AT&T Begins Testing High-Speed Internet Over Power Lines (reuters.com)

AT&T has started trials to deliver high-speed internet over power lines. The company announced the news on Wednesday and said that trials have started in Georgia state and a non-U.S. location. Reuters reports: AT&T aims to eventually deliver speeds faster than the 1 gigabit per second consumers can currently get through fiber internet service using high-frequency airwaves that travel along power lines. While the Georgia trial is in a rural area, the service could potentially be deployed in suburbs and cities, the company said in a statement. AT&T said it had no timeline for commercial deployment and that it would look to expand trials as it develops the technology.

"We think this product is eventually one that could actually serve anywhere near a power line," said Marachel Knight, AT&T's senior vice president of wireless network architecture and design, in an interview. She added that AT&T chose an international trial location in part because the market opportunity extends beyond the United States.

Yeah, higher speed internet to more customers... call me cynical but sounds much like waiting for the flying car, controlled fusion power plants, men on Mars, etc.

      Regarding emergency communications, first order of business is emergency managers (and fire chiefs, IC, others) want to first be able to talk across their town, not to another county, state. Local comms can be VHF, UHF. Of course when everything goes down, there's no power in the power lines so no interference then can do HF.

      Maybe you don't realize that the reason people use HF to communicate out of a region that has lost long distance comms is because the RECEIVING END still has service and can send help? As in, all the RF interference from the RECEIVING END'S BPL will keep the receiving end of the emergency communications from being able to hear it.

      We have an HF radio in an EOC to serve the county Emergency Manager, but it has so much interference that it is absolutely useless. When the backup generators kick in to provide power for the HF radio, they'll also be powering the crap that is causing the interference. What a great system. Glad we have it.

      >The emergency communication issue is irrelevant because of mobile cell towers.

      Remember Puerto Rico? No power whatever - well, almost - everything was out except for extremely limited areas with emergency generators. The American Red Cross asked the American Radio Relay League (ARRL) for help. The ARRL is ham radio. The ARRL was able to send 22 operators that went down to Puerto Rico and relayed health and welfare messages back to the USA.

      Those messages came in chiefly on 7.000 - 7.300 megahertz bad, known as 40 meters. Broadband over Power Lines (BPL) of about 10 years ago would clobber the hell out of bands in this area of the spectrum. While there was no BPL or anything else in Puerto Rico to interfere, the USA hams on the other end would not be receiving these 40 meter signals with a power line going "Braaaaaappppp" in the backyard for the purpose of delivering internet signals over a power line.

      This is an idea that deserved to die before it was formed. Hopefully this will be shot dead with a bazooka before anyone can deploy it.

      They have done a minimal version of this for years.

      The problem is that this is another one of those ideas where people believe they can trump the laws of physics.

      The last time this was attempted, It failed pretty miserably. There are some serious problems. A power line is an antenna of sorts. You put signals on it, and they are going to radiate outwards from it. And the different frequencies of all the digital data will create a rather broadband hash. It interferes with licensed services. Attempts were made to notch out the frequencies that it used to not have the interference, but intermodulation, the mixing of different frequencies kind of made the notches not do much. The square-like waves of digital signals just make a splattery mess.

      Then there is getting it into the house. The concept uses the signals coming in on the house wiring But the signals don't survive goingthrough the transformer that feeds poer to your house. the cure such as it is, is some bypass circuitry that has the signal travelling down high tnesion lines. like a couple KiloVolt, then bypassing the transformer. to your house line. Hopefully the failure mode is always open.

      And the real kicker is that just about any radio transmission can knock them out. Kids with hand-talkies, People with CB radios, amateur radio operators, airplaines passing overhead.

      Coupled with the fact that it's a "Last Mile" solution, it needs an actual fiber or cable line to get the signal to the BPL lines, the main purpose of BPL is to extract investment money from people who do not understand RF.

      It's always sold as a way to get Internet access to people who aren't in a populated area. That part is 100 percent bogus. What would be the point of a last mile solution? They have to run the real line alomst to the house way out in the country.

  6. Ethernet over Power... by Anonymous Coward · · Score: 2, Informative

    As well as Power over Ethernet have been solved problems for at least 10-15 years.

    The title option is waveguided maser transmission of digital signals over powerline, essentially the same as cable TV only using power lines instead of coax. The issues with it include radiated energy from long distance power lines (which as a result of the length of the lines can act like HUGE miles spanning antennas), the inability to hop transformers (meaning you need hardware at every transformer in order to continue communicating over higher/lower voltage links, similiar to cable with its distribution boxes up on the telephone poles), and last but not least competing standards for the communication protocols, each of which can interfere with other units on the same line.

    By doing this they will require building out another cable-like medium plugged directly onto the high voltage lines, where failures could knock out some or all of the electric grid. EM interference which could cause degradation for HAM operators, wifi users, or microwave/satellite internet users, some of whom may have it as their only means of communication. And lastly: yet another proprietary standard locking people into equipment which is only suitable for the one purpose, interferes with alternatives and is being used to cover for the fact that AT&T got paid billions for a fiber rollout wherein they pocketed the money and then charged us all up the ass for shitty copper connections anyways, until verizon gave them the bright idea that if they pull their copper they can claim previous restrictions on them were tied to the copper and not to their status as a private communications company with monopoly status over multiple regions.
