Cable company Cox Communications says it plans to boost Internet download speeds to 1 gigabit per second starting in Phoenix, Las Vegas, and Omaha, late this year. That is dozens of times faster than typical broadband plans. The move will bring its service in line with Google’s fiber rollout in cities such as Kansas City, Provo, and Austin; as well as an AT&T rollout in Austin. Cox also said it plans to add 1 Gbps Internet speed to any new residential construction project in its footprint nationwide in places such as San Diego, Providence, Orange County, Baton Rouge, and Tucson.
