It's a new system, they wanted to offer TV service, so they ran FTTH.

Unlike Fios - Comcast has to upgrade networks, get rid of analog, and do some other changes to get closer to what Fios can offer. These changes take time and plenty of money.

Comcast around here isn't too horribly oversubscribed, so PowerBoost actually means something, but the highest internet tier is 8/2 Mbps for pretty darned expensive, especially considering the 250GB cap that's gonna turn on the day after tomorrow.

Problem: there's little to no competition. Qwest's fastest DSL package is 5/896 nominal, 4.25/700 actual, and that's on a perfect day. Usually speeds are a good bit under that...the DSLAM isn't fiber-fed so we're stuck with capacity issues at peak times. First-hop latency is 45-50ms if you're not doing anything with the connection, much more if you are.

If TW wasn't going to cap their service I'd say I'd rather be with them in a heartbeat. For about what I'm paying now, back home I could get a 15/2 connection. Verizon, Embarq or even Windstream DSL would also be nice; I'm not even talking about FiOS here and we're looking at faster speeds than Qwest offers...with reference to Verizon I'm talking about their new 7 Mbps DSL tier.

DSLExtreme anyone? AT&T DSL (not even talking about UVerse)?

Cable-wise, I dunno. Armstrong Zoom? Grande Communications? Insight? WOW? I want sustained speed, not PowerBust.

There is a WiSP around here but I think a 5 Mbit connection is $60 per month, though that's better than $47/mo for Qwest for a connection that isn't even that fast. Not sure why "cheap" DSL starts at $40/month for dry-line service...and that only pays for 1.5 Mbps down!

So yes, competition would be good. But there are also much better companies to have as your monopoly\duopoly. Heck, it'd be awesome to have the old WOW DSDN back. Ah well...]]> http://www.dslreports.com/forum/remark,21187568 Mon, 29 Sep 2008 16:37:56 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,21187396 funchords : bsoft,

Comcast's competition here is Qwest, which doesn't offer TV service. Qwest offers ADSL2+ in a very, very few areas - otherwise, it's 7Mbps with 32ms of interleave-induced latency, and that's if your lucky. And don't even think about signing up without home phone service, because you'll pay through the nose.

So, with zero TV competition and very little Internet competition, Comcast doesn't have a whole lot of incentive to upgrade their network. We still have 65+ analog cable channels, we still have around 15 HD channels, and we still have crappy oversubscribed DOCSIS 1.1 Internet.

We have a perfectly good 850MHz cable system here. There's room for 150 full-bandwidth MPEG2 HD channels (even without SDV), plus 250 SD channels, plus 300Mbps of DOCSIS 3.0 goodness. The technology exists, right here, right now. Hell, most of it was developed right down the street at CableLabs (it's around 5 miles away).

But, you know what? I think that Comcast is a company that hates investing in infrastructure and technology. We still have the same crappy Moto cable boxes with the same crappy i-guide DVR. We still have tons of analog channels wasting bandwidth. And we still have crappy slow Internet. Comcast talks about deploying new technologies. Sometimes they do demonstrations. Sometimes they even deploy in a few markets.

But, at the end of the day, I've still got my TiVo HD with two S-cards (because they don't have M-cards in this area). I still have my crappy Thompson DCM425 cable modem that periodically loses sync because of line problems that Comcast won't fix. I still have crappy latency because my node is oversubscribed.

And, yet, I put up with all this crap because the alternative is 3Mbps DSL for $56/mo with Qwest. I guess that's the point. Here, there's no alternative. Here, it's Comcast or nothing.]]> http://www.dslreports.com/forum/remark,21185069 Mon, 29 Sep 2008 06:24:23 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,21177052 PGHammer : Dayum....Chesterfield?

Many of us work on these issues everyday, as mentioned DOCSIS uses 6.4MHz channel widths.

On upstream it can yes, not downstream. Downstream DOCSIS comes in 6MHz and 8MHz flavours.

The RF carrier downstream is the same on DOCSIS 3 as with previous versions, yes it is marginally wider due to raised cosine shaping but the 'wanted' bandwidth of the signal is exactly the same as with previous versions, same symbol rates, same modulations. It is in no way the cause of any incompatibility.

Unsure why you'd be seeing issues due to downstream changes, maybe some incompatibility between certain modems and certain CMTS but that really should not happen on a fully compliant DOCSIS 3 CMTS and DOCSIS CPE.

