Efforts to improve latency were started with the introduction of 4G but it was never the main objective. However, this is not the case with 5G, where latency has been an integral part of the development of 5G technology. In an ideal situation, the time taken for a signal to be received by a base station transmitted from a mobile device on a 5G network should be 1-2 milliseconds! This is a major improvement from 4G LTE, which was already a significant improvement over the previous 3G technology. Verizon has reported that their 5G network achieves a latency of lower than 30 ms, which is an improvement of around 23 ms compared to the existing 4G network which takes over 53 ms.

按网上搜到的说法都是说5g可以降低手机到基站的延迟，然而为什么在同一地点5g基站到我ping的ip地址的延迟会比4g基站的高呢，我暂且蒙古。另外我在多个地点的固定位置测试过很多次，都是4g比5g延迟低，应该不属于个别现象。
