Install wireless signal jammers in secret locations to prevent information leakage
In order to prevent internal information from being stolen from the outside world and leading to leakage incidents, many technical preventive measures have been taken in secret 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 secret places?
Information sharing and communications inevitably take place in secret locations, and some of the data exchanged and communicated may still be leaked, intentionally or unintentionally, to the outside world via the unit's internal wireless network or field personnel's cell phones. It is the most common channel leading to information leakage and some are malicious and targeted, installing information stealing devices in secret locations in advance and then leaking them outside in some way, e.g. B. wireless information about a specific frequency band transceiver. Faced with these leaky methods and means, it is only necessary to select the appropriate frequency band radio signal jammer and keep it open in the secret location to ensure that the information and data in the ciphertext cannot be effectively transmitted to the outside world, thereby causing the Place for sending and internal and external channels for receiving information is cut off.
For wireless signal jammers installed in secret places, wireless data transmission frequency bands should at least include: all 2G, 3G, 4G, 5G cellular frequency bands, WiFi2.4G/5.8G, Bluetooth, 433MHz wireless data transmission, 1200MHz wireless image transmission Waiting. In addition, the radio jammer should also have some advanced redundancy function. If other suspicious frequency points or designated special frequency bands are found in secret locations, signal shielding modules for those frequency bands should be quickly added to the wireless signal jammer.
