AT&T, T-Mobile and Verizon form satellite venture to tackle U.S. cell dead zones

AT&T says it has entered a joint venture with T-Mobile and Verizon to expand satellite-enabled coverage where U.S. cell service is limited. The companies say it will complement existing networks and aim to nearly eliminate dead zones currently without mobile service. Existing carrier-satellite agreements can remain in place. Engadget reports there is no timeline yet for when the venture will offer coverage in dead zones.
