In another development that may raise the stakes substantially for the upcoming 700 MHz auction, participants at the 2007 World Radiocommunications Conference (WRC-2007) sponsored by the International Telecommunications Union (ITU) approved usage of the 700 MHz band for advanced wireless or International Mobile Telecom (IMT) services on a global scale, with variations on specific frequencies and implementation that depend upon the ITU region to be served. By 2015, the agreement is expected to spur the deployment of WiMax and mobile TV networks worldwide that use a common set of frequencies and technical standards. Observers believe that the resulting economies of scale will make it possible for wireless operators and equipment manufacturers to roll out advanced wireless broadband services and devices faster and less expensively, to the benefit of consumers. Specifically, WRC-2007 delegates adopted usage of the 698-806 MHz band for IMT services in ITU Region 2 (i.e., North and South America) and for nine Asian nations in ITU Region 3 that include China, India, South Korea, Singapore and Japan. In ITU Region 1, which covers Europe, Africa and the Middle East, the upper portion of the 700 MHz band (i.e., 790-862 MHz) was reserved for IMT use. Although the U.S. and other nations currently in the midst of the digital television (DTV) transition are expected to implement advanced 700 MHz wireless services prior to 2015, such deployment is not expected until 2015 in Europe, where broadcasters retain a larger share of 700 MHz UHF spectrum and where the transition to DTV has just begun. (China, which must coordinate its spectrum with Russia, is expected to follow the same timetable.) The accord represents a major victory for the U.S. delegation, which spearheaded the movement toward a global approach on IMT spectrum use.
