Comcast installs its first commercial modem with DOCSIS 3.1 technology for a customer in Philadelphia, providing speeds of up to 1 Gbps
Comcast now offering 1Gbps speeds across DOCSIS 3.1 — Comcast has connected the first commercial DOCSIS 3.1 service to a customer in Philadelphia, providing speeds of up to 1Gbps.
Context & Ripple Effects
This installation is the first working proof of a plan Comcast laid out in August, when it committed to upgrading its entire cable network to 10 Gbps-capable DOCSIS 3.1 within two to three years, starting with 1 Gbps tiers. Until now its fastest consumer offering was the 2 Gbps fiber-based service launched in Atlanta, which required new construction rather than the existing coax plant.
First-order effects
- A Philadelphia customer now receives up to 1 Gbps over standard cable infrastructure, turning Comcast's DOCSIS 3.1 upgrade from announced roadmap into delivered service.
Second-order effects
- Comcast can now market gigabit speeds across its footprint without per-home fiber builds, pressuring Google Fiber's premium positioning and cities weighing municipal broadband like Chattanooga, where Comcast lost its suit against public fiber and responded with faster tiers.
Third-order effects
- If DOCSIS 3.1 scales as planned, the speed race shifts from who has fiber to who upgrades software and silicon on existing hybrid-fiber-coax plants — extending cable's cost advantage over fiber overbuilders and slowing the case for municipal networks built purely on speed gaps.
The trend: Cable operators are using DOCSIS 3.1 to close the gap with fiber competitors on their existing networks rather than rebuilding them.
