Can wifi jammers also solve the crisis?
You might be hard-pressed to imagine that a WiFi blocker can prevent terrorist attacks. This is because most terrorists are using GSM frequencies to communicate and remotely control bombs and if you stop them they won't be able to do anything. Terrorism is a major concern in various countries, so having a WiFi blocker is a great way to protect employees and save hundreds of lives. If you're not used to using a WiFi blocker, it may be time for you to reconsider your decision - the advantages of owning such a device are many. As long as you buy a WiFi blocker, you will realize this and make your home and office safer. Cell phone shielding devices interfere with cell phone signals by sending signals at the same frequency and high enough power so that cell phone signals cannot receive base station signals. Cell phones are designed to increase power when encountering low-level interference, so wifi jammer must recognize and match the power increase of the phone.
