'12-14 Months' From Faster Upstream DOCSIS 3.0
Motorola says most carriers far from upstream channel bonding...
by Karl Bode Monday 30-Mar-2009 tags: bandwidth · cable
Earlier DOCSIS cable networks can only support transmissions within a single downstream 6 MHz radio frequency (RF) channel, limiting maximum throughput to around 40Mbps (shared). DOCSIS 3.0 upgrades will allow tuning into multiple 6 MHz channels through channel bonding technology, offering shared downstream data rates of 160 Mbps or higher and upstream data rates of 120 Mbps. However, upstream channel bonding has been slow in coming, which is why you're seeing a lot of very topheavy tiers with early DOCSIS 3.0 deployments (like 50Mbps/5Mbps).

Interestingly, Arris says they've completed the first 160Mbps deployment of DOCSIS 3.0 in Japan, and the first deployment of upstream channel bonding (though they don't specify what upstream speeds they're offering). It sounds like Arris is just pushing for bragging rights -- an article by Light Reading quotes Motorola as saying they don't think most cable operators will be deploying faster upstream DOCSIS 3.0 for a year or more:

For now, Motorola still has no specific plans to shoot for Silver or Full Docsis 3.0 qualification, which brings upstream channel bonding into the mix. That's partly because the vendor doesn't believe most MSOs will be ready for that for another 12 to 14 months. . . "We do not feel that is a business-impacting hurdle," Wagoner says of Motorola's present emphasis on downstream channel bonding. "But the upstream is becoming increasingly important. We'll be ready as the market needs that upstream capacity."

Rouzbeh Yassini, considered by many to be the "godfather" of the DOCSIS cable specification, recently highlighted how upstream bandwidth was going to remain a sticky subject for cable operators for the foreseeable future.

Hurry Up, Cable!

I hope they move faster than this. I rely on competition from cable speed increases to get higher speeds with FiOS. A little birdie has told us that the basic tier for FiOS will be 25/25 (75/25 for top tier) by June/July. Sold at the same price, it is going to be difficult for cable to compete where consumers have a choice between the two services.

God what I wouldn't do for some real competition here. You can get Comcast (fastest in my area), get a slower DSL setup, or get a slower WISP service which can be pretty unreliable at times.

Re: Hurry Up, Cable!

Yes, it is wonderful. I've not always had this luxury. Comcast is great in my area, too. It was only recently (November 2008)when FiOS added a ton of new HD channels that I finally made the jump.

Bandwidth Crunch is Real?

I'm starting to believe that cable may be in a worse situation without DOCSIS 3.0 than I thought. Time Warner is having all kinds of SDV bandwidth issues in my area as they try to squeeze more HD channels in. I frequently change from a channel, change back only to have it tell me that channel is unavailable. 3 tech vists, 2 supervisor calls and I've been told they are simply out of bandwidth and are aware of the issue. I've also noticed my picture quality going downhill. TW has never had issues in this area and it's not especially densely populated.

I did find it comical when the tier-1 rep tried to blame it on the DTV delay however.

Does cable have plans to do that? I haven't heard anything along those lines, but I agree. That would what, drop their video bandwidth consumption to 25% of what it currently is?

Re: Bandwidth Crunch is Real?

Well, okay. I know they have been talking about it (one of your links is 10 years old) but I meant do they have any firm plans? Time Warner doesn't even have hybrid boxes (much less full-blown MPEG4) available.

Can they get away with using a dongle like DTV does for some of their boxes?

There are MPEG4 STBs, some have been showcased at CES.

Customer owned devices like TiVo are already MPEG4 capable.

Yes it's real. It's mainly the fault of the suits, who raked in the cash for many years, but never thought people would literally use the internet. Verizon's analysts, for-seen the big internet boom, and people using their internet connections more and more.

Cable's biggest problem to date, is their last mile runs. They refuse, to upgrade their outdated, coax hybrid plants. They'd rather squeeze out as much as they can, because in their eyes. What really is the point of spending all this capital, when only 1% uses it! (remember 1% are the evil bandwidth hogs, claimed by many different ISPs)

TimeWarner Cable here in NYC - has the HD problem, they've squeezed so many channels in, but its too flaky. Channels say unavailable, channel changing is fun too, because sometimes you get 'stuck' in a very wonderful loop.

