The complexity of jammers that interleaved networks blocking signals
Unless you can physically locate the jammer itself (which usually looks like a walkie-talkie, cell phone, or wireless router) and then turn it off, blocking the signal jammer is not your best option. feasible. If you are tech-savvy and can change the operating frequency of your phone, you can also be lucky enough to bypass the jammer. But it depends on the complexity of the jammer blocking the signal. If you think you may be a victim of a mobile phone interference attack, then the best option is to move away. The broadcast range of a mobile phone cell phone jammer is usually no more than 30 square feet, so leaving your current location is usually enough to escape the jammer's range. Similarly, if you are the victim of someone who uses a cell phone signal blocker, please contact law enforcement or file a complaint with the FCC.
In the United States alone, a one-day GNSS failure is expected to cause US$1 billion in losses (1). GNSS is a reliable system. To keep it in this state, professional GNSS receivers must be alert to all vulnerabilities that may be exploited. The use of GNSS receivers has strong anti-jamming capabilities and identity theft capabilities, and is the key to ensuring PNT (positioning, navigation and time) security. These portable jammers are continuously controlled by a central administrator who can allow or prohibit cellular communications. These cellular jammers are connected via CAN (controller area network) in the local area network and managed by the central base station (CBS). The smart scrambling system controls everything from the detection of the alarm, from when and where the mobile phone tries to make a call to blocking the call.
If you encounter this situation, you need to use a phone blocker. Since hacker attacks, smartphones have been used everywhere. Many people struggle to discuss their personal, business or daily affairs in public places, forcing everyone to listen in their surroundings. For example, you can see mobile chat users everywhere in trains, subways, buses, grocery stores, shopping centers, and coffee shops. All these factors cause some people to keep their secrets in their hands-cell phone jammers can be put in their pockets, cell phones can easily avoid radio leakage, but you can also enjoy a quiet environment.
