Verizon To Use New Tech With Old Cables 188

Ant wrote to mention a ZDNet article about a new initive to get modern high-speed net access into homes utilizing old coaxial cable lines. Right now Verizon digs up streets and lays out expensive fiber to get homes online, but new tech may let them accomplish that task for much less hassle and expense. From the article: "Later this year, it plans to use new technology from the Multimedia over Coax Alliance (MoCA) , an industry group that promotes using coaxial cable installed for cable TV to transmit broadband around the home. The organization says that its technology supports speeds up to 270 megabits per second. Because most homes already have coaxial cable installed in several rooms, Verizon can significantly reduce its Fios installation costs by using existing cabling to connect home computers to its broadband service."

I have no idea about this MoCA scheme or the modulation of it, but my guess is that 270 megabits is going to be absolutely unattainable for most people.

          The few installations I've seen have used RG-6. Anyway, my guess is even with RG-59 they're using double- or quad-shielded cable in the studio. Cablecos and installers in general, on the other hand, can and do cut corners wherever possible, including using unshielded cable. Some years ago, I used to live about a block from a firehouse, and every time those guys hopped on the radio - which was quite regularly, obviously - channels 19-21 on the cable TV turned to complete shit.

      • Also most houses don't have the coax hardware to do this either. The distribution systems, if they are recent, have bi-directional splitters so that you can do things like buy pay-per-view movies, etc. But as far as I know they don't let the signal go down one cable and back up the other, which is what you need for this. At the least they'd have to install some new hardware where the splitters are currently- and sometimes the splitters aren't in easy-to-reach locations.

    Verizon came and fixed my voice line last week - we had a lot of noise and other people's phone calls on our line. Unfortunately this also 'fixed' my DSL connection, which hasn't worked since then. Perhaps by using a separate set of wires for voice and data this kind of problem will go away.

    I think its a great idea to use "existing" infrastructure to reduce costs and speed up implementation. IMHO a "new" technology using copper is suitable as long as it meets certain criteria (which I'm sure it does). My only beef with the article is in the title -- existing copper cables are not "OLD" technology -- copper has many advantages over fiber in terms of practicality, cost, etc. I'm going to consider that they were referring to "copper" as old... but I don't foresee and sudden disappearance of wires in the near future.

    • The standard is ancient. I don't know where it came form orignlly, but some time back in the eairly days of video, someone worked out that coax cable made a good waveguild for RF signals and they decided on 75 ohm coax to do it with.

      It works great for many things, no question. Provided the tolerances are tight, you can use it for uncompressed HD video (and the broadcast industry does) at distances around a kilometre. However that doesn't change the fact that it's a very old standard. Still extrememly useful

    I thought they learned the last time not to band-aid these issues. We have fiber that would be upgradeable to ??????? speeds, or we can bottleneck ourselves yet again at 270mbit (and that's probably theoretical only) so in reality maybe 200mbit? So that in another 5-10 years they'll have to do the fiber thing anyways. Why not just do it right the first time so there's a nice long-term upgrade path?
    • thought they learned the last time not to band-aid these issues.

      Well, a band-aid costs about $0.10, whereas surgery could easily run more than $10,000. Both have their place, and I'm sure Verizon has done the math to see which will be most profitable in the long run.
      • Yeah. They use the cable company's investment right now to save themselves some money, and by the time that capacity has been saturated, they'll be able to finish the upgrade correctly for a fraction of what it would cost right now, and will have already have gotten the money from gouging the customers.

      This shows what is possible today with coax. Production studios are shipping uncompressed digital HD over coax all the time (smpte 292m runs at 1.4Gbps), although they are often having to replace connectors and take more care in bending radius. 270Mbps shouldn't be a big deal if the cable is properly terminated and not kinked.

    I had Cat6 run from the Fiber terminal up to the computer room when I got FiOS installed. The Fiber will still go to the home but the connection will not be Cat6 according to this article. All it states is that instead of running Ethernet they will use the pre-existing Coax lines to make the connection. I plan on getting the Verizon Television (FiOS TV) and have already read that they will use my pre-existing Coax for that connection.

    So this article summary is misleading. The fiber is *still* going to the home, it's just that they will not run Ethernet into the home if they don't need to. Instead using the pre-existing Coaxial runs which are already in place.

    However, in cities like Montreal where houses are very old and almost impossible to run any new cabling, this has been an alternative for years. Without this technology, there would have been almost no broadband outside of cable modem in Montreal, much less the majority of the rest of Canada's old cities. However, as its said in the article, this is not primarily for an internet based usage. This is more related to the features of the new IP-based television services. Even in new houses today to find networking cable near a TV is a shot in the dark, and this technology, even though by no means new, will allow Verizon (and the other Telcos that are providing the same service) to install the services without having to ask the customer to change their entire room configurations around. Since the tech provides enough throughput to stream video, its a perfect solution for something that would otherwise cost a lot of money. The post is misleading though as this really has nothing to do with the wiring outside of the home. MoCA is not made for outside use, its an internal usage, with a host adapter acting as the router for the coaxial lines. Coaxial to ethernet bridge, thats all they are.