Docsis 3.0 means nothing, if they dont upgrade their plants. TimeWarner Cable is still on Docsis 1.1 - From reading various sites, and from the own horses mouth, they have no plan or intention to upgrade to 3.0 anytime soon.

this should be good times, good times.

Re: Bandwidth Crunch is Real?

HFC isn't outdated. It's just a medium that isn't being used all that efficiently right now primarily due to analog channels.

Drop 30 analogs = 1Gbit/sec+ of DOCSIS data
Drop 30 analogs = At least 60 HDs. More with SDV & MPEG4

The lower end cable systems are typically, at least, 550MHZ of bandwidth. That's more than enough if you manage it correctly but it's going to require the death of analog cable, cheaper downstream prices for DOCSIS, and more interoperability between EDGE QAMs so a particular node group can utilize this massive amount of bandwidth for the specific services/channels they are demanding.

lol 10/10 no way .. completely unnecessary.

10/2 would be fine for 99% of users.

Perhaps a 20/5 for top.

I use my 50/20 tier all the time. I hope they do upgrade us to 75/25. I will use that bandwidth on a regular basis. 20/5 is way too slow, and 10/2 would be unbearable.
I had 5mbs/1mbs speeds back in 1997. It was great then while most people were on dial up, but I need a much faster connection now since I'm using 1TB to 2TB of bandwidth each month.

Let's not start this again. Please?

The whole point is to offer faster tiers and let the market decide for itself what it needs. I, for one, would love the fastest tier possible. If my ISP could even provide those advertised speeds to begin with.

says who? a few years ago 3mbps/384kbps was fine for most users but now with the advent of 10 megapixel cameras, hd video, and video teleconferencing the more bandwidth available the better.

Then again I live in an area where I can get verizon fios AND 30mbps/5mbps optimum online cable.

Sure they are (i got my vendors mixed up elswere so sorry for that...), you do Know that "Casa Systems" and their C2200 CMTS are still the only DS3 vendor to actually get official Docsis3 gold/Full/final certification, as in all the bells, including Upstream Bonding certification as of right now , dont you ?

Arris (C4 CMTS), and Cisco (uBR 10012 CMTS) only have "Bronze", as in download bonding only ,NO official upstream Bonding CableLabs certifiaction to date

Re: Only "Casa Systems" have official upstream DS3Bonding today

To add to Pip's comment....Casa Systems has three CMTSs that have received FULL DOCSIS 3.0 qualification from CableLabs. The only CMTSs in the world to have passed the testing. Arris can make any claims that they want about the first FULL DOCSIS 3.0 network in the world...but that does not make it the first. The CASA C3200 CMTS has been deployed commercially in Sweden using both downstream and upstream channel bonding since December of 2008. Press releases don't make you first... "actions do".

72 and 288Mbps is not the maximum for FIOS. You need to read the tech specs on BPON and GPON again.

sliced and diced docsis-- meets reality check

Cable companies are NOT so enthusiastic about higher speeds because it undermines their Tiered TV packages and PPV-On Demand services. Who's going to buy PPV for $3-6 a pop when an few hours on bittorrent will net them the same content for the price of their broadband connection. Or, add in the cost of a broadband streaming service such as netflix/blockbuster.

It speaks volumes about what cable companies are willing to do-- cripple broadband by substantially changing the terms of service on the one hand... while price gouging the customer on the tv service and charging a premium for phone service (albeit cheaper than POTS, but amongst the highest average price in the VOIP industry). This lack of innovation and evolution of their business model (including expansion into wireless broadband) makes docsis 3.0 upgrades irrelevant for even more than 12-14 months.. try 60+ (5+ years) months or more!

While Verizon FIOS isn't an utopia of triple & quad play service provider... they at least had the foresight and courage to venture into true next generation networks-- without all the nonsense about being protectionist of commercial broadband customers and flegling cable-tv service.
