It is the most common channel that leads to information leakage, and some are malicious and targeted, by installing information stealing equipment in the secret place in advance, and then passing it to the outside in some way, such as through a certain frequency segment wireless information transceiver. In view of these leaking methods and methods, it is only necessary to select the wireless signal jammer of the corresponding frequency band and keep it in the open state in the secret-related place, which can ensure that the information and data in the secret-related place cannot be effectively transmitted to the outside world, thus cutting off the place. Internal and external channels for sending and receiving information.

For the wireless signal jammer installed in the secret place, the frequency band for wireless data transmission should at least include: all 2G, 3G, 4G, 5G mobile phone frequency bands, WiFi2.4G/5.8G, Bluetooth, 433MHz Wireless data transmission, 1200MHz wireless image transmission, etc. In addition, the wireless signal jammer should also have a certain extended redundancy function. When other suspicious frequency points or designated special frequency bands are found in the secret place, the signal shielding module for these frequency bands should be quickly added to the wireless into the signal jammer.
