随着4G正式商用大幕的开启,国内无线频谱资源够不够用?我国主导的TD-LTE目前最急需什么频谱资源?成为业界普遍关心的问题。“目前,欧美等发达国家和地区已经或正在着手将‘数字红利’频段分配给FDD-LTE使用。从长远看,我国TDLTE的发展仍然面临缺少1GHz以下优质频谱资源的挑战。”在接受本刊记者采访时,工信部赛迪智库无线电管理研究所的彭健博士表示,缺乏优质低频资源,或影响我国TD-LTE网络快速普及。
With the opening of the official commercial curtain of 4G, the domestic wireless spectrum resources are not enough. What is the most urgently needed spectrum resource for China’s leading TD-LTE? It has become a common concern in the industry. At present, the developed countries and regions in Europe and the United States have already started or are planning to allocate the ’digital dividend’ band to FDD-LTE for use. “In the long run, the development of TDLTE in our country still faces the challenge of lacking high-quality spectrum resources below 1GHz.” In an interview with this reporter, Dr. Peng Jian, director of Institute of Radio Management at CCID think-tank of the Ministry of Industry and Information Technology, said that the lack of high-quality low-frequency resources or the rapid spread of China’s TD-LTE network.
