story category Manassas Tries To Keep Dying BPL Network Alive
BPL industry's poster child for technology now on life support...
(old news - 06:13PM Thursday Apr 16 2009)
tags: business · alternatives · BPL
Manassas, Virginia was the first US city to see a real, non-trial launch of broadband over powerline (BPL) technology. However, BPL has floundered the last few years because of its inherent potential for interference with amateur and emergency radio, its irrelevance in the face of next-generation speeds, and the unavoidable fact that many utilities simply didn't want to be broadband providers. After buying the flailing network, city leaders have the network on life support, and are considering pulling the plug:
During Monday's meeting, council members budgeted and appropriated the $77,500 needed to fund the Internet service through June 30. . .City officials have spent the past few months analyzing the system and whether it is a good investment. Proponents say it is necessary to continue funding BPL because it provides economical Internet service -- about $25 a month -- to residents, some of whom are under served by telecommunications companies.
Given that BPL is likely going the way of the dodo, additional investment in the already outdated network probably isn't a good idea. Manassas was a particular hotbed of interference debate, with enthusiasts complaining the FCC didn't properly test the network and used bogus data to make the case for BPL. The FCC spent years cheerleading the technology a little too enthusiastically as the panacea to a duopoly they helped create.

Comtek, the company who originally built the Manassas network, has read the tea leaves and begun focusing on smart electric grid technology like Current Communications. Comtek was somewhat obnoxious when it came to complaints from ham enthusiasts in Manassas, claiming that interference didn't exist, and that ham groups like the ARRL were engaged in a "campaign to turn back the clock on broadband in the United States."

More Proof Government Broadband is Bad

So how do the taxpayers of Manassas feel about their valuable money being wasted on something that clearly isn't vital to the city to function.

I wonder if the same council threatened to cut funding for schools, police, firefighters and the usual suspects that come up when government want to raise taxes.

People in Manassas can get broadband from Comcast or Verizon (DSL or FIOS).

Both of these options were put in place with no taxpayer money involved.

There is no need for any form of government-provided broadband in Manassas.

Right.. Comcast and verizon and ATT alike only want the more populated areas.. What about people in less dense subdivisions? You going to suggest they move to get broadband? That reasoning alone shows ignorance and laziness amongst providers.. For company's that have had tax money handed to them already (( not stimulas money )) they have done a piss poor job coming up with faster and affordable networks for everyone..

Alright fine.. Clean out your guest room.. We all will move in to your place! When that is full, we'll get tents and move into the yard. Maybe we can build a structure over your house to help support all the extra people moving to the city from your answer.. Then when food prices sky rocket from farmers moving just to get utilities, and you start complaining.. Our answer will be move to the sticks and grow a carrot.

God seriously.. If you believe that's the answer, then you fail at innovation.. Sorry.. Hate it for ya.

Whose fault is it if you don't check to see if broadband is available before you move? Every place to live has its advantages and disadvantages. It isn't Verizon's fault or Comcast's fault if someone chooses to live out in the middle of nowhere.

Re: More Proof Government Broadband is Bad

Hello. I have lived in this area all my life.. Services were created and built out sense i've been living here.. Even though there are many people here wishing to have BB service from our local providers, they do not yet provide it.. There are quite a few of us.. Not just some farmer and his cow/goat/whatever he has..

Broadband not a utility? Heh, I think its more so than people realise... If you forget what its like to not have it.. Try dialup for a week.. I bet you won't last.. Just checking my bank account takes 5 minutes... God help me if I want to shop on the internet, watch a video, download software etc.... I love to play fps games, but latency just kills it..

Re: More Proof Government Broadband is Bad

I'll have to agree with some of this assessment, where I currently live was based on lots of research on the availability of broadband. Had it not been available from multiple carriers I would not of moved where I currently live.

I will agree on some of those forced to live in the boonies due to employment or some other factor, they should have multiple choices for broadband just like those of us living in cities. I'm about to be forced to live in the boonies and it looks like a monopoly on broadband services where I'm at (- satellite of course).

But unlike some other folks I was deployed to Afghanistan for a year and relied on satellite broadband to provide internet. Might not be able to play games but at least lets you keep in touch with folks and hop on the internet for other than latency applications without dial up speeds.

Other countries simply have higher broadband penetration than we do. That doesn't make it a utility.

And still no one has shown that people need broadband in order to survive, as one can make the case for things like water, power, gas, sewer, garbage pickup, etc.

Water is a utility... hygiene, hydration, and necessary for to maintain any other organisms such as plants.

Broadband on the other hand... watching videos, checking your bank account, and FPS games hardly compare.

Let me ask you this, is competition not good? Is consumers having a choice not good? Otherwise you get in to a situation of a monopoly, and we all know how that goes, price fixing, stagnant innovation, and basically a screw the customer attitude.

I think you should be more worried about why your hospital is charging you $20 an Aspirin than a build out of a public internet.

Of course all these things are good. But when it comes to paying taxes, unless you work for the Obama administration you have no choice in the matter. With taxpayer financed broadband, there is no choice, you must pay whether you like it or not.

In this day and age many state and local governments are claiming to be short on money. I am guessing that Manassas, VA is no different. If this is the case, then there are far more important things that this tax money can be used for other than worthless BPL, especially when the area has abundant options for "real" broadband.

True, but at least with most private monopolies, no one is holding a gun to my head forcing me to pay for something I do not want, either. If Comcast was my only broadband option and they stunk, at least I would be free to cancel and not pay them money.

With this BPL, it clearly stinks, and the taxpayers still have no choice but to pay for it.

I worry because if it was my town I would not want to pay for the latter. My taxes are high enough.

