Time Warner Cable spokesman Justin Venech, on the other hand, said the following: "Mobile voice over the 4G network is something we are evaluating at this time...But we don't have formal launch plans in place in regards to a mobile voice product." While Venech didn't concede any commitment to mobile voice, it wouldn't surprise us if TWC were making a move for the mobile phone industry. They've been reselling Clearwire's WiMAX service, and using Sprint's EV-DO network for roaming. So it wouldn't be a big stretch to adapt a phone.
But a move into mobile phones would place them in the midst of a tumultuous mobile market, including AT&T's potential acquisition of T-Mobile, and the continuing struggle between AT&T and Verizon Wireless. But, as they would merely be adapting a device to use on Sprint's infrastructure, a failure wouldn't spell complete disaster.
And besides, TWC reports that their existing mobile efforts are producing "not very impressive and pretty inconclusive" results. So they are probably deciding between investing more heavily in their mobile efforts, or throwing in the towel.