There are no RF differences between D2 and D3. The differences are in the MAC layer and the ability to bond the channels which are, in D2, discrete.]]> http://www.dslreports.com/forum/remark,21160802 Wed, 24 Sep 2008 12:18:34 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,21150427 Chaldo : So I live in Detroit Market..

I think that your usage of the term "frequency range" in reference to this is what is confusing..

There is no such thing as 6.13MHz w.r.t. DOCSIS

DOCSIS 3.0 uses the same 6 MHz DS [downstream] channels as legacy modems use. There are some differences. In DOCSIS 3.0 the channel can be PC (Primary Channel) [supporting legacy devices] only, Bonding Capable only or be MUXed providing service for legacy DOCSIS 1.x/2.0 devices as well as DOCSIS 3.0 bonding capable CPE devices. A DOCSIS 3.0 modem must use at least one PC channel for L2 protocol messaging.

On the upstream for channel bonding, DOCSIS 3.0 uses the same strategy as the DS. It takes multiple standard DOCSIS US (usually 3.2MHz or 2.56 Msym/s up to 6.4MHz or 5.12 Msym/s) and MUXes them together. Again, legacy devices can use any one of these and bonding modems can use one or up to four (limited to current HW limitations).

If you want to read the meat of the specification it is available at www.cablemodem.com]]> http://www.dslreports.com/forum/remark,21142409 Sat, 20 Sep 2008 16:44:28 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,21139297 EG :

If you read my two posts you would know what I was talking about I made it pretty clear.

I never said nationally regionally or globally.

I'm fully aware of the backwards interoperability of the docsis platform and the CMTS. That's not the problem, the problem has been getting the modems to use the slightly larger channel. There's still a legacy carrier in place for the one that don't work but that will be 2.0 and something they will try and whittle down to get everyone to the 3.0 do we can reclaim the legacy carrier.]]> http://www.dslreports.com/forum/remark,21138527 Fri, 19 Sep 2008 17:47:24 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,21137122 kpatz : I had an hour-long outage roughly midnight the other night (I only knew because my firewall box logged a DHCP renew to a 192.168 IP, and then a later renewal got my regular IP back).

DOCSIS 1.x/2.0 modems will register on a D3.0 CMTS but they will only lock on to their respective spec. Most downstreams are modulated at 256QAM which gives you about 38mbps of useable bandwidth.

The frequency range that D3.0 uses is the same as DOCSIS 1.x/2.0.

They push a firmware update to the modem that can accept the 3.0 standard for anything under 50mb. We also have a legacy carrier for modems that can't accept the firmware push, be it customer owned or just old CPE we haven't replaced. Docsis 2.0 specification is up to 43mb if I remember right so the modems are more then capable of handling up to that. The only reason why the modems don't work is because the 3.0 has a freq range of 6.123 mhz or something along those lines per channel.

speedtests say 40-44mb, and uplink is roughly 2-4....not sure why it is so low, when it's advertised as 50/5.

Anything I can check to clear this all up?

I am a DOCSIS 3 subscriber on Comcast in a suburb in the Minneapolis & Saint Paul (MSP) area of Minnesota. I ordered the DOCSIS 3 service the day it was announced. I use it heavily and test it almost every day to the Comcast speed-test sever as well as to www.speedtest.net and I reliably see my 5 Mb uplink. I see 44 Mb of the downlink due to the limitations of the workstation that I use for the test. The ping-time to www.speedest.net is consistently 65 mS +/- 2 mS.

I use the connectivity for professional purposes as I often need to transfer very large files. It is a splendid tool.

So is Comcast using full D3 yet? I read awhile ago that Cablelabs now has a full D3 modem out and with Comcast's phone feature in it. (for hookup)

It's a bit misleading. There are modems and eMTAs that are DOCSIS 3 certified, but...

DOCSIS 3 certification for modems are all or nothing, they're NOT tiered certs.

DOCSIS 3 certification for CMTSs are tiered in 3 different grades: Bronze, Silver, and Full; for cost and timeline reasons. A couple CMTSs do have full certification, but they're from Casa Systems which is a small maker not known for providing Comcast major equipment orders. Cisco, Arris, and Motorola each have a CMTS with bronze DOCSIS 3 certification, which means they're not certified for upstream bonding yet, and Comcast is publicly known to use CMTSs from each of them.

