[RF-ISM band] ISM is an acronym for Industrial-Scientific-Medical and consists of unlicensed spectrum (meaning you don't need a license to broadcast in the band providing you meet FCC rules for output power, modulation technique)at 902-928 MHz (mainly cordless phones and intercom), and 2.400-2.4835 GHz (mainly wireless LAN's--see IEEE802.11 standard for more info), and 5.725-5.870 GHz (mainly wireless LANs). Each has its pro's and con's. For more info, search for: wireless LAN, ISM wireless, IEEE802.11.
I would disagree that wireless will only be a small niche player. 10MB wireless LAN's operating in the 2.4G and 5.7G bands exist today, and it's a matter of creating demand to drive the costs down. Right now there are HUGE profit margins in these products, so costs are high. If the cost reductions don't happen, these folks missed the boat in my opinion. Many people either don't want or can't have a cable infrastructure retrofitted to their homes, and the wireless option is very attractive.
Also, you said: <<Control will be done via wireless NCs, including
mini-NCs that will function much like today's remote control devices although with mini-displays for status readout.I believe that if you really understand NCs, you will realize that this is the future, and it has big consequences with regard to understanding the
way in which LANs are going>>
First, I definitely don't understand the big attraction w/ NC's, but haven't really given them that close a look. Hey, you can't follow everything, and for whatver reason, the topic hasn't interested me. By all means, give us your "NC pitch"--convince us. Second, please explain your scenario for NC's as the "command and control" center. It seems like that would be immense overkill for conveying control sequences to turn down the volume, change the channel, etc. Also, please define a mini-NC, i.e. what's in it.
thanks,
