目前无线通信是全球发展最快的产业之一,同时,正在进行的信息社会演化被视为促进社会繁荣的重要因素。这个过程涉及许多领域,因此非常需要理解无线通信与信息社会这两个概念的发展及其关系。本研究的目的是为感兴趣的读者提供一个简明的概述,作为继续工作和思考的基础。

本研究从讨论信息社会概念的演变开始,总结目前对信息社会概念的理解,并找出实现这些愿景所需的关键解决方案。介绍了导致当前形势的主要技术发展。无线通信是信息社会的关键推动者。接下来,对无线通信的主要发展趋势进行了研究和讨论,并概述了无线通信技术的发展方向。作者认为应当注意终端和传输技术的发展。最后,讨论了影响用户和市场采用创新技术的动力,尤其强调了技术在此过程中的影响。

Wireless communications is currently one ofthe fastest growing industries globally. At the same time, the ongoinginformation society evolution is seen as important for enhancing prosperity ofsocieties.The process touches many fields, and therefore there is a strong needto understand the developments of the two concepts and their relationships. Theobjective of this study is to provide interested readers with a conciseoverview to serve as a base for continued work and thinking. The study beginsby discussing the evolution of the information society concept, summarizesthecurrent understanding and identifies the key solutions required to make the visionsreality. The main technology developments that have led to the currentsituation are presented. Wireless communications is identified as a key enablerof information society. Next, the major trends in wireless communications areidentified and discussed, and the foreseeable development path of wirelesscommunications technology is outlined. Attention is given both to terminal andtransmission developments. Last, the forces influencing the user and marketadoption of technologies and innovations are discussed. The impact oftechnology in the process is emphasized.
