Andrew Tanenbaum makes another of those points in his "Computer
Networks" is responsible for another such (this in a ref to a diagram of
the electromagnetical spectrum) :
it should now be obvious why networking people like fiber optics so
much. df/dLambda = -1 * (c / (lambda*lambda))


Which basically says that people who believes wireless
radio-telecommunication can compete against optics in pure thruput is
smoking.
