Comcast today announced that its gigabit cable Internet service will be available in Atlanta and Nashville early this year, with the next deployments coming to Chicago, Detroit, and Miami in the second half of 2016. Exact deployment dates haven't been revealed.

Today's announcement also said that Comcast's fiber-based 2Gbps service, which launched last year, is now available to 18 million homes as planned. That's a sizable chunk of Comcast's network, which passes 55 million homes and businesses in 39 states and Washington, DC. The 2Gbps fiber service launched first in Atlanta, spreading next to Chicago, Detroit, Miami, Nashville, and other metro areas.

While Comcast's fiber-to-the-home service—known as Gigabit Pro—delivers 2Gbps both downstream and upstream, it won't be available throughout Comcast's territory. Comcast says it does plan to bring gigabit cable to "virtually" its entire territory over the next two or three years. That's due to version 3.1 of DOCSIS, the Data Over Cable Service Interface Specification, which can bring gigabit download speeds without the need to deploy fiber to homes. New modems will be required.
