In various examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military centers, libraries, theaters and other places, in some cases, the use of communication equipment such as mobile phones is prohibited. In order to prevent the use of mobile phones in these places, wireless wifi signal jammer is used to block mobile phone signals. However, at certain times, such as when the examination room is conducting an examination, in addition to shielding mobile phone signals, other communication devices including walkie-talkies, Bluetooth headsets, etc. need to be shielded. Can the multifunctional wireless signal blocker block the walkie-talkie?
In fact, the wireless wifi signal jammer is aimed at the uplink and downlink channels of the mobile phone system, using frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency; customize a spherical shielding space according to the power of the jammer, within the specified range The shielding magnetic field is automatically formed, which can make the function of sending and receiving signals of mobile phones within the specified range invalid, and cannot dial out and dial in, and cannot access the Internet, so as to achieve the purpose of forcibly disabling mobile phones. As long as the frequency band used by the walkie-talkie is shielded, the use of the walkie-talkie can be effectively shielded.
