The World Radio Conference in ***2 (WRC**2) allocated ***0 ~ ***0
MHz and ***0 ~ ***5 MHz as the 3G TDD core frequency band. In
China, the ***0 ~ ***0 MHz band is added as a supplementary TDD
band. As the only 3G TDD technology supported by many
manufacturers, TD-SCDMA is the most suitable system for this
frequency band. The same frequency bands allocated for TD-SCDMA
globally laid the foundation for the wide deployment of this system
throughout the world, while being conductive to global roaming.
