The cell phone jammer can block the signal of mobile phone. When it was installed, there is no signal in your cell phone.
Yesterday, I read a piece of news that a middle school have installed the cell phone jammer for there are many students play games or surf the internet with the help of mobile phone. Many people agree this point while others disagree.
But the main problem is a GPS jammer cannot be detected. Your phone will remain in poor signal reception if a Jammer is active in the area. The Federal Communication Commission of the United States (FCC) has control over broadcasting public telecom services.
The Perfectjammer will incorporate a suite of anti-drone solutions including RadarZero, a portable drone detection radar; RfOne, a drone detection device using an RF direction finder, a rifle-like counter-drone jammer. “The resulting product is believed to be a first of its kind — a non-military vehicle with a suite of counter-drone, multi-sensor, detect-and-defeat solutions,” a company press release states.
Perhaps you live in a part of the world where conflict happens. Perhaps you’ve noticed an increase in the drones in your area and want to do something about it. Thankfully, you can. For example, the Net Gun X1 is designed to be used by a wide selection of different people, allowing you to shoot down drones if they get too close to you and your premises.
Such technologies, which effectively render the satellites useless, make it difficult for any potential enemy to bypass the jamming and de facto leaves them without any modern communication tools. Eventually, it can significantly shift the balance in modern combat activities, which are increasingly characterized by rapid changes of environment and high requirements for troops’ adaptability, in which communication plays a vital role.
At present, the construction of jammers is being carried out, which will replace the” -22PP “woodcutter” aircraft “serving in the air force. The new jammer will have new equipment to carry out electronic interference suppression for any target in sea, land, land and air, and to scrap the enemy’s satellite for ensuring ground navigation and radio communication.
