CableLabs Introduces DOCSIS 4.0 — Up to 10/6 Gbps Over Cable Broadband

Phillip Dampier March 26, 2020 Broadband Speed, Consumer News 1 Comment

CableLabs unveiled the final DOCSIS 4.0 specification today, dramatically improving upload speeds and offering the potential of much faster internet service from cable operators in the next few years.

DOCSIS 4.0 will support downstream speeds as fast as 10,000 Mbps and upload speed as fast as 6,000 Mbps, finally bringing faster upstream speed to cable company-provided internet. The new standard raises maximum speeds by opening up “extended spectrum” on the coaxial cable coming into your home. By dedicating additional frequencies for data services, cable companies can raise both speed and capacity.

Consumers have been asking for faster upload speeds to support streaming live video, cloud backup services, and a growing number of in-home devices sharing a single internet connection. For years, cable providers have only been able to provide a small fraction of upstream speed in comparison to download speed. That distinction will largely be erased as DOCSIS 4.0 gets deployed over the next few years. Providers are likely to raise upload speeds on existing speed tiers and offer consumers symmetrical download and upload speed for gigabit connections. The increased speed will also likely make cable broadband more attractive to business customers.

The new standard will also decrease network latency, crucial for some online applications. It will also feature more robust security and higher reliability by identifying potential network problems before they become apparent to customers.

Consumers may see DOCSIS 4.0 modems and service available within the next two years.

Only useful if you have cable. 13 houses in 0.6 miles from where cable stops to my house. Comcast shows no interest in extending the cable.
