I only ask because where i live the paging system frequency is close to Infrared but unlike Inrared frequencies which bounce of the ground surface, the paging system frequencies are known to penetrate hills. The only problem i can see would be making instead of a IR LASER to change the frequency and make a MASER. What's your thoughts?

what's that stuff you say ???
first of all Esteban is not here to answer, it's some time that he do not post here...
then what's that exchange you made ??? IR and microwaves are not same thing... then , how to say that... I think either ways don't work
