Preface

Communication technology and the communication industry are one of the fastest growing fields since the 1980s. This is true both internationally and domestically. This is one of the important signs of human beings entering the information society. Communication is the exchange of information. In this sense, communication has existed in ancient times. Human dialogue is communication, and people expressing emotions with gestures can also be regarded as communication. People use the beacon to communicate war situations. Of course, the transmission of files between horses and post can also be regarded as communication. Modern communication generally refers to telecommunications.
      The binding effect of information technology on the formation of the world economy is obvious. The advancement of information technology is a natural material condition for the integration or overall enhancement of the world economy. Only when the electronic computer network makes it possible for people to understand the economic changes in any region of the world through the global digital communication network, people realize the role of information and information transmission and processing technology in the integration of the world economy. In fact, it exists in the whole process of the integrated development of the world economy. Natural sciences and philosophy have made significant progress in the study of time and space. Realistic changes in time and space are of great significance to the overall development of the world economy, but they have been neglected in the social sciences.
     With the informatization of society, the communication industry is gradually developing in the direction of convenience, intelligence, and precision, which brings high-level requirements to 5G communication technology. 5G communication technology must not only meet the communication requirements of customers, but also pay attention to customer experience and facilitate customers’ daily life. In this regard, our country should accelerate the development of new technologies and accelerate the application of new technologies, conform to the trend of personalization and universalization of communications, and popularize the application of the Internet of Things. The communication industry of our country will realize the increase in bandwidth, the reduction in cost and the integration of technology, and achieve further development in the global market competition.

前 言

通信技术和通信产业是 20 世纪 80 年代以来发展最快的领域之一。不论是在国际还是在国内都是如此。这是人类进入信息社会的重要标志之一。通信就是互通信息。从这个意义上来说，通信在远古的时代就已存在。人之间的对话是通信，用手势表达情绪也可算是通信。以后用烽火传递战事情况是通信，快马与驿站传送文件当然也可是通信。现代的通信一般是指电信，国际上称为远程通信。
        信息技术对世界经济整体形成的粘合作用，是显而易见的。信息技术进步是世界经济一体化或整体性增强的自然物质条件。只是到了电子计算机网络使人们有可能通过全球数字通信网，全天候了解世界任一地区经济情况变化时，才意识到信息及信息传输、处理技术对世界经济整体化的作用。实际上，它存在于世界经济整体化发展的全过程之中。自然科学、哲学对时空的研究获得重大进展，时空现实变化对世界经济整体化发展的极其重大的意义，在社会科学那里却因其显而易见被忽视了。
        随着社会的信息化，通信行业逐渐向着便捷化、智能化、精确化的方向发展，给 5G 通信技术带来了高层次的要求。 5G 通信技术不仅要满足客户的通信要求，更要注重客户的体验，方便客户的日常生活。对此，我国应当加快新技术研发与应用的脚步，顺应通信个人化、普遍化的趋势，普及物联网的应用，让我国的通信行业实现带宽上的增加、成本上的降低和技术上的融合，在全球化的市场竞争当中取得进一步的发展。