    It's just another ISP corporate "make money without spending it" hoax. You see these once every few years. A major telco/cable conglomerate/backbone operator/ect talks about using some old'n'busted tech to deliver a faster than pie in the sky internet connection. Almost all the initial information is from the marketting dept of the company that is selling the idea (not from engineers or anyone who could really explain how these fabulous data speeds will be accomplished).

    Stock Market laps it up like candy. Thinks Company X is going to become the new King of Content Delivery (because, you KNOW all the company's competitors and going to sit on their hands and have their kiesters handed to them by Company X).

    Then there will be delays of getting the project actually going. Maybe even some slight downplaying of actual speeds of conetnt delivery.

    At some point someone with a PhD in physics or a heavy EE background gets ahold of the actual method of content delivery and point out it simply isn't possible in the real world because of interfereance, older lines than they used in the lab, ect.

    Marketting dept for technology company downplays statement made by PhD/EE. Slashdot crowd made up of people who know WAY too much about the national power grid and enough about radio spectrum to work at the FCC pop up to defend the scientist's statements.

    More backpedaling of speeds for new service. Marketting direction of new tech starts to veer slightly into the "will allow service in areas not currently reachable by standard broadband providers" direction.

    Companies who have not yet publically committed to using tech start to back out. In the others unfortunately, corporate inertia takes over. Whoever greenlighted the project doesn't want to try and back out and look stupid for having wasted plenty of company money at this point.

    New tech has limited rollout, shows to be the flop we knew it was the whole time. You never hear about the new tech in the media again and it becomes one of those fringe technologes only seen in rural regions. Perhaps eventually phased out as traditional broadband service (Cable/DSL) are pushed into the region.

      Baseband signals, like classic coax Ethernet, are a pain, because they go all the way down to DC, which means you can't filter out hum from power lines. Ethernet only worked because it used strong signals on really good coax. It's not going to work over the crap cable TV uses.

    Smooth. Getting the damn fiber in the ground once and for all sounded like too good of a plan did it? Verizon needed a way to move back in time instead of forward? I wonder how many more years carriers will spend trying to squeeze whatever they can out of old, decaying infrastructure. We all know how great cable modems and DSL work compared to 'true' digital circuits (T1, Frame, etc) and fiber-based infrastructure. There are so many fundamental flaws with reusing old wiring for new services that I don't even know where to begin (Cable Modems = shared medium & collision city, DSL = distance limitations and interference, etc.). Because most homes already have coaxial cable installed in several rooms... GIVE ME A BREAK! I'm sure that was a real deal-breaker.

    I have FiOS service currently -- phone, internet, and TV -- and they are already putting IP over coax. They use it for the video on demand. They have a simple ethernet to coax bridge (made by Motorola) and the cable box then is able to get it's guide data and VOD streams over the internet connection. What I haven't been able to figure out is if the bandwidth used for VOD is taken out of my 15mbit internet bandwidth allocation or if they have some traffic shaping going on for the VOD separately.

    I'm not really sure how it's going to be cheaper -- coax isn't that expensive, and they were more than happy to replace the sub-par cabling that MediaOne/AT&T/Comcast had left behind. They even ran more wire inside the house to accommodate the way I wanted to setup things.

Also, the regular channels for video also do not come out of the 15/2 -- but, the VOD streams do. I can confirm this because I have a 10/100 switch hooked in between my router and the box bridging the ethernet and coax. When I play VOD streams, the activity lights are blinking like crazy. Pause the stream, and there is no activity.

As a result, the spam and zombie activity from their customers has dropped off dramatically. ISPs like Comcast and Verizon still have yet to do this and they're a major source of internet pollution.

    Until Verizon controls the illegal activity of their users, I urge all system administrators to block all port 25 traffic from Verizon IP blocks such as:

    Here's the funny thing: 270 Mbits over coax has been around since the early 1990's. It was called CCIR601, but then the ITU dissolved the CCIR so the standard is now known as ITU-R BT Rec.601 or some such alphabet soup. It was also called (inaccurately) "D1 video" (D1 is/was a digital video tape format). Since then, the 270 Mbit transport layer has been used for moving MPEG around, which is called DVB-ASI (that's right, as in the European "Digital Video Broadcasting"). ASI stands for Asychronous Serial Interface, and is the common transport for data between MPEG-2 encoders, IPE's, and MUX's at DTV head ends throughout the world. So, the idea that you could move lotsa stuff around at 270 MBits, even on crappy home-installed RG-6, is not rocket science. Making products that can do that CHEAPLY in the HOME is NEWS! (A DTV head end is a $million or 2.)
