Ringing mobile phones, the scourge of restaurants, cinemas and commuter trains, are finally to be silenced.
C-Guard, a device developed from Israeli military technology, can detect mobile phone rings and jam handsets within 100 yards via a chip that monitors transmissions. When it detects them, it transmits a rush of static on exactly the same frequency, which neutralises the phone signal.
The device also guarantees you don?t get lots of red faced mobile phone users screaming abuse in, for example, your restaurant. The phone user is actually unaware that their mobile is jammed as the display on the handset will simply read 'no signal found'.
C-Guard is being launched in the UK next year by Netline Communications Technologies. A few alterations will have to be made to it prior to its release to overcome possible legal barriers, which restrict jamming devices in the UK.
At nearly #800 the device does not come cheap, but Netline believes it will appeal to leisure complexes and restaurants as well as hospitals, where mobile phones have been known to interfere with sensitive monitoring equipment.
The irritation caused by mobile phone usage in public places is definitely set to get worse - there are now more than 10 million mobile phone users in the UK and the market is booming.
