Comcast will make a $15 million investment to build and expand its high-speed, reliable network across Charlotte County, company officials announced. Thousands of homes and businesses in the areas of Rotunda West, Gulf Cove, South Gulf Cove, Port Charlotte and other neighborhoods will have access to Xfinity and Comcast Business services. Construction is ongoing, and services will become available as projects are completed. Company officials said some areas, such as Port Charlotte and Rotunda West, are now serviceable. The next-generation network gives the county access to internet speeds up to 1.2 gigabits per second for residential customers and up to 100 gbps for businesses.
