OperationJamming devices overpower the cell phone by transmitting a signal on the same frequency as the cell phone and at a high enough power that the two signals collide and cancel each other out. These places include worship places, university lecture rooms, libraries, concert halls, meeting rooms, and other places where silence is appreciated. Nowadays the mobile jammer devices are becoming civilian products rather than electronic warfare devices, since with the increasing number of the mobile phone users the need to disable mobile phones in specific places where the ringing of cell phone would be disruptive has increased. This interest comes from the fundamental area of denying the successful transport of the information from the sender to the receiver. Where tactical commanders use RF communications to exercise control of their forces, an enemy has interest in those communications. Up to four frequency bands, including all cell phone tapes.IntroductionA MOBILE Jammer is a device that transmit signal on the same frequency at which the MOBILE system operates, the jamming success when the mobile phones in the area where the jammer is located are disabled.Ĭommunication jamming devices were first developed and used by military. RF signal jammer over a range of up to 40 meters Power supply: AC adapter 110-240 AC or DC 12 V - 36 V / 3 AĬooling system for constant operation 24 hours a day, 7 days a week. The device can be used in homes, cars or buses with the AC 110-240V and DC car charging adapter It can be used on any frequency system of the global network.

This jammer is used in some places where mobile phone signals are not allowed for security reasons, such as oil and gas storage facilities, oil and gas fields. TG-101A Cell Phone Signal Blocker (CDMA / GSM / DCS / PHS / 3G) is a high-tech product, which is specially designed according to the mobile communication situation in France and abroad.
