Drones help detect cheaters on Chinese college entrance exam

June 12, 2015

China is using drones to combat cheating on its college entrance exam. The drones scan for signals that might be sent to devices sneaked into the exam by students. “A drone has its advantages. In an urban area full of tall buildings, various barriers limit the operating range of devices on the ground, while the drone can rise up to 500 metres and detect signals over the whole city,” said Lan Zhigang, from Luoyang’s Radio Supervision and Regulation Bureau. Cheating is reportedly very common on the exam, which can last for two or three days and is written by almost all Chinese high school students. CBC | Toronto Star
