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 says “tens of millions” of homes already have the connections needed to support service with the technology with 300 Mbps, 500 Mbps, 1 Gbps, and 2 Gbps tiers. According to the Colorado Springs Gazette, the 300Mbps tier will cost $55 per month, including equipment rentals, and up to $115 per month on the 2 Gbps option.

After the Colorado Springs launch, Comcast will then bring X-Class service to Atlanta and Philadelphia by the end of the year and then to “new markets” nationwide over the next few years. Comcast will reach out to customers in the area where the new service will go live.
