Hello Dan, (and others in the group)
A question about something I have been thinking about.....
If BPL seems to be intended to be offered at a price not too much different
that DSL or Cable connections, why are we (or any representative groups)
doing presentations with the companies that offer Cable/DSL services??
Seems like those companies are the ones in direct competition for service.
Since Cable/DSL isn't offered EVERYWHERE but is offered in most areas, as
BPL (in theory) would also be available in all areas where there is power
lines, it seems like the BPL folks could sell to those who necessarily are
NOT in the rural areas too.
The present-day Access BPL test areas ARE in urban areas, not
rural. That's where BPL will have the best chance for revenue.
Also, what about commercial broadcast such as AM radio?? In my area alone,
power lines radiate a TON of interference already BEFORE BPL. If a
broadcaster truly knew that their signals weren't as effective as they were
before BPL, they might also want to get on the anti-BPL bandwagon.
Access BPL is reputed to operate above the AM BC band and
stop just before the low end of the FM BC band.
Some of the "VHF channels" of U.S. TV will get the high end of
BPL interference. However, many of thpse VHF TV channels will
be moved once the cut-over to DTV is complete.
The FCC presently has another NOI open on using those open TV
channels for broadcast broadband data.
The FCC has NEVER been aggressive on making electric power
companies cut out their RFI from power lines. That was before any
BPL or PLC was devised. It hasn't changed.
Lastly, what about emergency services frequencies? From what little I do
know about BPL, the frequencies and their "possible" harmonics could affect
their frequencies, at least to interfere with their repeater systems.....
Police and fire chiefs have alot of pull, especially when they get together
in groups.
Several groups have "spammed" the FCC with their Comments on
this and the interference to already-established emergency services.
[Rev. Jim calls all such Comments for "spam"]
The major BPL RFI effect to emergency services is on the "low
VHF" PLMRS at 30 to 50 MHz. The "high VHF" PLMRS band is
relatively unaffected by reputed Access BPL bandwidth.
Just some thoughts on the issue....
Good thoughts on that! APCO was concerned last year and still is.
A few other groups have "spammed' the FCC on the subject and all
are visible to the public at the FCC ECFS, docket 04-37.
