By some measures, the U.S. broadband market is healthy -- prices have fallen, speed has increased and millions of people have become customers in recent years. But customer choices are still limited, and prices could fall even more with more competition, one telecom expert said Friday.

Other countries with higher speeds and lower prices have generally taken a different route than the U.S., which has generally relied on the marketplace to determine the cost and quality of broadband, said John Windhausen, president of Telepoly, a telecom consulting firm. Japan, for example, has mandated that its incumbent telecom carriers roll out fiber-based broadband service, and many countries in Europe require incumbent broadband carriers to share their lines with multiple competitors.

In the U.S., most people have one or two choices for broadband carriers, cable or DSL (digital subscriber line) and fiber providers, he noted. "We don't have a sufficiently competitive broadband marketplace," he said during an Information Technology and Innovation Foundation (ITIF) forum on broadband competition.

The European line-sharing approach is modeled after the U.S. Telecommunications Act of 1996, but that approach was later abandoned by the U.S. Federal Communications Commission in favor of the network operator being the lone broadband provider. The Telecom Act has been "a huge success -- in France," Windhausen said.

In France, competitors of the incumbent network owner are now starting to build their own networks, using the profits they generated by providing service over the incumbent's lines, Windhausen said. That hasn't happened in the U.S., despite the FCC's efforts to encourage competitors to build their own networks, he said.

While Windhausen decried a lack of competition in the U.S., Jeff Eisenach, chairman of economic consulting group Empiris, called the lack of competition a myth. If people don't "separate out broadband," the U.S. telecom market is very competitive, he said.

The U.S. broadband policy "has unambiguously worked in terms of dramatic rises of [subscribers] and in terms of falling prices," Eisenach said.

Broadband providers are constantly improving service and speed, he added. In the Northeastern U.S., where Verizon and Comcast compete head to head, Comcast has begun rolling out service with speeds of up to 160Mbits per second, and Verizon is testing service of 100 Mbits per second, he said. Verizon's next-generation fiber service will be up to 400 Mbits per second, he added.
