Wireless service providers think they can compete with fiberoptics not just over the long haul between financial centers, but within a metropolitan area as well.
fac: Petere, you may recall the by-the-numbers exercise we ran on this subject two years ago, taking into account the nominal velocity of propagation of RF and glass; an extension of the approach discussed in this article, beyond WAN/ metro/ access, is the in-building hybrid fiber-wireless LAN; I strongly suspect that rooftop (and window-shot) based infrared systems employing a simple on-off modulation scheme are even more suitable than multi-stage RF systems, if nanoseconds are being measured and shaved...
