Comcast will begin rolling out DOCSIS 4.0 to select neighborhoods in Colorado Springs next week and to areas of Atlanta and Philadelphia before the end of the year.
Comcast’s path to DOCSIS 4.0 leverages “Full Duplex” technology which uses the same network spectrum to increase upstream speeds without sacrificing downstream speeds.
Symmetrical 10 Gbps service based on fiber-to-the-home technology is already available in all of Comcast’s markets, and as part of its continued network evolution and the introduction of DOCSIS 4.0, multi-gig symmetrical speeds are rolling out.
New and existing residential customers connected via DOCSIS 4.0 will have access to Comcast’s newly introduced next-generation X-Class Internet portfolio. X-Class speed tiers include X-300 Mbps, X-500 Mbps, X-1 Gbps and X-2 Gbps upload and download speeds and low lag for the ultimate live sports streaming experience on Peacock, smooth connections on work calls, and ultra-responsive gaming.
“The ubiquity of our network, which is already accessible to tens of millions of homes, provides us with an incredible opportunity to bring multi-gigabit upload and download speeds to communities across the country with the scale and efficiency that no other provider can replicate,” said Dave Watson, President & CEO, Comcast Cable. “Our connectivity experience, powered by the Xfinity 10G Network, will allow us to deliver speeds up to 10 Gbps over our traditional network to virtually all our customers, plus even better reliability, lower latency, and the best in-home WiFi coverage. We’re entering the next phase of this industry leadership with DOCSIS 4.0 technology to introduce X-Class Internet products that will revolutionize the way our customers get online today and many years into the future.”
“The enhancements that we have been making to our network over the past few years have been foundational to creating an award-winning network architecture that is fully virtualized and capable of delivering these exciting capabilities to our customers,” said Elad Nafshi, Chief Network Officer, Comcast Cable. “This is an awesome achievement and I’m incredibly proud of the team of brilliant technologists here at Comcast who have worked relentlessly to make DOCSIS 4.0 a reality ahead of schedule.”
- In April 2021, Comcast conducted the first-ever live test of full duplex DOCSIS and later that year tested the world’s first 10G connection all the way from the network to a modem.
- In 2022, Comcast conducted a world-first live trial and connected a business location in the Philadelphia region to its live network including a DOCSIS 4.0-enabled 10G node and multiple cable modems.
- In February 2023, the company marked another major milestone in the nation’s largest and fastest multi-gig deployment by announcing its latest Xfinity 10G Network upgrade launched to 10 million homes and businesses.
