You cannot 'break' a cellphone connection, the same way you cannot, say, break the connection between a broadcast transmitter & a radio/television. The only way to stop a cellphone from working would be to have a signal source on the same frequency as the downlink btween BTS & MS, & of a greater power level. For it to be a convinient size (i.e. battery powered, ~100mW), you would have to be very close to the offending phone. The further away from the phone, the greater the power needed.Also, in most cellphone frequency allocations, there are about 1000 channels, in some cases the BTS to MS link will actually frequency hop.so in other words forget it. It is technically not feasable to jam indiviuals mobilephones. It is also illegal.If you are in a cinema/concert hall, then speak to the management to put signs up. If you're just in a street, then live with it. Mobilepholes are part of everyday life now, so grow up.
