Our sister publication FierceCable reported that Cox Communications is beginning to use the Wi-Fi roaming deal it struck last year with fellow cable operators Comcast, Time Warner Cable and Cablevision to market premium tiers for its high-speed Internet service. Cox subscribers who sign up for its Preferred, Premiere or Ultimate broadband service will be able to surf the Web from the nearly 150,000 hotspots that are part of the CableWiFi consortium. Cox subscribers who log in through CableWiFi hotspots in markets such as Boston, Philadelphia, San Francisco and Washington, D.C., will be able to automatically access the hotspots for 180 days, the company said.