Re: More Proof Government Broadband is Bad

And what IF your taxes paid for a network that worked and actually was cheaper than what you currently pay for Comcast? BPL stinks you say? Really? Then why is it so popular in Europe? »www.devolo.de/de_DE_cs/spezial/d···al1.html where utility companies offer it at prices often cheaper than what they pay for dsl and faster speeds as well?

I would have NO issue paying higher taxes if the speed and service was better and cheaper, not by any stretch. Either way, it all costs dough, in the end, the best experience and best service is what I want.

The Power companies should be using their existing poles to string up some fiber, and provide FTTH, or at least some type of Hybrid Fiber-Coax (HFC) network technology.

Re: Just LET IT DIE.....

Most electrical companies are interested in smart grid technology and really don't seem that interested in being an ISP. There isn't much motivation for them to hang fiber. Heavily invested is a relative term. Have electrical companies really invested that much? Or have companies like Comtek spent the money attempting to get electrical companies to provide service, then dumping the systems on the taxpayers?

Are you suggesting that WiFi is a suitable option for next gen broadband? I equate WiFi to BPL prospects...it's a gap filler.

Re: BPL and Current(Cincinnati) implementation

I've read that Cincinnati's Current communications (link: »www.current.net/ ) implementation is Part 15 compliant - Is that true? If so, seems that technology could be a good fit for rural or small town service where the big ISPs aren't cherry picking.

I feel BPL in general is a stopgap technology and hope that eventually the playing field will be leveled to allow small operators and local governments to choose to build out their own services without being gouged for backbone access or sued into bankruptcy defending their right to build.

Re: BPL and Current(Cincinnati) implementation

BPL has NEVER been Part 15 compliant.

They routinely emit excessive signal levels on almost all Ham bands, and across may of the Public Safety BANDS AS WELL.

HAM radio is a licensed service under CFR part 97 Rules, and BPL emits excessive signal levels, on an Unlicensed Part 15 basis, on Part 97 Regulated frequencies.

They are breaking the law(US CFR:Part97), as written, and should thus be forced to forfeit fines, and penalties to the FCC for their infractions.

As well as Imprisonment for the intentional jamming of operators, licensed under Part 97.

Pay UP, and GET OUT.

Re: BPL and Current(Cincinnati) implementation

Thanks for the reply - I'd seen in this forum where this particular implementation was one that did not interfere with ham or public safety operations, and the gist of the post was that if Cincinnati can do it, why not others. I will try to find it again.

Personally, I support amateur radio and public safety and believe the BPL technology is not a viable one, that there are better ways to roll out rural broadband, so the ALL CAPS shouting at me isn't necessary

That's not true. There were several systems that exceeded Part 15 emissions limits, but not all did and a properly installed system should be Part 15 emissions level compliant.

But I should add that Part 15 emissions limit compliance does not prevent interference to licensed services. A system can be operating well below the emissions limit level and cause interference, in which case the "harmful interference" clause takes over and the system needs to reduce emissions further or cease operation.

Let's not muddy the water with misinformation.

It seems odd. The big companies say BPL doesn't produce interference, yet White Spaces provide a ton of it.

Seems a bit backwards to me. BPL produces a ton of interference and WS doesn't. I still want this proof they say that WS messes with broadcast TV.

What?? I have a few friends that use to talk to the Space Station, not to mention bounce signals off of the moon. I wouldn't be surprised if Ham operators found life on other planets.

Obviously you're not a Ham if you're spouting this nonsense. Who do you think we have to thank for most of the wireless technology today?

Hell, even Hams in the 80s had 56k (or faster) access around the globe using Packet.

I think if you'd go to a few Ham groups in your area that you'd shut your trap rather quickly. It's amazing how much knowledge they have of the entire spectrum and how to utilize it.

More than just hams!

There is far more than just hams operating in the HF band.

There is military covert, and overt, sea, land, and air operations..
International broadcasting.
International air traffic control. (airplanes crossing the great oceans.)
Ship to shore, And ship to ship operations. (you know, the radios that the people on deadliest catch are talking with.)
Standard date and time broadcast.
Media and other data telecommunications broadcast.
Off shore oil production communications. (between drilling rigs.)

In the upper HF band there still is…….
Police and emergency communications.
Off shore oil production communications.
Pipe line control and other industry related communications.

There is one MAJOR problem that they are ignoring.

The thing that people refer to as “skip” or “propagation”

BPL will not only cause interference to the listeners located close to the line. It will increase the noise floor on the HF band across the united states. One BPL stations may not increase the noise floor much a hounded miles away. But when you get a whole fleet of them, then the noise adds together.

And BPL takes advantage of the current method the FCC uses to measure emissions. FCC measurements are based on a point source. As you travel away from the point source, the noise energy drops at the square of distance. With a line source like a power line, the amount of energy emitted at each point along the line is small, but as you gain distance from the line, then the receiver starts to pick up a little bit of signal from all the little parts of the line, which add up to a big signal. So the actual amount of signal radiated is quite large when you look at the system as a whole.

To get at what I am talking about, keep in mind that some of the BPL transmitters are rated at 10’s to 100’s of watts. All that energy is radiated to the sky through leakage. Just not in one place.

When you are close up, the energy radiated from the line right next to you, dominates the signal. But when you are at a distance, then you still see all the energy from the entire line. So for a person in another state that is getting interference from the BPL. He will get the same signal strength from a 100W BPL transmitter feeding a 50 mile long line, as he will from a 100 watt transmitter feeding a 80 foot long half wave dipole. The former meats part 15 specs. The latter doesn’t by a long shot. But they both cause the same amount of interference.

So, BPL is an interference problem with ship to ship and ship to shore, and all other international communications. The only problem is the people being interfered with will have no idea where the interference is coming from.