Here's the DOCSIS certified equipment list from CableLabs:
»www.cablemodem.com/downloads/Cer···ucts.pdf

On the other hand there is PRE-cert gear available to Comcast (at the very least for testing) which may have most of the features including upstream bonding working. The gear doesn't have to be certified by CableLabs for a company to use it... especially if the part or feature holding up further certification is non-essential for the level of service needed by the company using it. ]]> http://www.dslreports.com/forum/remark,20761562 Tue, 08 Jul 2008 22:08:46 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,20761070 espaeth :

I wonder however even without all the server tweaks wouldn't you still be able to get to that bandwidth by say downloading from multiple sources of higher bandwidth providers?

Yeah, that works just fine -- it's why I was initially sure that it was per-flow balancing across the channels. If I fired up one session it would hit 2.2MB/sec and never get higher, but I could open up another that would hit 2.2MB/sec, and a 3rd that would hit 1.8-2.2MB/sec.

So for now this would seem more marketing hype rather than actual throughput speeds. At least until more servers are tweaked. So rather than paying for 50mbps down speeds you're really paying for "Up To" in this case. At least the Upstream is much better.

I wonder however even without all the server tweaks wouldn't you still be able to get to that bandwidth by say downloading from multiple sources of higher bandwidth providers? Example: Downloading a very large file from Microsoft and at the same time pulling some Nix distro, etc. Perhaps the combined downloads would be able to hit the 50mbps mark as long as the sources can push at higher levels.

After all I see the problem as not so much how fast Comcast can provide it's more of how fast the data can be sent that seems more of the limitation for now!]]> http://www.dslreports.com/forum/remark,20680374 Sun, 22 Jun 2008 10:03:37 EDT Re: Yet another DOCSIS 3.0 install http://www.dslreports.com/forum/remark,20680265 espaeth : Update
Now that I've had a few days to test, I've been able to determine that my upper limit of 18mbps is purely coincidental based on standard TCP window scaling parameters and the fact that every remote device I can use for testing is > 18ms away. I went back and read the DOCSIS3 spec regarding their bonding solution, and they address out of order delivery by having massive buffering capabilities in the modem, which re-orders packets in the correct sequence before dumping them out the Ethernet interface. I spent a bit of time playing around with TCP tuning parameters on one of my boxes I colo @ Gigenet in Chicago, and I've been able to get transfers to hit 50mbps in a single TCP flow.

Server kernel version:

Server apache version:

Server TCP modifications:

wget result: (TCP windows didn't grow to hit 6MB/sec until 50MB into the transfer)

To get a better net result, I created a larger test file. After 50MB into the transfer speeds stayed consistently between 5.5MB/s and 6.2MB/sec.

Conclusion: Amended
So, the 50/5 service really is 50mbps afterall. It just looks like the it takes a lot of work to get TCP to perform at that level. Given the amount of tweaking I had to do to the TCP stack on my Linux box to achieve these results, I can pretty much guarantee that 95+% of Internet servers are not going to be tweaked to provide this level of performance.

Note: these tweaks need to be performed at the SERVER side of the connection; changes on the client side alone will be ineffective at bringing these results!

The most critical components are enabling Appropriate Byte Counting (with aggressive 2*MSS window scaling) to allow the window to scale based on the number of bytes acknowledged with each TCP ACK instead of just based on the number of TCP ACKs, increasing the TCP write memory space for outbound windowing, and changing the TCP Congestion Control Algorithm from 'bic' or 'reno' to 'cubic'.]]> http://www.dslreports.com/forum/remark,20680265 Sun, 22 Jun 2008 09:20:24 EDT Re: Yet another DOCSIS 3.0 install http://www.dslreports.com/forum/remark,20665227 EG : That is very interesting info espaeth.

(hope that works!)

Ordering

I first signed up for the service the day it was available, and then the following day after I found out upload speeds on the 8/768k plan were bumped up to 8/2 I called to cancel. I wasn't that thrilled about the required professional install ($39.95?) and was still a little uncertain if I really wanted it bad enough to justify the $149.95 price tag.

Last week I finally broke down and decided to go forward with the order again. I called and spoke with a sales rep who said that all I needed to do was stop by the office and pick up the modem and they would provision everything for me there. The Comcast office is about a half mile from my house and is right on my drive home, so stopping there was no problem at all.

