文章分析了4G移动技术的关键内核,具有明显优势,要充分发挥其优势,一部分技术会在未来首先突破,但目前4G技术发展还面临不少问题,我们必须努力学习,尽快解决。无线通信网络是4G移动技术的发展基础,4G移动技术之所以能够发展成为新时代的信息传递技术,是因为它能够高速传输数据,以高水平方式抗干扰,具有较强的兼容速率,在今后若干年内每一位关心中国通信事业发展动态的研究者都会重点关注4G移动技术的发展 The article analyzes the key kernel of 4G mobile technology and has obvious advantages. To give full play to its advantages, some technologies will break through in the future. However, the development of 4G technology still faces many problems. We must study hard and solve as soon as possible. The wireless communication network is the foundation for the development of 4G mobile technology. The reason why 4G mobile technology can be developed into a new era of information transmission technology is that it can transmit data at a high speed and resist interference with a high level, and has a strong compatible rate. In the future In the past few years, every researcher concerned with the development of China’s telecommunications industry will focus on the development of 4G mobile technology
