Just to add, Think about how our communications technology started... More power to reach farther. Not look at how technology has morphed through time to provide a more portable medium. Because of this, portable power now becomes a much more important commodity and communication EFFICIENCY becomes the primary driver of RF technology. as a result the Earth was noisy for a bit before becoming more and more quiet.
