AT&T has announced plans to bring Gigabit broadband connectivity to a further five new major metro areas by the end of the month. The latest deployments in Columbia (South Carolina), Jackson (Mississippi), Knoxville (Tennessee), Milwaukee (Wisconsin) and Shreveport (Louisiana) will increase the coverage of the operator’s fibre broadband access network to 51 major metros nationwide. According to AT&T, it has the largest fibre network across the 21 states where it offers a residential broadband service. The firm markets Gigabit connectivity to nearly four million customer locations, more than 650,000 of which are apartments and condominium units. Going forward, AT&T plans to reach at least 12.5 million locations across 67 metro areas with its 100% fibre network by mid-2019.
