摘要
随着长江数字航道建设的不断深入,长江电子航道图即将正式对外推广应用,这对长江航道全线船岸间的无线通信提出了新的要求。本文分别对中国电信和中国联通两大运营商的3G无线网络进行实地测试,对比分析其信号覆盖情况。在此基础上,就长江航道环境下如何提高通信保障能力提供了技术方案。
With the construction of the digital fairway of the Yangtze River, the electronic channel chart of the Yangtze River is to be applied formally, and it raises new demands on the ship-shore wireless communication of the whole fairway of the Yangtze River. This paper carries out a field test on the 3G wireless network of two operators： China Mobile and China Unicorn, and conducts a contrastive analysis on the signal coverage. On the basis of the study mentioned above, this paper offers a technical proposal on the improvement of the communication security of the Yangtze River fairway.