Unfortunately once I got to the office, they told me that they aren't handing out the 2505s and that a professional install would need to be scheduled. The rep said that as long as I was there she would schedule the appointment for me, but she had to call for support because she didn't know how to code the order.*

Install

My install window was 3-5pm yesterday, but the first tech showed up a little early at around 2:45pm. The tech asked where I wanted the modem installed so I showed him my setup in the basement; he gave me a puzzled look for a few seconds because apparently his work order just said "Install HSI service" (* might be related to how the order was coded). He said he wasn't sure why a tech was dispatched for a modem swap, and that he would call his supervisor to confirm a few things. After he got off the phone he said that he couldn't do the install and that a commercial tech needed to be sent out.

About 20 minutes later the commercial tech arrived with the modem and proceeded to compete the swap. This ended up taking longer than I expected, only because for some reason the system wouldn't let him swap my owned SB5100 with the 2505 from his phone/PDA app that he was using for provisioning. A quick call to the office so they could manually change the assigned modem and things were up and running.

The service

The Scientific Altanta 2505 modem provided has 3 lights to indicate lock on each of the downstream channels, and a single upstream light. For those who care, the bootup sequence is a lock on DS1, followed by a lock on US, then DS2 & DS3 lock and ONLINE lights up.

I've only been able to do a little bit of testing, but the results aren't quite what I expected. It appears that the 50/5 service (provisioned as 55mbps/5.5mbps) is actually 3x18.33mbps/5.5mbps. This is important because it appears that the configuration is setup for per-flow load balancing across the channels instead of per-packet. This is likely configured this way to prevent out-of-order TCP packets between the channels. Since each DOCSIS channel is still shared infrastructure, it's possible that heavy traffic on one channel could delay delivery of packets more than the other two. In a best case scenario this would slow the rate at which your computer will increase the TCP window size and keep your transfers artificially capped for speed; in a worst case scenario your box will interpret the out-of-sequence packets as dropped packets and your transfer rates will turn to utter garbage. The net effect of this configuration is that each TCP session will be limited to about 18.33mbps downstream.

With my SB5100 on the 8/2 tier with Powerboost I would hit 3MB/sec downloading a 100MB test file from a box I have colo'd at Gigenet in Chicago, and after 30-40MB it would drop down to 1.0MB/sec. With the 2505 my transfer starts out at 2.2-2.3MB/sec and ends at 2.2-2.3MB/sec. So Powerboost was actually faster for each transfer initially, but the DOCSIS3.0 transfer still wins out because it's dead consistent at 2.2-2.3MB/sec for the entire transfer.

Most speedtest sites use multiple TCP connections (which would be balanced across the channels, since it's per-flow balancing) to test throughput, so Speedtest.net and others report numbers that are right on the money for the service:

Others have reported that the Minneapolis market was going to test a 25mbps connection, but based on what I'm seeing on the 50/5 service that was likely postponed because it would have resulted in 3 x 8.33mbps channels, or 2 x 12.5mbps channels.

Q: Do you get a unique IP address with the 50/5 service?

I didn't. In fact, I got the exact same IP as I had with my SB5100 once I got hooked up with the 2505.

Q: Are there usage limits on the 50/5 service?
I don't use my connection enough that I'll probably ever find out, but according to this guy, yes: »Review of Comcast by apok86

Conclusion

As much as I can have a conclusion about the service after just over 24 hours, overall I'd have to say I'm pleased with the results. The 5mbps upstream speeds are absolutely magical; uploading files to one of my web servers was remarkably quick last night. One thing I did notice, however, is that my overall latency went up about 2-3ms with the new modem; my server in Chicago always had a consistent 17-18ms round trip time, now it's consistently 19-21ms.

That's my $0.02 for now -- I'll post more information as I have it.

1. DOCSIS 3 doesn't specify a max number of bonded channels that can be used, just a minimum number (4) needed to qualify to be DOCSIS 3. That doesn't mean the provider has to use 4 to launch DOCSIS 3 though, they can use 2 if they want to.

This also means cable providers can output 32 DOCSIS downstream channels (or more) for the modems to tune to and bond if they wanted to. So if a modem is released that can tune to 32 channels at once it can use all 32 channels. An 8 tuner modem would have 4 bonded channel groups they can be configured to choose from or 4 tuner modems have 8 bonded channels groups to choose from or DOCSIS 2 modems have 32 different downstream channels available. Whatever combination it takes to use those 32 channels.

