BARRIER-Ⅱ wireless frequency jammer is the latest special frequency jamming equipment introduced by our company on the basis of BARRIER-Ⅰ according to the needs of domestic public to arrange explosive work and security and confidentiality work. It can be applied to important departments such as the local public security system, the National Security Bureau system, and party and government agencies. This device transmits specific radio signals to block the interfered target from receiving remote control commands or communication signals to achieve the purpose of interference.
The BARRIER-Ⅱ wireless signal jammer uses the most advanced frequency generation and modulation techniques today. It can transmit interference signals in the frequency bands of 10MHz---2500MHz and public network mobile communications, and can simultaneously interfere with AM, FM, VHF, UHF, CDMA, GSM, DCS, FDMA, PHS and other radio signals of various frequencies and communication standards. Including commonly used children’s toy remote controls; model airplane remote controls; small radio walkie-talkies; car lock remote controls; self-made radio devices; mobile communication terminals and other dozens of radio equipment. In particular, the latest international technology is adopted to expand the interference frequency band to 2.5G, which can effectively interfere with the use of high-frequency high-end products such as digital transmission and eavesdropping. It is widely used in public security search and explosion detection and EOD sites; politicians’ defense; meetings and important Anti-eavesdropping and confidentiality work in places are important equipment of the security and counter-terrorism department.
