Commentators often focus on the super-fast speed of 5G. However, for gaming it's not the whole story. In fact, users will benefit most from the low latency possible with a 5G network for online multiplayer games such as Fortnite, and cloud gaming applications such as Xbox gaming.
Latency refers to the time it takes a gaming device to send data to the corresponding server and then receive it back. The higher the latency, the more "lag" experienced by the user. In other words, there's a noticeable delay between the player's input and the server's reaction, which makes for a disjointed, unsatisfying gaming experience. Almost as frustrating for users is "jitter" (also known as "ping spikes" or "stuttering"), which is the fluctuation of latency over time. This makes for highly unpredictable gameplay which can make things extremely challenging for players.
According to Ericsson, the good news about 5G gaming is that 5G latency is expected to be significantly lower than 4G latency. That can make a major difference to the gaming experience—delivering smoother gameplay even with large numbers of concurrent users on the network. This is particularly important for competitive gaming. Where previously players with faster connections had an advantage, 5G gaming could level the playing field and encourage even more users to try their hand at e-sports, competitive first-person shooter (FPS) titles and other games.
