Comcast has not announced pricing for its “Gigabit Pro” service, but the MSO continues to expand the number of markets that will gain access to it.

Comcast said the service, which will deliver symmetrical speeds of 2 Gbps over fiber to residential customers, will soon be available to about 650,000 homes in parts of Indiana (Indianapolis, Anderson, Bloomington, Fort Wayne, Columbus, Kokomo and Lafayette), and to roughly 1.5 million homes in several cities in Michigan, including Detroit, Grand Rapids, Flint, Jackson and Lansing.

Comcast has also announced it will offer Gigabit Pro in Atlanta; parts of Florida, including Miami and Jacksonville; Houston; Colorado (including metro Denver, Fort Collins, Loveland, Longmont and Colorado Springs); Utah; Washington State (including Seattle, Spokane, Tacoma, and Everett); Oregon; Chicago and northwest Indiana; Minneapolis/St. Paul; Chattanooga and Knoxville, Tenn., and parts of California.

The MSO’s plan is to make Gigabit Pro available to 18 million customers (homes that are within about one-third of its fiber network) by the end of 2015.

Pricing on the service is expected to emerge when Comcast begins to market Gigabit Pro sometime this month. A Web page promoting the service, originally spotted by DSL Reports, temporarily indicated that the service would start at $299 per month, but Comcast said pricing, including introductory and promotional rates for Gigabit Pro, were still being considered.

Comcast also plans to offer gigabit speeds via its its more broadly deployed HFC network using DOCSIS 3.1.
