Earthlink Invests In Broadband Over Power Lines

Posted by timothy on from the keep-your-jacks-straight-please dept.

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."

    Once again the interference point has to be brought up, the company uses 5 - 70 Mhz, which dumps inteference out on the following bands:

    Several Amateur Radio bands (1.8, 3.5, 7.0, 10.0, 14.0, 18.068, 21.0, 24.9, 28.0, 50.0 Mhz)
    shortwave radio (7-14 Mhz)
    older cordless devices, such as phones (49 Mhz)
    CB Radio (29Mhz)
    Military communications (several)

    And there's probably more, but i'm too lazy to dig them up...

      That only implies direct interference, if you were to look at the even/odd harmonics for those frequencies then the "potential" for interference could be greater. I'm a geek and broadband kinda person, and enjoy my DSL. This might turn out to be a wonderful last mile solution, but the concern from a ham radio perspective is that if it does cause wide spread interference then there's the possiblity of impact to the emergency services provided by amateur radio. Just a thought from a "Ham"

      For those who think HAM operators have no foundation behind their objections to BPL please visit this site and see results of actual studies on interference.

      There is a lot of additional issues surrounding BPL. Such as the fact that power market is regulated and comunications market is not. Utility companies are going to finance their excursion into broadband internet access out of your pocket even if you are not going to use it.

    The article says that after the first 3 months the price will be $39.95, which is about $40/month rather than $50/month.

    I work for IDACOMM. We are CURRENTLY doing testing with both Ambient (to the plug) and Amperion (wifi) and let me just say....Ambient doesn't work. The technology is just way to infant. We were lied to by their sales, president, and engineering departments about how far along their "techology trials" in New York were. We currently have about 50 people deployed on Amperion, and it works a lot better. We are working towards "to the plug" techology, but we know that it is going to be for a lot harder than these articles claim.
