Isn't that the fallacy that car salesmen use to sell overpriced extras. "If you're already spending $20,000 on a car, what difference does a $500 stereo make?" The complicated mixture of wireless networks might be cheaper than fiber. Looking at it another way, why would anyone use wireless for a fixed installation when they could "just" lay wires around their house or up their street. They're already built an expensive house or street.
