第五代无线5G开发计划基于4G，目前正在努力实现其性能目标。通过对3G和4G无线通信系统在体系结构、速率、频带、交换设计基础和前向纠错等方面的比较，发现它们的性能仍然无法解决覆盖差、互联性差、服务质量差和灵活性差等层出不穷的问题。讨论了一种理想的5G模型，以适应3G和4G部署的挑战和不足，以及对早期无线技术的重大系统改进。讨论了4G和5G系统的无线电信道传播特性。重点介绍了5G网络在为终端用户提供个性化服务、终端和网络异构性、智能组网和网络融合等方面的主要优势，评估了该研究对移动的电话和计算机等设备快速有效连接和通信的重要性，包括支持和允许高度灵活的网络连接的能力。
The fifth generation wireless 5G development initiative is based upon 4G, which at present is struggling to meet its performance goals. The comparison between 3G and 4G wireless communication systems in relation to its architecture, speed, frequency band, switching design basis and forward error correction is studied, and were discovered that their performances are still unable to solve the unending problems of poor coverage, bad interconnectivity, poor quality of service and flexibility. An ideal 5G model to accommodate the challenges and shortfalls of 3G and 4G deployments is discussed as well as the significant system improvements on the earlier wireless technologies. The radio channel propagation characteristics for 4G and 5G systems is discussed. Major advantages of 5G network in providing myriads of services to end users personalization, terminal and network heterogeneity, intelligence networking and network convergence among other benefits are highlighted.The significance of the study is evaluated for a fast and effective connection and communication of devices like mobile phones and computers, including the capability of supporting and allowing a highly flexible network connectivity.
