The Network Evolution — DOCSIS 4.0, Symmetrical Speeds, and Invincible WiFi

Spectrum's multi-year Network Evolution initiative — upgrading the legacy hybrid fiber-coaxial (HFC) plant to DOCSIS 4.0 with Distributed Access Architecture, delivering symmetrical multi-gig speeds, and topping it off with the February 2026 launch of Invincible WiFi (WiFi 7 + 5G + 8-hour battery backup) — is how Charter plans to outlast the fiber overbuild threat. This module gives candidates the technical vocabulary and rollout context to sound credible on network strategy, especially for engineering, technician, and product roles.
