Re: Dream Modem - 24x8

The Comcast and fiber thing won't last. It was done as a marketing thing for now. The high install price and contract should have given that away.

99% of people can't qualify for it probably and COAX can handle much more bandwidth still. (currently is limited by the frequency range being used).

The future is all TV will go to IP and at that point the entire frequency range on COAX can be dedicated for Internet and when someone is not watching TV that idle bandwidth will be able to feed someone elses Internet or provide more bandwidth.

Works the same way hosting companies do now. They oversell because they know not 100% of customers use 100% resources.

Fiber to the home may be the future but in the US it seems most are not willing to make the change when they can keep pushing existing tech.

Phone companies will have the hard time, cable not as bad as they can do more channel bonding to gain the speed.

And to support these future "dream" modems, ARRIS will be showing off their new, CCAP-capable, model E6000 CMTS at this week's Cable-Tec Expo in Orlando:

Arris Unleashes a Monster CMTS
By Jeff Baumgartner, Light Reading Cable - October 15, 2012
»www.lightreading.com/document.as···lr_cable

From the article:
Arris says the decision to use the E6000 as a massively dense Docsis CMTS represents a "middle step" that addresses the near-term needs of cable operators as they continue to increase downstream capacities and bump the amount of bandwidth per subscriber by shrinking service groups.

Running the E6000 in CMTS mode will come in particularly handy when cable operators start to bond as many as 16 downstream channels, says Todd Kessler, the VP of product management for Arris's CMTS platform.

ARRIS will will be displaying their new Intel Puma 6 (»newsroom.intel.com/community/int···ble-show) based gateways at this week's Cable-Tec Expo.

From today's Light Reading Cable's cable news round-up (»www.lightreading.com/document.as···lr_cable ):
Arris Group Inc. is the latest cable modem vendor to introduce Docsis 3.0-based gateways that take advantage of the full capabilities of the Puma6, a chipset from Intel Corp. that can bond up to 24 downstream channels and produce speed bursts close to 1 Gbit/s. Arris's new line of gateways also will be outfitted with MaxLinear Corp. tuners and video-optimized Wi-Fi chips from Celeno Communications.

Arris's latest lineup, which will be on display at this week's Cable-Tec Expo in Orlando, includes two gateways that bond 24 downstreams and eight upstreams, and five models that use the Puma6's 16x4 configuration.

Other vendors are sure to follow with 24x8 D3 gear, but Hitron Technologies Inc. was the first to announce a model, and already has plans to submit its new gateway for CableLabs certification next month.

At the end of that article, it says:
And 3.1 is also about the almighty dollar as broadband usage continues to climb. Getting costs down "is a key part of Docsis 3.1," said Cox Communications Inc. EVP and CTO Kevin Hart.
And one way to do that is by providing higher (competitive) speeds without spending a lot of money doing FTTH:

Docsis 3.1 Will Change Cable's Data Channels
By Jeff Baumgartner, Light Reading Cable - October 16, 2012
»www.lightreading.com/document.as···lr_cable
Utilizing one of those [200MHz-wide] blocks would enable cable to produce a data path in the neighborhood of 1Gbit/s. Cable [companies could] later bond together 200MHz-wide channels together to create multi-gigabit capacities and give cable the ability to keep up with fiber-to-the-premises (FTTP) speeds without having to pull fiber all the way to the home.

Well, they did say things will move faster with DOCSIS 3.1 than with 3.0:

Docsis 3.1 Set for a Spring Fling
By Jeff Baumgartner, Light Reading Cable - October 29, 2012
»www.lightreading.com/document.as···lr_cable

From the article:
The first iteration of hardware specs for Docsis 3.1 could emerge as soon as next March or April to help cable modem and cable modem termination system (CMTS) vendors get a jump on product development for the new, speedier CableLabs platform, multiple industry sources tell Light Reading Cable.
:
According to the information presented by CableLabs at this month's Society of Cable Telecommunications Engineers (SCTE) Cable-Tec Expo in Orlando, the plan is to have the Docsis 3.1 specs "substantially complete in 2013," setting the stage for the first wave of Docsis 3.1 products to appear sometime in 2014.

This item »www.lightreading.com/blog.asp?bl···d=227176 on the Light Reading Cable site concisely lists the main areas in which DOCSIS 3.1 signaling will be significantly different from earlier versions:

•Using a higher order of modulation, for greater spectral efficiency, could conceivably add at least 25 percent more capacity and up to 50 percent more over the same HFC network. Note that the proposed DVB-C2 specification in Europe has been tested to support 4096 QAM downstream within existing cable networks.

•A new modulation format, Orthogonal Frequency-Division Multiplexing (OFDM), that takes efficiency and robustness to new levels. OFDM enables sub-carriers to be squeezed directly against one another, eliminating the need to use valuable RF spectrum as guard bands. At the same time, the longer symbol durations of the sub-carriers make OFDM more capable of dealing with impulse and burst noise than are SC-QAM guard bands.

•The use of Low Density [Parity] Check (LDPC) coding to improve noise immunity by several dB over current Reed-Solomon encoding at similar channel efficiency, or to provide greater channel efficiency at the same MER (modulation error ratio).

Some more CCAP news today:

Cisco Extends Bridge to CCAP
By Jeff Baumgartner, Light Reading Cable - December 12, 2012
»www.lightreading.com/document.as···lr_cable
On Wednesday, the company launched two capacity-boosting cards -- the Performance Routing Engine (PRE5) and the 3-Gigabit Shared Port Adapter (3GSPA) -- made to snap into its widely deployed flagship CMTS, the uBR10K. They'll act as an intermediate step toward CCAP, an architecture meant to help cable unify all services, including video, under IP.
:
Cisco says trials are planned with "several major" cable operators in the U.S. and abroad starting in the first quarter of 2013. Cisco didn't name them, but Comcast Corp. and Time Warner Cable Inc., two of Cisco's key customers, are expected to be among the first MSOs to test and deploy CCAP.

Comcast has already issued a CCAP request for proposal (RFP) and has said it will begin some initial deployments this year. More details about that could emerge today at noon E.T. during a Light Reading Cable webinar sponsored by Cisco that will feature John Mattson, Cisco's senior director of strategic marketing, and Jorge Salinger, Comcast's VP of access architecture.

Re: Dream Modem - 24x8

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/document.as···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.

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).

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.
