In principle, RefCom4All can be used in all places where there is good wireless internet coverage. WiFi is usually very limited at sports clubs.This is due to the limited coverage, firewall restrictions and / or limited internet speed. We therefore advise not to use WiFi for regular fixtures.
In practice, RefCom4All works best for outdoor sports, such as Hockey, Football, Rugby, Baseball, Cricket, (Outdoor) Beach volleyball, etc.. Hall sports are often due to limited indoor wireless coverage, but also because of the acoustics (=echo), less suitable.
