Spectrum analyzer catches exam cheats in Taiwan

Police in Taiwan 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, a first case of its type, the equipment maker said on Wednesday.

Officers used three FSH4 analyzers specially configured by the German manufacturer Rohde & Schwarz to monitor an exam in south Taiwan for prospective government workers, said senior company engineer Lai Cheng-heng.

The handheld devices are normally used to help telecom companies check the strength of phone signals, but Taiwan's National Communications Commission had asked the designer for a special order aimed at catching exam cheats. (more)
