The Knoxville Utility Board (KUB) says it has completed the first phase of what will be the nation's largest municipal broadband deployment, bringing affordable fiber access to more than 50,000 premises in this city of 192,000 – many for the very first time. All told, the $702 million project aims to deliver affordable fiber to 210,000 households across KUB’s 688-square-mile service area, taking between seven and ten years to complete.
