perhaps you know how to build a frequency jammer

The first jammers were developed by the military and used for communication purposes.These days, young people use mobile phones regardless of the occasion and do not understand politeness. Use a wifi jammer to send signals at the same frequency. The cellular signal area is disabled to prevent unpleasant conversations.Currently, smartphone users are increasing every day. By comparing electronic devices with WiFi signal interceptors, wifi jammer are becoming more and more civilian, and these devices disable phone signals in certain locations.

For different wifi jammers, the jam range described in the manufacturer's specifications may differ from the actual working range. The interference range is affected by factors such as transmission frequency, working environment and battery life.There are various types of cell phone signal blocking devices on the market.If you want to shield signals over a wide range, you can buy expensive high-power jammers.How To Build A Frequency Jammer.Such high-power interference products have a wide interference range, and a large number of antennas are installed.You need to consider the frequency and range of the interference.

I think there is enough work space, and the easiest way to stop talking on a mobile phone is to use a blocking device. Radio frequencies, radios, radars, and cell phones can be interfered with, and strong radio signals of the same frequency can interfere with it.Used to control enemy communications.If WiFi interference products are placed surrounded by tall buildings, the actual blocking range of WiFi radio suppression equipment will be reduced. Of course, your budget will increase. You can find the information you need on the Internet.
