Catching Exam Cheats With a Spectrum Analyzer
angry tapir writes "Police in Taiwan have used a set of spectrum analyzers to catch at least three people suspected of cheating on an exam by monitoring them for mobile phone signals. Officers used three FSH4 analyzers specially configured by the German manufacturer Rohde & Schwarz to monitor an exam in south Taiwan for prospective government workers."
I live in Taiwan, and at any exam that I have ever attended there is one simple rule. If your cellphone even as much as vibrates while you are taking a test you are disqualified at that moment. We are told this beforehand and are recommended to turn off our cellphones.
