Portable jammer, many people have heard the name. But how and how does the device work? Perhaps few people know. This is why today we specially invite experts to answer us. To interfere, the portable jammer sends RF power (CW + modulation) at the same frequency used by the enemy link or network. The enemy receiver (“listening” side) receives signals from the cell phone jammer and its “partner”. The strongest will win; if the capacity of the jammer is greater than the capacity of the “partner”, the “listener” will not be able to “understand” the message/data correctly. Or, if the capacity of the “partner” is greater than the capacity of the jammer, the “listener” will probably be able to “understand” the message/data correctly, and the communication link between the “partners” will remain uninterrupted. This explanation is a bit superficial and aims to simplify things. However, if we try to study the problem more deeply, we can compare the signal levels of the two “links” to get more parameters. An example is the SNR (signal-to-noise ratio) that the receiver “sees” at its input.
Researchers can easily find security vulnerabilities and notify vendors. However, on the other hand, it is difficult to find a solution that gives effective results. I worked with Martha and found some simple and useful techniques that can be applied if there is a network-connected device at home. These are just general suggestions, because it is difficult to find a solution that works for all devices, and the solution is very complicated, because each product is different: because the attacker will change the default password on the device and try to take advantage of it. Many families use signal jammers to protect information.
A mobile phone jammer mobile phone is a device that enables the 13759 mobile phone to send signals and generate transmissions in the same frequency range, effectively preventing strong interference. People who use the phone to make a complaint lose their signal, but don’t know why. The phone shows poor reception. With the widespread use of mobile phones, there has been a resurgence. Although some people practice good etiquette on the phone, there are still many people discussing their private, commercial or social affairs in public places and forcing everyone to listen. People often chat in trains, subways, buses, grocery stores, shopping centers and cafes to make their compatriots even more angry. This allows some people to hold it in their hands. If you use Messenger in your wallet or wallet, you can turn off your phone by flipping the switch. As long as the device is powered on, if the distance between the device and the signal source is insufficient, it cannot be reconnected.
