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."
TFA says it caught them cheating. It didn't say they were disqualified. For all we know, cheating may have been a prerequisite for a gov't job.
