| Abstract: |
| Digital dividend spectrum has great significance for the development of public mobile communications. Firstly,the trend of global mobile communication is analyzed,which indicates the rapid growth of spectrum requirements,especially for digital dividend spectrum. Secondly,by overviewing of the current analog-to-digital conversion status of global terrestrial broadcasting television,the implementation of digital dividend spectrum in mobile communication is analyzed from two different dimensions of international standardizations and the world’s major regions. Finally,the opportunities,challenges and issues raising with global digital dividend are summarized,while some proposals on appropriate spectrum usage of future digital dividend spectrum are provided as well. |
