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."
Wow, those R&S analyzers are some serious tools! I was just looking at frequency analyzers over at DealExtreme, where they have a dirt-cheap handheld model that sniffs out cellular frequencies for $60. Or they could have hung a cell jammer in the room for about a hundred. Or if they really thought they had to have the fancy gear, they probably could have hired in a contractor who would have sniffed around for maybe $300 per hour, and known what he was doing.
Was it was really worth the $40,000 they probably spent on them?
Oh, that's right. It's a government organization. Spending money is in their job description.
