Cheaters beware! A US-based company has developed a portable cellphone detector that vibrates and lights up each time there is a nearby transmission from a mobile phone,making it possible for teachers to catch a cheating student.

The gadget called Pocket Hound works by lighting up if there is a mobile phone transmission – a sign a cheater could be in action.

Once the device is set off,teachers can nab the offender,manufacturers said. The device has a battery life of about two hours and features an integrated multiband antenna that is hidden under the label,’Business News Daily’ reported.

The receiver continually scans all cellphone bands and utilises a sophisticated algorithm that constantly samples the radio-frequency (RF) noise floor to distinguish real cellular activity from ambient RF noise. The gadget has been developed by Berkeley Varitronics Systems and costs USD 500.
