((also posted to General Engineering)) Hi everybody, I'm working on a concept for a movie that I'm making. It's a fictional movie, but the concepts in it are definitely grounded in current and theoretical science. Coming from a big science background, I of course want the fictional technologies in the movie to be somewhat technologically feasible. So for the first concept: Could you transmit data from one point to another, or to one main base station of some sort, over a very low frequency such as 12Hz? * If not, why not? Is it just a horrible frequency to transmit at? What would be the reasons it would not work? * If not, are there any technologies, whether current or theoretical, that could make a low frequency like 12hz viable for data transmission? * If so, how efficient would it be in comparison to (for example), transmitting at 1900MHz (a frequency used for US GSM signals)? * Any thoughts overall about transmitting data at very low frequencies? If anyone interested could post their thoughts on this, I'd really appreciate it. Once I get some feedback I'll of course post what the conept actually is. :) Thanks in advance everyone!
