Does anyone know of a circuit that will block mobile phone reception? A pink
noise generator in the 900Mhz area presumably will do it. Alternatively a
sweep generator covering that frequency. A range of 25 to 30 feet will do.
Reason. A friend of mine teaches at a tech college. Despite being told to
turn them off in class, certain students are continually chatting on their
phones and sending/receiving text messages. (Discipline in class is a joke
these days) A short range jammer/blocker should solve the problem.
Any circuit information appreciated.
