Comcast is about to roll out gigabit-plus internet speeds for both upload and download without needing fiber upgrades that run all the way to the house. The company will offer a new “X-Class” service upgrade that supports up to 2 Gbps downloads and uploads starting in Colorado Springs, Colorado, next week. The city was one of the first places that Comcast launched its 2 Gbps internet service last year, although at that time, it still only supported 200Mbps uploads.
Comcast started testing symmetrical multi-gigabit DOCSIS 4.0 technology in 2022 using multiple cable modems and a 10-gig node (which is used for the Xfinity 10G brand name to highlight what’s theoretically possible, even if it’s not happening any time soon).
