Earthlink Invests In Broadband Over Power Lines

prostoalex writes "Earthlink dedicated $500,000 to delivering broadband connections over power lines by launching a test drive of the technology with Progress Energy in North Carolina. 500 homes involved in the projects can sign up for promotional pricing of $20/month, which after 3 months will be changed to $50/month. No word on bandwidth provided, but Ambient Corp., which provides technology for the project and accpeted EarthLink investment, claims data rates exceeding 10 Mpbs."

    claims data rates exceeding 10 Mpbs

    You know that you won't actually get 10Mbps for this, because the ISP's end bill and equipment needs would be to much. That's why all of the DSL/Cable companies have started sending acceptable usage warnings to their customers because they used up all of their unlimited bandwidth (God I love irony) (God I love being an agnostic who says God alot). Any who, as far as I know, this tech was meant more for giving broadband to them crazy country foke who ain't got them thar new digitized lines.... Right? Anyway, what is the range of these lines? How far away can you live from a "hub" or how exactly does that work....

    Pun intended. High winds or storms can knock out power lines, causing people to lose power, but if the ethernet connection is hooked up to said poles, we'll lose internet as well. Oh, whoa is me. Then again, I suppose that unless you keep a generator to run your computers in case of a power outage, it wouldn't really matter if the internet is not working while you're power is out. It's the principle that matters though!

    Like most regular slashdotters, I've seen this come up a few times, and every time it's mentioned that Broadband over Power Lines (BPL) interferes with all kinds of radios and devices, including ham radios and military communications. My question is this: does anybody think that the military will actually let this happen? Especially given our current state of paranoia, I just can't see the FCC overruling the armed forces and saying, "Nah! Change all of your communication gear so we can speed up Billy Bob Hick's internet!"

      Neither the FCC nor the Armed Forces make telecommunications policy in the way you infer. Both get their marching orders (pun intended) from Washington, and BPL has a lot of lobbying behind it.


      Please don't assume that the military will be able (or even inclined) to shout "Halt!" before the BPL onslaught: if they have to buy brand new radios to replace the single-channel paradigm they've been using for most non-critical traffic, then that's just another line item in a multi-billion dollar budget. That's what an industrialist would call a "Win, Win Situation", and any General officer would call a "battle not worth fighting".


      BTW, although the Armed Forces make heavy use of the spectrum between 30 and 70 MHz, their assignments are limited in the U.S. so as not to interfere with other users of that band: notably, TV channels 2, 3, and 4, and the public safety services others have mentioned.


      The 3 to 30 MHz (i.e., shortwave) bands haven't been used for primary communicaitons for years: satellite is prefered for over-the-horizon traffic, and even the lowliest dogface has access to email when in barracks, so the MARS system that used to carry phone calls in the shortwave spectrum isn't a big factor now.


      In other words, 3-70MHz is not the primary band used by the military in the U.S., so I don't think they've got a cock in this fight.

  4. Completely naive question... by dnaboy · · Score: 5, Interesting

    Not knowing much about how broadband really works, can someone explain to me why this wouldn't have the same limitations as DSL? So, with DSL there's a restriction on how far someone can be from a main telco box. Intuitively it would seem that broadband over power lines would hve the same issues, thus making it no more appealing to deliver broadband to the boonies than DSL, which the telcos have balked at due to cost.

    At least one thing will come of this. When the equipment begins blacking out HF spectrum, the furor should put this half-baked technology out to pasture once and for all. Imagine overseas flights using 10MHz HF SSB communications not able to get clearance to enter US airspace because their comms are blacked out by this garbage?

    If this gets to the point that it's deployed in my area, I plan to become *extremely* active on the HF Amateur Radio bands with *full* legal power. If it means fighting fire with fire, then by all means I'm prepared. They operate under the part 15 "non interference" rules. I operate under full FCC license to transmit. IOTW, I win. Hmm... when is the next DX contest???

    To quote Part 15: "must not interfere" means that they legally cannot interfere with my operation, and "must accept any interference" means that if I kill an entire neighborhood's internet feed, that's just the breaks. They cant stop my transmissions as long as I am complying with the rules and regs.