2. With firmware upgrades and hardware reconfiguration, the edge QAM modulators that are used to create VOD and SDV channels now can also be used for DOCSIS downstream channels. This means the same digital RF modulators can provide video, data, and voice services and can be reconfigured on demand. If a provider needs more SDV streams to meet demand, it can feed MPEG-TS streams carried over ethernet into the modulator for the cable boxes to tune to. If they need more data capacity they route the data packets into the modulator.

Now imagine what is possible when a provider installs the edge modulators needed to broadcast 100 channels of switchable video or data to replace their current single-purpose gear needed for digital/VOD/DOCSIS channel spectrum... that's where DOCSIS 3 is heading.

What are you trying to say? HFC means Hybrid Fiber Coax, so your saying most of the Hybrid Fiber Coax in Comcast is from the Ped on the Street to the House. Well that's all coax, and the fiber is brought to a node. The node converts that fiber to RF over coax, and it passes 250 - 1600 homes depending on system architecture, age, investment, etc...

I've scanned the spectrum. SECV was pushing to 123 at one point, but backed it down to 120. They've been replacing tons of feeder and pushing fiber further though. Theyve made one hell of an improvement. They used to only run 64QAM for video, noisy as hell, but now they are pushing 38-40 dB SNR at all 256 QAM. Cable Services LLC. has been around balancing the system after some upgrades, and now they are offering phone.

But in our system, there's not much space for Docsis 3.0. I'd say they should eliminate some analog and roll with the SDV. Both cheaper (and quicker) alternatives than rebuilding plant to 1 GHz.

As I see it, there's 12 MHz of bandwidth currently available (EIA CH 87, 88). They are pushing to EIA 118, ok 2 carriers post 750 MHz, no problems. To get bandwidth for Docsis 3.0 they are going to have to go SDV, reclaim analogs, and/or band edge test and see if they can push a QAM to EIA CH 120 or so.

You'll most likley see MSOs move toward utilizing advanced modulation profiles like 64QAM with a 6.4mhz width (which gives about ~30mbs of bandwidth.)

Updating a router with a new config file and updating billing isn't hard.

There is more to implementing 3.0 than just "updating a *modem* with a new config file".

Hardware must be replaced. ]]> http://www.dslreports.com/forum/remark,20547904 Tue, 27 May 2008 18:47:58 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,20544908 fndelta : As far as i am am concerned, just because DOCSIS 3.0 is being rolled out it doesn't require everyone to upgrade. TO me this sounds like a perfect oppertunity for comcast and other Cable COs to truly give the end user what he/she want. If you are just going to email and maybe look at cnn, give them 1.5 or 3 or some other low speed and charge then dirt cheep for it... then for those that want DOCSIS 3 speed, do relatively the same. If a company can cater to the individual, Which is possible. Updating a router with a new config file and updating billing isn't hard. then the consumer will be far more happy. Just a thought.]]> http://www.dslreports.com/forum/remark,20544908 Tue, 27 May 2008 09:43:01 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,20541091 Cjaiceman : Chiyo and I are the type of consumer that is never satisfied with what we have, we would always like more. If/When we get the 100mb service, we will be in the same boat again stating why we can't have 500mb service, or gigabit service. I would always love to have faster speeds, there is no such thing as "too fast", it just simply does not exist. I also just think that the US ISP companies are too greedy and will not roll anything out until competition does. That's the only driving factor for faster speeds. Those of us in low to non competition areas are hopelessly lost. Denver is a great example, we don't even have blast yet, while most of the country does. I actually upgraded to a business account because I got tired of waiting for blast. The other thing about rolling faster speeds is that the ISP's will have a larger area to cover, which does cost more than in an area like japan...

Ok, sorry to hijack the thread, back to DOCSIS 3.0 discussions :D

"A lot of people will need to upgrade their 100mbps ethernet cards/routers if any ISP starts dishing out 100mbps+ service. I don't know why any consumer would need faster than LAN speeds."

I'm sick of that excuse why the hell can't I have 100mb plus whats so wrong with me as a consumer having that much speed. Your logic is flawed and the last time I checked prices on gigabit nic cards were not that expensive.

if something came along that was faster I would take it because I'm a heavy user, I remote into work I podcast I use flickr I game all kinds of things if something will make my internet experience better then I want it.

