Cox Communications announced a significant benchmark for its ongoing DOCSIS 3.1 deployment, touting 40% coverage across its footprint. 

The privately held operator said it will have 90% of its footprint covered with the 1-gig service by the end of 2019.

Cox, the third largest U.S. cable operator, made the announcement at the CES show in Las Vegas. 

"As one of the first providers of gigabit internet speeds, we are excited to rapidly expand that choice to more of our customers nationwide," said Cox CEO Pat Esser, who is attending CES in Las Vegas this week. "The innovative technology and devices displayed at CES are all powered by broadband, and our latest investments help bring these connected applications to the businesses and residents of the communities we serve."

Cox said it has spent $15 billion on infrastructure upgrades over the last 10 years and will spend another $10 billion over the next five years. It also noted that it is powering Wi-Fi at the Las Vegas Convention Center through its business/hospitality network division. Cox is providing 2,100 access points at CES, along with a redundant 10 gigabit backbone internet connection and a distributed antenna system equivalent to 14 cell towers.

In terms of DOCSIS 3.1 deployment among U.S. cable operators, Cox ranks behind Comcast, which has rolled out the technology to the majority of its footprint. No. 2 operator Charter, however, is just getting started.
