Discussing their earnings during last week's conference call, Time Warner Cable CEO Glenn Britt gave hints that the company maintains an interest in some flavor of wireless broadband, though not particularly wireless voice. "We haven't seen a big demand for the quadruple play to date," Britt told call attendees. "More interesting to me is the notion of broadband wireless," he said. Meanwhile rumors are circulating that Cox is preparing to build their own wireless CDMA and/or LTE network.Time Warner Cable and the other major cable operators recently scrapped their Pivot joint venture with Sprint, but it remains possible that some (or all) of them might jump on board to resell Sprint's Xohm Mobile WiMax service.
