Unfortunately it's not just telecoms companies that are at fault. Even within our industry we have come more and more to rely on radio systems. The number of shows that used to go out with little or no radio systems, now IEM are common place as are radio mic's. Possibly, in the past, we avoided such as the gear wasn't that great and there were significant trade-offs in terms of sound quality and reliability. Major theatre shows often have 40 + as we all well know, major television events can be considerably more, seems like the world and his wife want to be wireless these days. Being that broadcasters do have relatively "deep pockets" and airtime influence, I suspect that in real terms compromises will be reached. Perhaps necessity will drive the next quantum leap forward in technology and the radio systems of the future will be better than anything we could dream of now?
