jammer-mart.com high-end cell phone jammer has the following features, and is designed for school-developed products. At the same time, it considers the special use of school-specific signal interception equipment for school use. The built-in antenna design eliminates the possibility of students damaging the antenna, and avoids the trouble of the spiral antenna. The shielding range is accurate and the interference ability is strong.
There must be interference between the source and the voyeur detector sensor to complete the circuit, conductivity, and interference signals. The electromagnetic wave radiation of the connection circuit is transmitted through the medium. The electromagnetic field is transmitted according to law. The interference energy released into the surrounding space will Transmitter transmission. Computer security equipment, a processing device that exchanges information during the exchange of many generated data, and a leaky form of processing information and video data, copiers, printers or similar, electromagnetically conducted signal jammers.
These mobile phone jamming devices can be used alone, easy to install, small in size, electromagnetic compatible, and can use the network. The network can protect the entire area only with partial protection in standalone mode. It mainly interferes with GSM CDMA 3G 4G WIFI GPS and other frequency bands, and the interference effect is very good.
