NTCA show arrives in Las Vegas, vendors push capacity solutions

Tipped by JSRoman See Profile
Cable industry bandwidth capacity and DOCSIS 3.0 are going to be hot topics this week as the the National Cable and Telecommunications Association (NCTA) show hits Las Vegas. Comcast CEO Brian Roberts will demonstrate 100Mbps DOCSIS 3.0. Expect even more discussion of bandwidth-saving technologies such as switched digital video (SDV), digital simulcast and spectrum overlay.

DOCSIS 3.0 vendors are pushing their wares in force; Motorola, StarHub and Vyyo are announcing that their DOCSIS solution has achieved lab and field speeds of 145Mbps using spectrum overlay:
"Testing took place over the StarHub hybrid fiber-coax (HFC) network, using Motorola network products and Vyyo UltraBand(TM) Spectrum Overlay solutions. Vyyo's Spectrum Overlay solutions use spectrum up to approximately 3 GHz frequency for increased upstream and downstream bandwidth, allowing MSOs to achieve competitive bandwidth speeds when used in combination with DOCSIS 3.0 network equipment.
The NCTA show website is here. As mentioned last week, Comcast will begin DOCSIS 3.0 trials this year, with more serious deployment in 2008.

A few years...likely to areas Comcast faces stiff competition first, everyone else later. Wonder if we'll be seeing the weekly Comcast is redlining news that we saw/see with FiOS.

Well Comcast has been confident that they will start rollout this year to certain areas (I am guessing areas with FIOS) and then having a very good portion of their network done in 2008...wasn't it 60% or something they were talking about?

Re: Let me know...

if they say 60% they probably really mean only 30% or 40% as most deployments there are usually hurdles and other things along the way that could affect it.

Re: Day Late and Dollar Short

Wow, and how many FiOS subs are there out of the millions upon millions of BB customers?

FiOS isn't a cure-all for anything, especially for those outside Verizon's service area.

All this FiOS fanboyism reminds me of the pre-capped OOL days when everyone was comparing everything to OOL..."Well my OOL is 10Mb, uR teh suk". Sure, great if you can get OOL.

Great if you can get FiOS.

Yea, and I won't mention about the caps that OOL started implementing either. Thats besides the point though.

I agree with what you are saying. I predict that a vast majority of comcast customers will be on 3.0 before FIOS is deployed nationally. Mainly because of the cost.

no it doesn't. Fiber will eventually be necessary but that is a long ways away. HFC networks are more than capable of handling bandwidth needs for at least the next 10 years, probably longer.

Only thing docsis 3.0 is going to do is enable providers to load even more subs on a node.

If they can up speeds; does lack of FTTH matter?

If they can achieve the same result of vastly increased speeds without running fiber directly to each home, does anyone care? And if they can get these speeds at lower cost, Wall St and customers should both be happy.

Re: If they can up speeds; does lack of FTTH matter?

It matters in only a lack of wireline competition. Other than that no. DOCSIS 3 will bring the needed bandwidth to expand services.

This can be a blow to justification to Fiber. Comcast will be able to do all the fiber has promised but with copper. Not to mention I live in a area with large apartment and condo complexes, the one FIOS keeps skipping. I see FIOS as the modern day OK Soda* , both are great products doom by lousy planning and expensive execution of the business plan.

Will this disable people from using 1.0 and 2.0 DOCSIS?

It will be backwards compatible, but you won't get above 1.0 speeds unless you buy a new modem.

Re: Disable?

Thats not true here with optimum online as long as you have atleast the 5120 or that webstar modem you can get 30/2 speeds wich are docsis 2.0 these modems are what cablevision has been giving out for atleast the past year or too to everybody.

We are talking about Comcast's network though. Comcast has said they aren't deploying 2.0 at all and I do know the modems are backwards compatible.

when comcast has introduced higher speeds when has it ever been accompanied by a new higher priced package?

Comcast HSI rates have not changed in years and there is no reason to think that will change now.

over subscriptions

that's the thing that worries me. I'm sure Comcast will be harder than ever on bandwidth hogs as their backbone gets bogged down by all these new high bandwidth users...

They put these higher speeds in competitive markets first, and they don't kick people off in competitive markets because they will just go to the competitor.

I dont see why peple think more Bandwidth means more heavy downloading? Downloaders will download no matter what, it just takes them longer, were not going to get a new bread of downloaders roll in or anything just because of the increase of Bandwidth. More will get used though because of all the HD stuff now and other features coming out which our ISP are selling and expect the need for the increase to handle it.
Our whole family are heavy online gamers, we watch HD shows and have never been told we use to much Bandwidth so I have nothing to sweat, the people that do reach "the cap" should get out of the house once in awhile. We use the Internet alot here so it's hard to imagin hitting "The cap" being I was told by my ISP I have nothing to worry about.

Because the people likely to want more bandwidth are downloaders. As you pointed out, most us actually have plenty of bandwidth for our needs.

IF their network is anything like cabevisions their backbone shouldnt have any problems because the backbone should be all fiber.

DOCSIS 3.0

Wireless network can also achieve the same speeds. But PR always avoids mentioning total throughput for the system. If there are 100 subs, what will be total throughput: 14.5Gbps? With increased amount of video streaming, they cannot hope that oversubscribing always work.

No sorry...

That 145mbit is shared between all users on the 'node' per say. This means 145mbit for anywhere from 30-300 users (normally).

Currently it's 38mbit with Docsis 1/2. So sure it is a little bit of an increase.

But when you compare Fios @ 622mbit per 32 customers - it's no comparision at all. (soon to be be 2.4Gbit for up to 64).

If you think no way the numbers I quoted above are possible: you don't know jack about the ISP business and overselling - my "local" ISP used to fit 100 768kbps DSL customers on one 1.5mbit frame relay T1. With traffic shaping on the router speeds during peak times might slow down to perhaps 384kbps - still not too bad.

Thats an oversell ratio of 50:1 (50mbit sold for 1mbit actual backbone). It happens more often then you think!

Re: No sorry...

They are bounding several channels to get 145Mbps per sub. And because they have increased frequency to 3Ghz, I expect total throughput to be 1Gbps+ , but it depends on Motorola hardware. That is why it is interesting to know from the source.

forget the technology for a second..

there is NO rush by the companies to raise the speed caps just yet... they are more interested in getting the technology in place "just incase" their competitors jump before they do..
raised speed caps are inevitable but not necessarily the TOP priority at current prices. just as $4 gasoline doesn't phase or even shock people anymore so will higher cable/telcom bills be the norm (just at a much slower rate increase than gasoline) and THAT'S when consumers will say, Hey, what's in it for ME?
higher price~better speed will go hand-in-hand. by the time 100/100 megabits rolls around consumers will probably be paying around $100 just for internet due to inflation. 1996-2004 (when it was promised) versus 2008-2016 which is more the reality for cable companies and telco companies to be capable of delivering said service... (the reality)

Until the beta test pissing contest goes into full scale deployments, it's all just smelly urine.
