There are many reasons why you can use a cell phone jammer. Some of them can be used legally with the permission of the local government. Cellular jammers are often used when the mobile signals are blocked and cannot ring for security reasons or due to a forced mobile mute. A cell phone jammer is an instrument that prevents a cell phone from receiving signals from a base station. When in use, the jammer effectively deactivates the phone. These devices can be used almost anywhere, but mainly because they have to be muted, calls to these locations are particularly vulnerable to interference.
In order to be fair and prevent cheating on exams, this problem is always something people are looking for to solve, and we will do our best to help you. First of all, you should know that these devices cannot be used without a smartphone, and of course they are widely used, but not everyone can afford them. Before trying an in-depth approach, try talking to people, explaining that using these Bluetooth headsets makes their smartphones vulnerable to attackers because the 2.4 GHz frequency is quite vulnerable.
If that doesn't work, this portable wifi jammer will do exactly what you need. First of all, it is portable, so you can take it with you. Another advantage here is the interference range of -15 meters or 50 feet. The only problem here is that Wi-Fi and Bluetooth use the same frequency, so it will also drop when the interfering device is on all Wi-Fi networks in the region.
The development and expansion of wireless technology brings us not only benefits and mobility, but also risks. Widespread commercial use of the company's Wi-Fi wireless network has spawned the next generation of hackers for wireless attacks. Here we will analyze the main risks of wireless networks and how to minimize or eliminate them.
First, you should know that traditional cable networks use wires to transmit data. They were protected by several serious means. The first line of defense is the physical boundary of the building where the network is located. Other defenses are firewalls and IDS / IPS traffic analysis systems.
Therefore, if the hacker wants to achieve his goal, he will have to dive into the building and connect directly to the network, or break through the firewall. Wired networks are better protected than wireless networks, as we will see the facts later. However, due to improper use of wireless networks, even these networks are easily broken.
