Jammer, which initially sounds illegal, is that not all jammers are used for illegal purposes. Many of them are for legitimate purposes. What is the wifi jammer, what are the application examples of the WiFi jammer, and is the WiFi jammer legal?
What is a WiFi jammer? The jammer transmits the same frequency as the signal to be interfered. If the signal sent by the jammer is stronger, the original signal cannot be used, or it becomes more difficult to connection. The WiFi jammer means that the exchange of data packets is restricted or inoperative, so that the data streams cannot be properly combined and the WiFi network is shielded.
Jamming is very common in radio technology. Even today, WiFi networks are very common, WiFi networks transmitting on the same radio channel will affect each other, so that the entire network speed is stagnant. As long as the machine does not shield the interference of the radio signal well, the number of transmitters will always exist and increase.
WiFi jammer is common in private homes. When it works, it can block the WiFi network at home, so that children can spend more time learning, communicating with their parents, entertainment, etc., instead of putting most of their energy into online games, and also preventing others from stealing their own internet. This sounds like a fun and meaningful thing.
Having a WiFi jammer is not entirely banned. In prisons, WiFi jammers are very useful. They can prevent dangerous elements from communicating with the outside world, so as to avoid jailbreaking, drug trafficking and other transactions. In some casinos and gambling halls, they have been using mobile phones to operate slot machines for a long time. For casino operators, using such equipment will be a legitimate benefit.
Where can I buy a wifi jammer? The WiFi jammer is a small device. Some mini- and low-cost WiFi jammers are very common and inexpensive. They can be purchased at the jammer-shop website, and the price ranges from tens to hundreds of dollars. For an electrician with some experience, making a jammer is not a big obstacle.
