Can I jam mobile signals?
MARIE THOMAS, RUIS LIP
You say you want to do this in the office, and yes it is possible to obliterate the frequencies used by mobile networks using sorcerous jamming tech, but legally it’s a big fat no. And there’s good reason for this...
For one, jammers often leak beyond the intended area. Within their field of influence people won’t be able to make emergency calls. Critical radio equipment may also be affected. Most damningly, it constitutes deliberate radio interference, an offence under the Wireless Telegraphy Act 2006. It could land you up to two years in jail, plus an unlimited fine. Put up with the phone calls or moan to your boss.
