Comcast DOCSIS 3 Expands

Comcast today officially launched and expanded its DOCSIS 3.0 service in a bid to compete against Verizon's FIOS and other very high-speed Internet connections. Originally available in a limited form just in the Minneapolis/St. Paul area, the now established Extreme 50 plan bonds cable channels together to reach downstream speeds of 50Mbps, or bandwidth three times faster than the provider's DOCSIS 2.0-era 16Mbps tier. The performance is high enough to make HD video feasible: a full 6GB movie can download in as little as 16 minutes.

Upload speeds have also been increased to about 10Mbps and allows for faster peer-to-peer gaming and other services where the user's network has to send large volumes of data to other users.

Monthly rates have dropped only slightly to $140 for the plan, which should now be available over the next few weeks in parts of New England area, including Boston, Philadelphia, and parts of New Hampshire and New Jersey.

In addition to expanding access to the 50Mbps service, the company is also adding an Ultra tier at $63 per month that boosts speeds in DOCSIS 3.0 areas to 22Mbps for downloads and 5Mbps for uploads. Users of the existing Performance and Performance Plus levels in those areas will also get automatic boosts to 12/2Mbps and 16/2Mbps respectively.

The shift comes as part of a larger strategy to eventually introduce DOCSIS 3.0 to all of Comcast's subscribers and has repeatedly been described as peaking as high as 160Mbps as the cable firm implements the full specification. However, these areas aren't described as having a bandwidth cap higher than the existing 250GB per month and should still be subject to the company's new priority throttling service, which temporarily slows down users in areas with excessive traffic by making data packets from very frequent users a secondary priority on the network.

    What's the flippin' point, if they're gonna throttle torrents.. Why would a home user need higher thruput unless they were torrenting? It's not like Apple's gonna give you 25 Mbps for patch downloads...

    Impact to TV?

    If I understand this correctly, they aren't increasing the bandwidth of the cable itself, but just bonding multiple channels together. So to make room for all this extra internet bandwidth, how much further is my TV picture quality going to be degraded?

    Quick Test

    Well, uploads are still slow, two tests from Vermont to NY and then LA about 1.5 and 1.7 Mbps respectively.
    Downloads, same locations, 12 Mbps and 10 Mbps, respectively.

    The download is a marked improvement. I'd still switch to FiOS if the option was here though.

    Bandwidth Caps???

    Don't they still have a 250GB bandwidth cap? At those speeds, you can use up your allocation for the month in under 12 hours.

    So they'll give you speed then take it away if you actually use it....
