Re: Is Low-Cost Wi-Fi Un-American?

Even with the most enthusiastic of outlooks for spectrum reuse and advanced
wireless systems, wireless BB will not deliver similar bandwidth per user,
particularly over large areas/distances.  Fiber is it's own very high
frequency spectra media that has little of the interference bottlenecks to
deal with and much wider basic media bandwidth available.  Wireless systems
big advantage is flexibility, low cost of making connections and mobility.
I don't view WBB and fiber so much as competition as complimentary: fiber
optic is an ideal backhaul and metro grid network that can be used to
support the various wireless systems as well as, were it makes sense, being
driven into the home/premises.

As a general rule, the more fixed a consumer device is, the higher bandwidth
needed to support it.  Some question whether there will be a mass market for
unmettered broadband to fully mobile devices: how much resolution is needed
on a cellphone screen or while you are walking or traveling down the road?
Perhaps the needs will be more for what you can send uplink, (video) than
down.

ART tried doing this as well. It was a cool idea, but you can barely
make enough on metro fiber rings as it is.  Also, microwave cannot even
match the reliability and capacity.
