说明：  4G的速度很快，最高可达1Gbps。那为什么我们还需要更多。问题是 无法提供实时应用程序。5G是下一代移动数据连接的代名词。 它肯定会提供10Gbps到100Gbps之间的高速，而且它将有足够的容量。
(4G is proving good speeds up to 1Gbps. Then why do we need anything more. The problem is that it is not able to provide real time applications. 5G is the name given to the next generation of mobile data connectivity. It will definitely provide great speeds between 10Gbps to 100Gbps and it will have enough capacity.)
