Czech Republic Broadband Wireless Network Model Competing Well with DSL with No Interference Problems 7/30/08 - For the past year, Deutsche Telekom's T-Mobile unit and AT&T, two of the largest phone companies in the world, have claimed that the FCC's proposal to require a free nationwide wireless broadband service that competes with DSL will not work because the service will cause interference to their operations in adjacent spectrum bands.
In the filings that T-Mobile made at the FCC today and on July 18th, T-Mobile asserts that broadband operations in the 2155-2180 MHz spectrum band designated by the FCC for its free "lifeline" service should not be permitted because tests conducted by its engineers demonstrate that those operations will cause interference. These filings, however, fail to mention that T-Mobile itself is currently providing broadband services that compete with DSL in the Czech Republic using similar spectrum and similar technical rules to those that the FCC plans to adopt for the free broadband service. According to information from the Czech Telecommunications Office that is in direct contrast to T-Mobile's claim here in the U.S., T-Mobile's broadband service is operating with well-established standard power limits and without having to use spectrum guard bands. To date, T-Mobile has not provided this ostensibly material information to the FCC. Instead, T-Mobile has repeatedly argued that time division duplex ("TDD") technology would be disruptive if deployed in the U.S. adjacent to its frequency division duplex ("FDD") operations in AWS-1 due to mobile-to-mobile interference. In the Czech Republic, however, T-Mobile's broadband wireless deployment uses TDD technology in an unpaired spectrum band that is adjacent to a paired ("FDD") operations without special protections or limits to guard against mobile-to-mobile interference. These claims of interference that T-Mobile, AT&T and other wireless carriers are making at the FCC have been soundly rejected by international regulators including the United Kingdom's spectrum regulator OfCom, as well as the European Commission. The links below demonstrate T-Mobile's regulatory doublespeak by showing that its Czech wireless broadband service has been successfully implemented and has, in fact, been expanded to operate on more than 600 base stations that cover 60% of the Czech population since it was first rolled out 2 years ago.
"I am greatly disappointed by T-Mobile, AT&T, and other phone companies continued opposition to all Americans having access to free wireless broadband services," said John Muleta, CEO of Silicon Valley-based M2Z Networks. "These multi-billion dollar companies have the resources to affordably connect Americans to the opportunities of broadband but instead waste the country's time by using their significant lobbying resources to gum up the FCC processes and stifle innovative new services and competition. As a former FCC official, I'm also particularly troubled by T-Mobile's selective presentation of information at the FCC about the state of the art in wireless technology and interference management." Despite the significant public support for the FCC's lifeline broadband proposal, T-Mobile and AT&T consistently have opposed the deployment of a free nationwide wireless broadband network. The ongoing attempts of these companies to thwart the availability of affordable broadband in the U.S. using unfounded claims of harmful interference will exacerbate America's global competitiveness by continuing to keep poor, minority, and rural Americans from having affordable access to broadband. Currently, 71 percent of Latinos, 70 percent of low-income households, 69 percent of Americans living in rural areas, and 60 percent of African Americans are disconnected from the opportunities of broadband Internet. "M2Z has long called for the opportunity to provide a free and family-friendly broadband service throughout the United States," said Milo Medin, M2Z's Chairman. "The Commission's plan to auction the long fallow 2155-2175 MHz band for a lifeline broadband service will kick start broadband competition, lower prices, and provide all Americans equal access to the myriad of benefits that comes from being connected to the high-speed Internet."
