4G LTE cell tower has a max range of 3 miles/5km for Internet data and 10 miles for voice calls. It's cell signals are line-of-sight and can be blocked by dense objects like walls, tall buildings, hills, forests, heavy rain, etc.
....... 3G/4G cell towers are usually located in city areas and along main roads and highways(= cater for car nav apps like Waze).

4G LTE = about 30Mbps.
3G = about 2Mbps.

.
The latency/ping/input-lag for wireless 4G modem-router is slightly higher than wired Fiber Ethernet modem-router by about 10 milliseconds.

Latency is very dependent on the location of the online game server, ie should be not > 1,200 miles away = not > 45 ms for wired Fiber Internet. For wireless 4G LTE Internet = not > 1,000 miles away.
....... For a player located in the Klang Valley, the online game server should be located in KL, Singapore, Thailand or thereabouts, ie not faraway in China, HK, Taiwan, Japan, SKorea or USA/Europe.
