Hi John: As usual, I didn't make myself clear. I meant in the air. I know that there are probably problems with diffusion over distance, but I was also guessing that it might be difficult to keep hundreds or thousands of parallel beams from interfering with each other. I am under the impression that these beams can be made very small in diameter, so conceivably very many of them could be transmitted in parallel with a very small aggregate diameter. So the questions are, how many could fit in how small an area without creating interference and, I suppose, how far will they go before diffusion starts causing them to interfere with each other? If it is possible to do this fairly efficiently, I just thought that it might be a viable way to do extremely high bandwidth wireless data transfer, at least over short distances. For all I know, this is being done routinely as well. I have just never heard of it. Thanks for hearing me out.
