US telecoms regulator the Federal Communications Commission (FCC) is to launch a probe into competition within the US mobile market.
The FCC wants to monitor competition information as the sector moves beyond mobile voice towards data services such as mobile broadband.
It will assess the power of networks such as Verizon Wireless, AT&T, Sprint Nextel and T-Mobile to assess whether lack of competition is damaging to consumers.
FCC chairman Julius Genachowski (pictured) said: “We are at a pivotal moment in the mobile industry; transitioning from a voice-centric world to one of ubiquitous mobile internet access.
“This transition promises to increase the pace of innovation and investment, but only if we have an open and competitive marketplace that gives every great idea a chance to make its way to consumers.”
