Homeowners in a City of Brotherly Love competence have even a faster proceed to upload and download calm from a Internet. On Dec. 22, Comcast announced that it would hurl out a new network that promises gigabit speeds — DOCSIS 3.1 — in a Philadelphia area.

In a statement, Comcast wrote that this could be a initial DOCSIS 3.1 network reaching residential customers. The association is still conducting tests, though it skeleton on bringing some-more residents onto a network by a finish of 2016.

Here’s how Comcast described a technology in a statement:

The next-generation record that will broach gigabit Internet speeds changed from a laboratory to a vital room late final month when we commissioned what we trust to be a world’s initial DOCSIS 3.1 modem on a customer-facing network. At a home in a Philadelphia area, we took a subsequent critical step brazen in delivering gigabit speed broadband over a hybrid fiber coaxial network.

In further to Philadelphia, Comcast skeleton to extend a services to other locations in Pennsylvania, Northern California, and Atlanta.

DOCSIS (Data Over Cable Service Interface Specification) is a customary that allows wire companies to broach Internet use over a same wire they use to broach television. The latest version, DOCSIS 3.1, is backward-compatible with existent networks. That means no digging adult streets or backyards to reinstate wire wiring.

No pricing for a use was announced.

This is some-more critical as a record exam than it is a proceed to assistance someone in Philadelphia work faster. Comcast is regulating a customary wire tie already in a customer’s house. There’s no need for additional wiring.

Comcast concurred this when it said, “All we indispensable was a new modem, a program ascent to a device that serves that neighborhood, and a few good engineers.”


If this exam works out, a implications are huge.

Comcast business will be means to get gigabit speeds with usually a new modem and a program ascent to a area placement hardware. The labor-intensive and costly cabling changes that competence have been differently indispensable don’t seem to be a factor.

Comcast had already formerly trumpeted that this arrange of thing was entrance in 2016. However, to have a operative and organic exam bed this shortly creates a company’s explain that is it deployable in a nearby destiny seem distant some-more realistic.

It also contrasts severely with a Comcast has formerly offering aloft Internet speeds. For example, in Atlanta it has betrothed 2Gbps (double what it already offers there), though with wiring changes for fiber required. Customers would also have to be located nearby a fiber nodes. It was not transparent how a DOCSIS proceed would contest with or element this 2Gbps service.

Google, naturally, is concerned in a foe to take fiber to new locations. The hunt hulk has announced enlargement plans, and a Google Fiber is already live in Kansas City; Provo, Utah; and Austin. The enlargement area will embody 18 cities opposite 4 new metro areas: Atlanta, Charlotte, Nashville, and Raleigh-Durham.

But Comcast has finished something truly opposite with a DOCSIS approach. The association has leveraged a existent network and delivered 1Gbps speed with minimal fuss. Comcast could be a initial ISP in homes with this approach, and so win a diversion before others get started.
