A Hong Kong company hopes to sell signal jamming technology, previously used by the military to thwart lethal missiles, to block annoying cell phone calls in places such as hospitals, places of worship and restaurants. "This is a way to enforce the etiquette of mobile phone usage where polite persuasion has failed," Paul Kan, chairman of Champion Technology Holdings, said at the launch of its MuteTone product on Wednesday.
Champion, which has modified the device for commercial use, hopes to sell the mobile signal blocking device in about 50 countries. The device sells for around $1,600.
The response from would-be customers so far has been encouraging, Kan said, although Champion has not yet been able to surmount regulatory hurdles in its home base of Hong Kong.
