US regulators launched a broad assault on the US mobile phone industry on Thursday announcing an investigation into competition in the sector dominated by the ‘big four’ wireless network operators: AT&T, Verizon Wireless, Sprint Nextel and Deutsche Telekom’s T-Mobile USA unit.
The Federal Communications Commission, now controlled by the Democrats, voted 5-to-0 to pursue the inquiry, which is seen as a further indication that the Obama administration is stepping up scrutiny of antitrust matters.
