Many radio stations would like to reach a broader audience, but, due to limited range of radio signals, they will not reach their intended audience across the continent or such. thus, i want to make the signal more powerful, of course. If we were to use connected radio beacons like they do with the airways, we could easily and cheaply send our signals anywhere. if we were to use these beacons, they will connect the whole world from chile and argentina, up towards alaska, across the bering strait to russia, down towards south korea and into china, down towards indonesia and australia, and across into the near east and egypt, into europe and africa too, ending in cape town for the greatest distance by land. This would be cheap simple and easy, of course.
Or they could simply use the Short Wave band, which is almost global depending on weather conditions.
Better and cheaper are the new radio digital mediums requiring much less power ( 5 watts RF per cell ) peer interaction, it Originally started out in ham radio, a global commercial, but peer driven cell system.
