The U.S. Federal Communications Commission (FCC) barred merger talks among telecommunications companies for over a year as it conducted a $19.8 billion auction of airwaves from broadcasters for wireless use.
Sprint was not in the auction but could not talk to companies that were. Now that the quiet period mandated by the FCC is over, it can have such discussions.