    But, being a realist, I suppose that once "big business" gets involved, then all they have to do is throw money, and they have plenty, at lobbyists and get congress to pressure the FCC to toss us hams off the air. Sadly, amateur radio does not have the status it once had.

    I know this is anal, but considering the lack of clear information about IP-over-powerlines, I will pose the following problem.

    I am a sound freak. I replace components in store-bought devices, I spend hours adjusting proper placement of speakers and matching cable lengths to millimeter precision. Now if some big ignorant comms corporation starts pumping multi-mhz modulation on my power lines, that will most likely affect my hi-fi components due to high frequency aliasing componded by cheap cabling and long distances. Wouldn't that be VERY BAD for these multi-thousand-dollar amplifiers that rely on crystal-clean power to do their thing ? Conventional power conditioners are designed for filtering minor surges and dips in power, as well as light induced noise (interference). Now if the company injects 'noise' on purpose, with higher amplitude and reflections accumulated over hundreds of miles.. methinks it will seriously hinder the transient performance of my gear and that of many other, more wealthy and lawsuit-happy people.

    I think this came from a Scott Adams (he was the telco industry and not yet the famous comic strip writer that we know and love) book, or maybe I heard it from somewhere else but it made sense: The challenge for telco's doing HighSpeed (DSL) was that they had mastered two-way personal communication but only at very low speeds. The phone system was designed for calls averaging only 3 minutes long. The cable companies knew how to deliver media, but only in one direction.

    My power company only delivers 3 things: high bills (like I will want to give them extra money), power and, my favorite, power spikes (I've gone through two coffee pots, 3 baby monitors and a dozen AC adapters for various things). Yes, the equipment is built by someone else but it will be installed and managed by people that are delivering the first and third things above. This does not have warm and fuzzy written all over it.

    We'll for some, a 3rd choice will be welcomed to drive rates down. For other's at least a single choice will be welcomed. More power to them.

    ARINC is a private company that provides radio communications for all overseas airline flights using radio frequencies impacted by BPL systems. ARINC has voiced strong opposition to the BPL, since based on their analysis, it will cause interference. Even weak radio signals can, by forming large antenna arrays over a power line grid, transmit signals over hundreds or thousands of miles. The US Federal Emergency Management agency also strong opposes BPL because FEMA also uses HF radio frequencies for disaster and emergency communications. The American Red Cross uses frequencies near 47 Mhz for coordinating disaster relief, and also has use of certain FEMA HF frequencies during disaster operations. The BPL industry itself has filed comments with the FCC acknowledging the problems with radio interference. However, the FCC is suffering from clouded thinking due to the Commissions desire to wish that their is a fairy tale solution to magically delivery broadband to more U.S. residences. And that by adding an additional technology to the mix of solutions, we will see greater competition and lower prices. The FCC, though, is itself very much aware of the interference problem but continues to hope for some magic technology solution. Numerous countries throughout the world have tested - and shutdown - BPL systems because of the widespread radio interference. BPL in the U.S. will - eventually - suffer the same fate. For now, the power line enthusiasts say they will merely not use radio spectrum shared with, for example, Amateur Radio. But that solution works for only one of the parties - by the time they fence off all of frequencies used by numerous bona fide HF spectrum users, there will be little left to provide useful BPL services.

    Ambient Corporation seems to be more about hype than products. Their main product is a "coupler" that allows passing RF around transformers. Those have been around for years, although the Ambient one is easier to install than the usual capacitors.

    Their new ideas revolve around ways to transmit data through underground power cables with multiple neutral wires. Big underground power cables are surrounded by multiple neutral wires, which has some shielding effect. The idea is to differentially drive those multiple neutral wires with RF. This is claimed to emit less external RF than driving the high voltage side of the line.

    In cities with underground cable vaults, it's easier to wire fibre or coax. Either provides more bandwidth. Ambient only claims 10Mb/s, and that's per cable segment, not per end user.
