Nobody's denying the popularity of wireless. The question is whether its
capability is comparable to a 100 Mbps FTTP solution. I say no; the
Shannon-Hartley theorem says no; even some of the wireless vendors
(Ericsson is on the record here) say no.
What frustrates me about the wireless-versus-fibre discussion is that
it's unnecessary. There's no reason to treat the choice as exclusive.
The cellular base stations will benefit from ubiquitous fibre anyway.
But saying "skip fibre, build lots of base stations instead" gets the
wrong end of the stick, in terms of network performance, network cost,
and energy demands.
One reason - not the only, just one - that some people are willing to
skip the fixed line is because of the hassles involved in moving (given
the highly mobile nature of about 10% of people). But if the fibre is
there, and there's no conflict of interest getting in the way of
relocation / activation, would their behaviour remain the same?
