You're being too nice. In my never humble opinion, municipal Wi-Fi is
a really awful idea. Massive municipal Wi-Fi and mesh deployments of
the size proposed by Earthlink have serious technical issues. The big
problem is that such large Wi-Fi systems do not scale well. What
works just fine for a small deployment, doesn't necessarily work the
same way with a massive deployment. There are also problems with
latency through too many hops, geographic routeing, cold spots[1],
lack of indoor coverage, interference, hacking, security, abuse,
maintenance, vandalism, reliability, general lack of support, ad
nasium.
For the cities, there's also no compelling revenue generating or
savings incentives. It's like when credit cards first appeared.
Nobody wanted to pay for a credit card because no merchants were
accepting them. So, the credit card companies had to run at a huge
loss for quite a while and literally give away cards and merchant
accounts. They were eventually saved from bankruptcy by the banks.
It's the same with muni-wireless. Very few are going to pay for a
wireless subscription without adequate coverage, decent performance,
and reliable service.
I figured (i.e. guessed) that Earthlink would get in over their heads
after some major deployment demonstrates what can be easily calculated
on the back of an envelope. I hadn't expected them to throw in the
towel quite this early. Scaling back really means "trying to wiggle
out of the contracts" and avoiding getting sued by the contracting
municipalities for breach-o-contract.
Anyone wanna take a (small) bet that Earthlink magically discovers
WiMax as a replacement for municipal wi-fi? Their partnership with
Digipath didn't exactly work as expected, but it's the only real
alternative for Earthlink as Wi-Fi has problems, dialup is dying, and
broadband cable and DSL are already monopolized. The catch with WiMax
is that it really only solves the technical problems. It does nothing
for the administrative, political, and financial problems.
