Comcast installs DOCSIS 3.1 Gigabit class modem on live network in Philadelphia

23 Dec 2015

Comcast, the largest broadband provider by subscribers in the United States, has announced what it claims is the installation of the world’s first live DOCSIS 3.1 modem on a customer-facing network. Having deployed the equipment in a property in Philadelphia late last month, the cableco said this represented ‘the next important step forward in delivering Gigabit speed broadband over [its] hybrid-fibre coaxial (HFC) network’. Notably, Comcast highlighted the fact that the test utilised the standard cable connections that it already has in homes across the country, coupled with a new modem and a software upgrade to the device that serves that neighbourhood.

On the back of the development Comcast has said it will continue testing over the coming months, with a view to delivering a commercial DOCSIS 3.1-powered service to customers in ‘several parts of the country’ before the end of 2016. To that end, the operator has already expanded the trials to additional locations in Pennsylvania, Northern California and Atlanta, while in the coming months it says it will activate a number of additional test homes in order to observe how the technology performs in multiple real-world environments.
