Cellphone carriers that spent years promoting their blueprints for new fifth-generation wireless networks devoted the past week to explaining how they plan to pay for them. AT&T and Verizon said they would spend billions of dollars more in the coming years on cellular-tower equipment, fiber-optic lines, and other infrastructure to use new wireless spectrum licenses they acquired through a federal government auction. T-Mobile said it would put the new licenses to use without increasing its capital budget.

Congress is considering the most significant changes to antitrust law in decades, including some proposals with bipartisan support. Lawmakers are looking at setting a higher bar for acquisitions by companies that dominate their markets; making it easier for the government to challenge anti-competitive conduct; and potentially forcing some giant technology companies to separate different lines of their businesses.
