| 摘 要： | 5G相比4G,网络容量更大、峰值速率更快、连接数量更多,但几十Gbps的峰值速率、10Tbps/Km2的流量密度,仅仅依靠目前分配的中、低频段,最大100MHz的带宽是根本无法实现的。毫米波利用其丰富的频谱资源,能很好的满足5G连续大带宽频频需求。本文对毫米波在无线通信中的优劣势进行分析,并介绍毫米波在5G中的应用场景,最后通过测试结论证明通过使用毫米波提高系统速率、容量的可行性。

| Abstract: | Compared with 4G, 5G has larger network capacity, faster peak rate and more connections. However, the peak rate of tens of Gbps and the traffic density of 10Tbps / km2 can not be realized at all only depending on the current allocated medium and low frequency segments, and the maximum 100MHz bandwidth. Millimeter wave can meet the needs of 5G continuous large bandwidth frequency with its rich spectrum resources.This paper analyzes the advantages and disadvantages of millimeter wave in wireless communication, introduces the application scenario of millimeter wave in 5g, and finally proves the feasibility of using millimeter wave to improve the system speed and capacity through the test conclusion. |
