由我校通信与控制工程系讲师蒋忠勇、姚光圻等与北京电信管理局共同完成的《北京市900兆赫电波传播特性的测试与研究》科研项目,十一月四日在北京通信学会、北京电信管理局组织的评审会上通过评审。当前城市无线电移动通信发展迅速,现今使用的150和460兆赫频段已十分拥挤,迫切需要开辟900兆赫的新频段。由于城市建筑物对移动通信电波传播特性的影响,这方面虽然国外已有实测资料,但我国目前还是空白,因此,这一研究具有实用价值和较
The research project “Test and Research on 900 MHz Radio Wave Propagation Characteristics of Beijing Municipality” jointly conducted by lecturer Jiang Zhongyong and Yao Guangtao of Communication and Control Engineering Department of our university, and Beijing Telecommunication Administration will be held on Nov. 4 at the Beijing Institute of Communications, Beijing Telecom The review organized by the Authority passed the review. The current rapid development of urban radio mobile communications, the 150 and 460 MHz frequency bands used today are already very crowded, there is an urgent need to open up a new band of 900 MHz. Due to the influence of urban buildings on the radio propagation characteristics of mobile communications, although there are some measured data in this area in our country, there is still no blanket in our country at present. Therefore, this research has practical value
