Elon Musk's next target: A major shake-up of America's wireless market

SpaceX is assembling pieces to become a major U.S. wireless carrier, potentially building its own terrestrial network and buying spectrum, aiming to bypass or negotiate with existing carriers. Elon Musk's financial resources distinguish him from past challengers, but he faces daunting obstacles. Analysts suggest he may move quickly while current regulators remain, with some citing merger proposals between Tesla and SpaceX.
