There's a version of BPL that uses the microwave spectrum. Hopefully
this is that.
Bad news for our microwave hams, but not so bad for HF users, if true.
1Mb over

For quite a few years, the phoneline networking standard has been
delivering up to 10 Mb/sec by using a residential telephone line
(http://www.homepna.org/products) to carry a fraction of the HF
spectrum.

1 Mb/sec seems to be *easily* achievable at HF. It's already
been done.

Sorry. One Megabit data rates over "residential telephone lines"
that INCLUDE already-installed telephone cables and switching
centers in the transmission path is NOT a given everywhere.

Higher-than-1-Megabit rates are possible with "category" cable
and special terminal transceivers for IN-Home networking. That
is NOT the same as the BPL under discussion.

I couldn't find any modems or other devices in that site which involve
Internet access or even WAN netorking via the power utilities'
existing infrastuctures. Or they went over my head. Kindly clarify if
you will.

Where? By what means?

The way I understand the matter real-world commercial tests of BPL
have demonstrated (so far) that, for all practical purposes, Internet
access via BPL is delivering only around half the speed common DSL
does for a bunch more dollars per month for a connection.

The $29.95/month cost is just another bait & switch scam, the cost
goes up to around $50/month after a few months for half the speed of
DSL for $30-40/month.

There are a number of approaches for using the microwave bands to
provide Internet access under discussion and development. Commonly
referred to as "802 dot something" (take yer pick and buy their
stock).

But those are not BPL which is defined as Internet access over the
elecrtic utilities' power lines which operate in the 2-80 Mhz portion
of the radio spectrum. I've personally tuned the HF spectrum in a BPL
pilot area and no, it's not just "so bad" it's bad enough to kill HF
ham radio anywhere the crap is deployed.

Probably.
