无人驾驶技术即将改变人类科学技术。无人驾驶技术为什么需要5G技术配合呢？
这是因为无人驾驶车辆需要处理大量的计时信息，而且需要做到快速和细致，5G网络技术可以满足这一需要，因此当5G技术成熟且普及的时候，无人驾驶技术也将可以普及。
比如当无人汽车在路上行驶的时候，它对道路的规划、以及道路上车辆的情况等需要随时做出及时处理，因此它的行使地图和路况信息需要实时更新，实时和车辆管理系统沟通，无人驾驶车辆通过传感器、摄像头采集到的信息数据量很大，对网络通道的速度、带宽以及数据传输时效性都很苛刻，而且需要大数据云技术的辅助，4G网络还满足不了，5G网络技术可有效满足。
无人驾驶技术的前提条件是网络技术低延时高带宽的特征，正是无人驾驶技术最需要的，刚好5G网络满足。如果带宽不足的话，那么数据就不能及时传输，无人驾驶车辆就不能对地图和路况信息做出及时调整，那么它在行驶的过程中就很容易出现问题，甚至激发某种事故。
相对4G网络，5G网络的传输速率提升100倍，其峰值传输速率达到10Gbit/s，所以单位数据的传输用时将会非常短，我们用4G网络下载一部1g容量的电影，大致需要半分钟，而使用5g网络技术不到一秒钟就能完成，这样的速率就可以满足车辆在道路上行驶时出现紧急情况的数据处理。
