中国におけるTD-SCDMA向け450MHz周波数割当ての可能性：評価と予測
Assessing the Possibility of 450MHz Spectrum Allocation in China to TD-SCDMA and Its Implications
|
Abstract
Spectrum resources are a basic requirement for the development of mobile
communications networks. At the same time, spectrum planning also impacts the
future development of the mobile communications industry. In June 2009,
China' s Ministry of Industry and Information Technology conducted research on
issues concerning planning for the 450-470MHz spectrum band. It did not rule
out the possibility of allocating this low-frequency band to TD-SCDMA. If
450MHz, which can help to solve communications problems in China' s remote
rural areas, will be allocated to TD-SCDMA, the industry will pay close
attention to whether this will help the penetration of TD-SCDMA services in
China and benefit R&D for TD-LTE and TDD. This report examines the Chinese
government' s planning for the 450MHz band, and analyzes the possibility that
this spectrum band will be allocated to TD-SCDMA and its applications.
