Most jammers generally work by pumping out garbage on the same frequencies that cell phones use (or all frequencies if it's a cheap device)

So in most respects it's transmitting a signal. Depending on the radius you want to cover you may or may not need a license from potraz.

I would assume that potraz would likely deny most requests that don't have good grounds for having such devices In use

I should also add like the other answer the nuisance factor it may cause in heavily populated areas and the possibility of it affecting other signals eg tv/radio and possibly even satellite as well

i was thinking of using it within church confines, say one that transmits a jamming signal within 50 feet. ringing cellphones are a nuisance in church.

education would be better really - ie remind people to switch phones off or to silent - people may need to use cell phones for genuine issues/problems and jamming them could be bad for them

despite education, reminders, "cellphone-use-not-allowed" posters on walls you still get to the phones ringing.

ouch - i would double check with POTRAZ first - its very very likely that jammers are explicitly banned without licenses because of the potential misuse

There is one law that can capture you. Being a public nuisance.... besides you are beaming signals aren't you? Then you need a license with Potraz. However I saw a college library using one without a licence to block cell phone calls... so I guess there are loop holes

actually, the public is the nuisance here, forgetting to turn off or to silence their cellphones in church services
