Re: Dream Modem - 24x8

An article about the new ARRIS gateways also on the Multichannel News site today:

Looks like Netgear will be the first to release a 24x4 modem/gateway:

Netgear's 1-Gig Cable Gateway Breaks Through
By Jeff Baumgartner, Light Reading Cable - December 19, 2012
»www.lightreading.com/doc ··· lr_cable
Netgear Inc. is the first cable modem vendor to reveal that it has obtained CableLabs certification for a modem that can bond 24 channels and get within shouting distance of a shared 1Gbit/s downstream.

Netgear said it received the CableLabs stamp for the CG4500TM, a gateway with two voice ports, integrated Multimedia over Coax Alliance (MoCA) for wired home networking, and a dual-band 802.11n access point. The model's 24-channel downstream is paired with a four-channel upstream, the minimal upstream configuration allowed by the Docsis 3.0 specifications.

The device also uses MaxLinear Corp.'s MxL267 Full-Spectrum Capture tuner/front-end receiver.
:
A Netgear spokeswoman also confirmed that the CG4500TM is powered by the Intel Corp. Puma6 chipset, and that the product is expected to reach commercial availability in the first half of 2013.

Guess my 8x4 Moto will be fine for now - still waiting for that 24x8 though if I were to ever buy anything newer. Hell 32/16? :P

Since I doubt my ISP is doing anything soon, I think i'm good for now. Would still love a 100Mbps and say 20Mbps up even though my 50/8 doesn't slow me down now.

Very interesting. A modem with one of these chips would do Comcast's current fiber 305 service easily.

Think this would be what they need to bring it to the masses outside of the Metro-E area?

I don't think Comcast will ever offer 305Mbps service using DOCSIS 3.0. If they ever do offer such speeds over their HFC network, it would probably be by using equipment built to the new, currently-under-development DOCSIS 3.1 specs (see: »Re: Dream Modem - 24x8).

Also see Jeff Baumgartner's blog item today about all this:

Yeah, I did some reading on it and you're probably right. I do find it funny though. I just got the D3 upgrade here about 3 weeks ago, after 5 years of waiting. Docsis 3.1's first products aren't due until some time next year. Wonder how long it'll take to get me that upgrade?

Keep up the goodies. I'm drooling over here.

Except that would require upgrades to all of the cable nodes where they would provide this service via DOCSIS. It is easier going the FTTH route for these speed tiers.

Comcast announced its newest "Xfinity Wireless Gateway" which is capable of bonding up to 16 downstream channels, and incorporates a dual-band (2.4 GHz and 5.0 GHz) 802.11n wireless router which tests show can provide speeds of up to 270 Mbps:

Will this be any better then the ARRIS gateways we've heard horror stories about?

Personally, I just bought Asus RT-N66U. Whoever Comcast gets their gear from, I just want an EMTA version of this and call it a day.

Though, on the positive side, it lends evidence to the fact that Comcast will be rolling out a higher 205/xx speed soon.

Even if it's better quality, it will still have the inherent pitfalls that gateway devices have.. Just to name two of these pitfalls; like having more difficulties / complications when it comes to troubleshooting time (can't do process of elimination stuff as with separates), and also being a prisoner of the firmware updates that can come only from the ISP..

Yes. When you have an issue, it is better to be able to just modem + device = solution or still have the issue, proving it isn't whatever else you had hooked up.

Can't do that with a combo unit.

And ya know, I think I like being the one that says when my router is updated firmware wise and with what features disabled/enabled

Look at the recent Xbox issues with the ARRIS gateway. Hell, I think a friend of mine had the same problem for about a year with an 852G.

Don't know if Comcast uses any of their products yet, but a 24x8 gateway made by Hitron Technologies has achieved certification from CableLabs. The model CGN3 gateway's certification was revealed today when MaxLinear announced that the device uses its MxL267 Full-Spectrum Capture (FSC) digital cable front-end receiver: »www.businesswire.com/new ··· 2%80%99s

Are you guys sure the new gateway will be 16 downstream?

Actually, the MCN article cited only says that "the DOCSIS 3.0 modem chip in the gateway can bond up to 16 downstream channels" and I just assumed at that time that the unit therefore would be 16x4.

However, when examining all the Comcast press releases/blog posts/documents about it, I see they never mention how many downstream channels it can bond, only what the wireless speeds it is capable of.

As you've found, the Cisco's use of that chip in the DPC3939 only implements up to 8 channel bonding, and is only 8x4, as is the Technicolor TC8706C wireless gateway.

BTW - I also found these other Comcast webpages on the XFINITY Wireless Gateways:

This is good news, but it's also kinda sad they didn't test the full 24x8 cause they couldn't at the time. Are you tired of seeing Nx4 modems? Is this the point where we'll see Nx8 going forward?

As I said back in this thread »Re: 8 Downstream 8 Upstream Modems? , other than Comcast's HFC plant moving to a "mid-split" arrangement (extends the upstream path up to 85MHz), it doesn't seem likely that you'd be able to use an Nx8 modem with DOCSIS 3.0.

Well that blows, but still. At this moment, I'm more interested in my downloads getting to me faster then my uploads. Especially since you're seeing areas go 8x4 or better but still it's x4.

Man, I wish that they had a 24x8 modem out since things are changing around here soon and I'm gonna snag my own modem. Still, 8x4 is nothing to sneeze at, eh?

Thanks for the goodies. Hope you find more. I love drooling as I'll probably replace the soon to be bought 8x4 in about 3 years with whatever is newest at the time.

Damn, do I hate buying my own modem. This'll make my 8x4 look like it sucks. Still, when will systems have 32 channels to use? I guess I'll look at what's out when it's time to upgrade and go for the best I can get.

Unlike other areas, especially ones that have competition, my area takes years to catch up to everyone else.

By the time we could get 32 channels here, 3.1 will probably have been rolling out for 2 years.
