cell phone jammer - nonsense?
most companies do not allow use of cell phones but fight a lost battle since after "cabin secured" passengers still use them during most critical phase of flight when only action of cabin crew can be "please switch off...".
many times I thought we either should give up completely on this one or use jammers but of cours these would disturb even more...
since passenger planes transported cell phone controlled bombs I ask myself even more about use of jammers - maybe they could even be certified for use in planes.
what do you think - maybe you have an idea whether "harmless jammers" are technically possible or not...
