You anymore don’t need to be worried about the irritating phone calls of others while you are at public place watching a movie or is in between of an important business meeting. As people are reluctant to switch off or keeping their phones in vibration mode despite instruction, you can tie them down by using GSM cellular network jammer.

An average GSM Cellular Jammer with 45 watts transmits happens to be strong enough to block GSM signal with upto 120 meter range that is more than sufficient space to cover without any public issuance of switching off a mobile phone.  Other unique feature with this Jammer is that it can be used in specific direction using a uni-directional antenna without affecting any other users near by to transmitter. Four fans added to the transmitter can release out unnecessary heat emitted out of the equipment.

This device by any mean is not a cheaper identity, instead is provided on price of £2875 and is apt for an enterprise usage to block unwanted signals. To the public notice due to certain regulations, use of this jammer is prohibited in some countries.
