摘要
本文首先简要介绍了移动通信系统的发展历程,然后对3GPP系统、3GPP2系统和WiFi等宽带技术的标准、特点,系统参数、网络结构、应用范围和演进方向等进行了详细地比较和分析,重点讨论了3GPP系统无线接入网络演进过程中各种技术的标准、优缺点、改进措施及进一步演进,最后展望了未来移动无线通信的研究热点和发展趋势。
In this paper, the development course of mobile communication systems is firstly introduced in brief. Then, the broadband technologies in 3GPP systems, 3GPP2 systems and WiFi are detailedly compared and analyzed, which include standards, characteristics, parameter of systems, network structure, scope of application and evolution. 3GPP systems are emphatically discussed, which include standards, advantages and disadvantages, improvement measures and further evolution. The interested issues and development trends of next generation mobile wireless communication are finally prospected.