People making that argument often argue from the viewpoint because they don't have the option to have it for themselves, or can't justify paying for it; but rarely is it for lack of desire should it be offered.]]> http://www.dslreports.com/forum/remark,20540822 Mon, 26 May 2008 11:19:25 EDT Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please http://www.dslreports.com/forum/remark,20539600 Chiyo : "A lot of people will need to upgrade their 100mbps ethernet cards/routers if any ISP starts dishing out 100mbps+ service.

Actually DOCSIS 3.0 can go 304Mbits/sec if they do DOCSIS 3.0 8 channel, Comcast is deploying DOCSIS 3.0 4 channel, but it might be easily upgradable in a few years once DOCSIS 3.0 is more established.

Agreed ... but as deployed is implied. That will likely [but not certainly] require new hardware on the consumer end and it isn't likely that Comcast is going to give up another 4 channels until they have switched from the standard TV model of delivery where all channels are delivered simultaneously to having content delivered on demand [i.e. switch TV or IPTV, etc]. For our discussion, I felt it safe to say that 160Mbps was the max that can be deployed [per Comcast] with their current technology.

My reply is simply to clarify what is otherwise a debate of semantics.

First...Qwest and their plans. Actually, I think they have the right idea and AT&T should follow what they're doing.
Qwest is not trying to be all things to all people. They're rolling out some fiber to allow them to better utilize their copper network and deliver very competitive hsi speeds.
AT&T on the other hand is doing the same with uverse except they're then trying to shove everything including the kitchen sink down those pipes. A uverse pipe at 25Mb would make a helluva HSI tier that is able to compete and compare with both cable and verizon fios today and for the next generation service. Instead..they're trying to get in the tv business which is causing everything they're offering to be viewed negatively by many a critic. Today, they've managed to rake in a whopping 300k + customers for the service after all this time. Can anyone say "total flop?". Because that's what it is.

Verizon Fios...If your plans are to be in the tv business and compete on triple play with the cable co's..verizon had the only right solution. It's a real next generation service..something that people look forward to...and so far they've managed to sign up a decent amount of subscribers.
What Fios also is though, is expensive as he** for Verizon to roll out. 25 to maybe 30 Billion dollars at last count.
There is a real risk in what they're doing. First..it takes a lot of time to wire their service area with door to door fiber. I think manhattan is projected to be finished in what..2011 to 2012 or so?
Verizon has GOT to add a lot of subs and really crank up the rollout if they're going to be able to keep their prices in line with cables offerings. A couple million customers is not going to foot a 25 Billion dollar network expansion.
I think the risk for Verizon is that a) the rollout drags on longer than expected. Imagine rewiring skyscrapers and the kinds of buildings major cities have. What a wall fishing nightmare that is. and b)..they simply have to raise costs higher than cable's triple plays to justify their ambitious expansion plans. And satisfy shareholders.

Verizon kind of reminds me of the rambus memory vs. DDR war.
Rambus..was better. Faster. But more expensive. They even had the backing of Intel. But who won? DDR did.
Because of price..and availability...and compatibility.
They made it to the finish line ahead of rambus..satisfied what consumers wanted..and did it in mass quantities.

IMO..Docsis 3.0 is just like DDR was at the start.
Perhaps a slight underdog in terms of comparing it to fios..but the potential is really there to move this out very quickly..take over the market..and quite simply..never look back.

IMHO..what Comcast and the other cable co's need to do..and MUST do..is get this rolled out fast..and price it aggressively. Make it a part of the top tier triple play bundles where the 16Mb tier now resides. They need to recreate what broadband speeds are in this country in the minds of consumers..and make it affordable.

Personally, while it's pure speculation...i'd say that is exactly what Comcast is going to do. I don't think they're investing in this across the country to make it a small niche product. Is my speculation right?

We'll see. But I do know that two of my greatest passions are following technology..and business.

And combining the two..I think Comcast has a huge winner on their hands and can deliver a knockout blow to the telco industry.

Docsis 3.0.

Bring it on. :)

DOCSIS 3.0 is only capable of 160Mbps down. They have to come out with a new DOCSIS revision if they want to go faster than that.

Uverse needs to clear a lot more technical hurdles to really become a threat in terms of broadband competition.

FIOS is definitely a threat but there is still some life left in cable yet. DOCSIS 3.0 could provide speeds in excess of 300mb/s in the future. In terms of capping bandwidth usage I agree that it will certainly discourage some customers from choosing Comcast. But I don't think that is going to be a major selling point except to an extreme minority of users.
