that is great for long haul stuff, but the purpose of bpl is for the 'last
mile'... getting from a service point like a phone central office to the
home. while it would be nice to run coax or fiber to the home it would be an
extra expense for the providers... with power lines going everywhere they
don't have to run extra wires on the poles or underground.
what amazes me is that they think there is enough demand for this type of
service to make it economical. there are a couple factors in this that i
would think would make it less attractive, first many of the more populated
areas are already served by one or more broadband services, either dsl or
cable tv systems cover a good percentage of the country (by population
anyway). i live in what i think is one of the last 2 towns in massachusettes
that doesn't have a cable tv system. then there is the satellite internet
access that covers everything else.
and for those more lightly populated areas that don't have cable tv system or
dsl access there will be added costs of the devices to bridge the bpl past
each transformer between the injection point and the subscriber... this is not
just an automatic thing where the power company plugs in something on their
end and the subscriber can just plug in a box and have access... every
transformer along the line, including the one at the subscriber's home, has to
be bypassed to get the signal through... and then there are the distance
limits, amplifiers, probably fixing bad insulators and lightning arresters,
etc, etc, to reduce noise and get decent signals. i have a feeling that there
is a big lobby of bpl equipment providers that is trying to drum up business
that may end up falling flat on its face.
