While the Federal Communications Commission's latest report on wireless competition in the United States shows that more Americans have access to multiple carrier options than ever before, it also shows that competition for services is still more highly concentrated than it was two years ago.

According to the report, 98% of Americans in 2006 had three or more carriers offering services in their counties, while nearly 94% had four or more carriers offering services in their counties. However, the number of Americans who had access to five or more carriers in their county in 2006 remained relatively low compared with recent years, with roughly 59% having five or more carriers offering service. The percentage of Americans who had access to five or more carriers in their counties stood at about 87% in 2004, before plummeting down to around 51% in 2005. Three major telecom mergers occurred between the start of 2004 and the end of 2005, including the Sprint-Nextel merger, the Verizon-MCI merger and the AT&T-Cingular merger.

But even with competition more highly concentrated, FCC chairman Kevin Martin said that he was pleased to see more Americans than ever had access to multiple carrier options in 2006. He also praised many carriers for voluntarily offering to give their customers open-access options to that would let them connect to their networks using any device of their choosing. These options, he said, would foster more competition and would further benefit consumers.

"As I noted when we adopted open network rules for the ongoing 700MHz spectrum auction, wireless customers should be able to use the device of their choice and download whatever software they want onto it," he said. "I continue to believe that more openness – at the network, device and application level – helps foster innovation and enhances consumers' freedom and choice in purchasing wireless service."

Commissioner Michael Copps said that the FCC's latest wireless competition report was more helpful than past reports but he was still concerned about how well the FCC defines "effective competition" in its reports, which he said, "leaves consumers, industry, and Congress with no clear idea of how this Commission will react to further changes in the market."
