Analysis of next-generation cable technology promising 10 Gbps downloads and dramatically improved upload speeds.
DOCSIS 4.0: The Cable Internet Revolution
DOCSIS 4.0 promises to transform cable internet: 10 Gbps downstream, 6 Gbps upstream potential. First deployments beginning in 2024, widespread rollout expected 2025-2026.
Key improvement: Upload speeds increase 10x over DOCSIS 3.1. Current 35 Mbps uploads could reach 300+ Mbps, making cable competitive with fiber for remote work and content creation.
Comcast, Charter, Cox announcing trials. Existing coax infrastructure usable with node upgrades. More cost-effective than fiber deployment in established cable markets. Could extend cable competitiveness another decade.
