MatchBeats runs in a modern browser and needs an active internet connection while you operate the board. Venue Wi-Fi can become less reliable as the crowd arrives, so test from the booth under realistic conditions.
Use a wired connection when the venue provides one. Otherwise, keep a phone hotspot available and confirm that your laptop or tablet can switch to it before the match starts.
Open the board early, play several cues through the matchday sound system, and keep your device connected to power. That short rehearsal checks the browser, network, audio output, and levels together.
