5G is the fifth generation of wireless technology. It can provide higher speed, lower latency and greater capacity than 4G LTE networks.
Ping rate (also referred to as "latency") essentially means the time it takes for information from your computer (or console, or other device) to reach the intended server. High ping rate can cause lag and other issues when gaming, while low ping rate (or low latency) makes for a smoother gaming experience.
Typical internet speeds for a workable gaming should be around 3 Mbps download speeds, and around 1-2 Mbps upload speeds. Wondering what speed your existing internet has to offer? Test your internet speed here.
