Maybe by the end of the decade we'll all be rocking 1Gbps Internet connections. There seems to be an increased interest on the part of broadband Internet providers to keep pace with Google and its Google Fiber service, so it's not a matter of "if" but "when" we'll see gigabit speeds. If you're a Cox Communications customers, expect to see 1Gbps broadband Internet service available by the end of 2016.

Cox is planning to roll out gigabit service across all of its markets within the next couple of years, starting with Phoenix, Las Vegas, and Omaha.

"We are excited about our road map to offer gigabit speeds to all of our residential customers," said Cox Communications President Pat Esser. "Starting today, we will begin deploying new technology and infrastructure that will give customers the choice of gigabit speeds in all markets we serve."

As gigabit service is being rolled out to new areas, Cox said it will double the speeds on its most popular tiers from 25Mbps to 50Mbps. Meanwhile, Cox High Speed Internet Premier will jump from 50Mbps to 100Mbps. Between the two, they represent 70 percent of Cox's high-speed customers.
