Eric, you probably know a bit about capacity at low frequencies. Higher frequencies are used for mass communication because there isn't capacity at low frequencies. Frequency reuse in smaller cells is essential to provide capacity. It's also more efficient to send signals around the world by fibre than by omnidirectional bouncing off the ionosphere. With fibre, just a short low energy wireless hop is needed from where you are to a fibre access point. Well that's my professional background. RF.... DC thru Light frequencies and even above that. My communications system is not reliant on infrastructure like the WWW is. When disaster strikes mine always works! That's the beauty of it. In areas wiped out such as in hurricanes we step in during the early response phase and are part of the first responders. Cellular systems have very rapidly run out of spectrum and this a very big problem with the industry now. A "fixed" amount of room. Putting cell sites closer together creates other problems for frequency reuse. The frequencies available for Cellular usage is very restricted. Path loss, folage attenuation and other propogation factors limit the freqs that can be used efficiently for cellular. After all.... there are a LOT of other users of the RF spectrum that existed before cellular systems came out in the late 1980's. Eric
