Bandwidth Crunch Looms for Cable Companies
coax4life writes "While Verizon and AT&T lay fiber, cable companies are looking at a huge bandwidth crunch according to a new report. Increased demand for high-def programming on the TV side and faster download speeds on the ISP side of the business will leave cable companies in a rough spot — after spending over $100 billion in the last decade on infrastructure improvements. Jumping on the fiber bandwagon may help. 'Upgrading to a fiber infrastructure is a much more expensive proposition, and one more likely to occur in areas where the cable companies are facing more competition. It can happen, though — several years ago, Comcast's predecessor on the northwest side of Chicago laid fiber on top of its existing coaxial installation. The payoff is good for both cable companies and users, as it can result in more programming choices and faster Internet access.' Moving to switched digital video solutions will also help."
That's what I pay you $60-$70 a month for. Don't complain to me. In the time I have had my cable internet service (since the first day it was available where I live)... Comcrud has raised rates, capped downloads, slowed speeds, raised rates, had dropouts, raised rates, etc. I really don't care that you are "overwhelmed". Maybe you shouldn't have sold 10k people 5 Mb connections when you only have a total of 500 Mbps of bandwidth. Maybe you shouldn't have lied.
Last week we got a letter in the mail that said that our streets would soon be torn up as AT&T would be replacing our terrible old copper with fiber to the home (our copper is bad, no DSL). We should be able to sign-up for their TV and internet service within about a year (so they say, I'd guess 1.5-2).
Of course, Comcrud has also dropped the quality of our cable TV, added next to no new channels, raised rates, and more. I would guess we'll switch off that too to U-Verse.
Comcrud is already in deep trouble in this area now that they will have actual competition. That alone will cause them big problems. But soon people won't be able to sign-up for their "ultra high speed" internet service so they can download music (which you have to pay for), download movies wicked fast (but you can't, and you probably have to pay for it), and surf at lightning speeds (if they aren't having a random outage)?
Why don't they do like many businesses, and stop selling services they can't provide.
Then again, I'm sure just about other /.er has the same sympathy I do for the lying US broadband industry.
Comment forecast: Bits of genius surrounded by a sea of mediocrity.
Ever since the whole bi-directional cable modem thing started, I've always hear it called the HFC network, hybrid fibre-coax. It's fibre up to a point, then goes to coax. I know that's the case here. The university I work for gets a cable feed, but it doesn't come in on coax. It comes in on fibre and is converted to coax on the premises (I've been to the cable termination room where it happens). They may need to build out their fibre networks further, but I think they've been doing that too. I know they've been segmenting the amount of users down further and further. A few years ago your segment was huge, you were in like a /22 subnet. Now it is a /26 and I don't see much traffic at all on mine.
Also I think the discontinuation of analogue will free up a good bit of bandwidth. I mean you have to remember that analogue takes up somewhere in the realm of 500-600MHz on most networks (a channel is 6MHz). Dump that for digital and you've got a whole bunch more available. Our cable network is 1GHz max bandwidth (since those are the splitters they provide) of that the lower portion is all analogue. In the digital portion they get all the analogue channels digitally broadcast (for their DVRs) several HDTV channels, 50 or so pay per view channels, and at least a hundred other digital only channels. More or less, they can do everything they do now in about half their available bandwidth if they axe analogue. That gives a whole lot more bandwidth for new stuff.
Amazingly there was only one intelligent thing said in the whole article. "Digital switching is key" is correct. Whats amazing is that some consulting has the balls to act like $great_prophet when proclaiming it. I mean, its not like Cablelabs hasn't been hard at work on the technologies to address the bandwidth issue. Both DOCSIS 3.0 (http://www.cablemodem.com/specifications/specific ations30.html) and Modular CMTS (http://www.cablemodem.com/specifications/m-cmts.h tml are designed to address this problem. M-CMTS basically works to divide cable plant into smaller sections by pushing the RF interfaces further out to the edge. This is done by placing fairly dumb/inexpensive edge QAM's out in the plant, these devices encapsulate DOCSIS frames into Gigabit Ethernet to carry them back to a packet processing engine. What this buys the operator is the ability to use fewer RF channels but gain more bandwidth at the cost of having some additional backhaul (to carry the GigE). Now some people might wonder if this consulting company is merely championing an idea that hasn't been developed, but sadly that isn't the case either. Many manufacturers are already producing EQAM's including big hitters like Cisco (http://www.cisco.com/en/US/products/hw/cable/ps22 09/products_implementation_design_guide_chapter091 86a00807c73c7.html/) These same EQAM's also handle switching of digital video so cable companies save on both switched video and normal IP traffic. DOCSIS 3.0 allows for bonding DOCSIS channels to create far more bandwidth, which is likely to be used for business services as well as more rich IP services. Comcast in my area already offers multiple HD on demand channels, for example HBO and Showtime. (http://www.comcast.com/HBOondemand/ and http://www.tvweek.com/news/2007/03/comcast_launche s_showtime_hdvo.php/)
Quite honestly it sounds like the "consultant" needs to do some research.
I believe that should be www.utopianet.org.
They were really, really ticked! Here's a snippet from Wired News, it's from late '04 when this whole thing was going down: (FTA @ Public Fiber Tough to Swallow):
If I mod you up, it doesn't necessarily mean I agree with what you've said, sorry.
