FEMA Opposes Broadband Over Powerlines 346
Curmudgeon Rick writes "According to eHam.net, the Federal Emergency Management Agency has put a submission to the FCC strongly opposing the use of powerlines for broadband distribution. The report can be found here [PDF link]. IMO, vendors should let powerline broadband die. They keep defibrillating it only because of the dollars they poured in; but it is and always was a dead duck." The submission concludes: "FEMA has concluded that introduction of unwanted interference from the implementation of BPL technology into the high frequency radio spectrum will result in significant detriment to the operation of FEMA [emergency] radio systems such as FNARS."

The economics of rural service are very interesting. Right now everyone with a phone in the USA is paying to subsidize phone access to rural residents. It costs more money to service an area with a low populations density than an urban area. Fine, people need phones for safety reasons. Rural residents presumably subsidize services they don't need, like meth clinics.
It bothers me when people start talking about subsidizing rural internet access, though. El says that "they're not even thinking about running cable" near his house, and that he'd have to shell out 10K$ to connect to said cable, anyway. I'm curious: who does he think should bear these costs? Everyone in the US?
If people want to move to the middle of nowhere to get away from gangs, traffic, comedians, literacy, and culture, that's fine. It isn't reasonable to expect the same service level in the middle of nowhere that one enjoys in New York City, though. It's especially unreasonable to regard the acquisition of these services as a right. If you want to enjoy cheap services, then move to where it is cheap to provide those services. If you want to live in an area that is difficult and expensive to service, break out your wallet.
El isn't necessarily making this argument, he just reminded me of the people I had to deal with when I worked in the rural NW.

1 - vendors come in, offer to pay for the infrastructure in return for exclusive rights to it. If you refuse, they ignore your town indefinitely (AT+T did this here when they owned the local cable company). Anyone approaching these vendors about subleasing access gets quoted insane prices ($20k per month to use an existing cellphone tower for an 802.11b antenna, in one case I know of).
2 - There are restrictions on putting cables onto poles. These range from weight and rain/wind/snow load design issues to vertical/horizontal clearance restrictions. Imagine being responsible to safely/quickly work on one of 25 cables (including data, fiber, and *power!*) on a single power pole and you start to see a worst case scenario.
3 - Each new cable needs full engineering, documentation, and 24x7 support staff.
4 - Buried lines are not cost-effective to piggy-back, so areas without poles are inaccessible.
5 - These aren't communications/IT gurus that are being asked to make these infrastructure decisions. They're politicians, planning and zoning staff, and a few Electrical Engineers (Power, not computer/communications). The learning curve to doing a good infrastructure with a 25-year expected life is nasty enough without this handicap.
6 - The existing owners hate complications. Power company doesn't want the liability/hassle, or phone company doesn't want the competition.
7 - The cost of cabling, repeaters, etc: let's say roughly 100 lattice lines per square mile x the area of your city. I dunno where to even look it up but I'll estimate cable cost installed at a buck per foot. And I'll throw in ten grand per square mile to handle the electronics. That's some serious cash, and I wouldn't be surprised to learn costs were much higher.
So, it isn't that the ideas aren't out there. There are even some *more* clever devices (little fiber-retrofit robots 'stapling' the fiber to the top of sewer pipe). But it's not cheap, it's not easy, and once those two concepts (hard and expensive) join forces, it becomes risky politically. Much riskier than doing nothing.
Of course, a lot of communities just nodded gratefully when presented with option one (where the town agrees to perpetual rape-n-pillage unregulated monopolies by a single vendor). Ow! Thank god for the multiple-headed threats of: powerline broadband, dsl, cable modems, wifi, cellphone wireless, and beyond, because that keeps just enough competition in my area to hopefully nudge cost-per-gig down. Hell, I left the above meeting intensely angry about the learning of the city's agreement to one such infrastructure monopoly, since there are hundreds of local IT geeks that would have volunteered to design things to eliminate/minimize a monopoly like this.
Disclaimer: These are all 2-year-old impressions of things a bit outside my area of specific experience. Actual details may vary widely, no warranty given. But the above was enough of an eye-opener for me to give me a greater respect and fear of the last mile problem.

And while we're at it, let's require that the laws of physics be re-written by Congress! You just don't understand what we're talking about. Power lines are great for low-frequency AC (60 Hz power), but inefficient for higher-frequency signals.
The proposed Broadband over Power Lines service would be a shared user of frequencies between 2 MHz and 80 MHz. Again, these frequencies wouldn't propagate as well over power lines, so they would be sent at high power levels. Much of their energy would be lost in the transmission from the upstream connector to your home -- i.e. radiated out the miles-long antenna formed by the power line! Simply put, you CANNOT have non-interfering BPL if it uses the 2-80 MHz spectrum. Period.
FEMA and other governmental users' radios are scattered between typically 2 and 50 MHz in different sub-bands that are used depending on the time of day, how active the ionosphere is and the overall path of intended communications. Ditto for fixed services, land-mobile, aeronautical and marine services, beacons, short wave broadcasters and amateurs.
The problem is two fold:
1) anybody trying to receive a signal between about 2 and 80 MHz would be unable to do so.
2) Legally-licensed transmitters in that range would cause untold interferance to these "Part 15" devices. Part 15 means they can't legally cause interferance and must live with any interferance they get. Aunt Millie's not going to be happy when her cordless phone is rendered useless by broadband and Uncle Phil will be pissed when he can't surf porn because the clean and licensed 1000 Watt transmitter up the block is on the air.

Iterference would be a huge problem fo HAM operators and everybody who use HF/VHF. But the thing is interference goes both ways. So I think if deployed in wide area BPL would just really really suck. You power line infrastructure was just not built to be protected from interference. Any kind of it. Even people with DSL have problem with intereference. And that's CAT3 UTP (in most places).
So for telco and cable providers BPL will just awake an apetite of more people for broadband. If you ever had broadband (however bad it was) going back to dial-up is just painfull. Most of my firends who installed and had problems with DSL just switched to cable. I don't even remember anyone of them fireing up their dial-up modem ever again.
