Now, a cellphone detector to nab cheating students
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 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. With a battery life of about two hours, the device features an integrated multiband antenna that is hidden under the label. The receiver continually scans all cellphone bands and utilises a sophisticated algorithm to distinguish real cellular activity from ambient RF noise.
