Overcoming High-Density RF Congestion
Broadcasting live sports in packed stadiums presents immense radio frequency (RF) challenges. Tens of thousands of spectator smartphones clog standard 2.4GHz and 5GHz Wi-Fi channels, leading to severe packet drops on traditional cloud RTMP links.

Stadium Network Hardening Checklist
- DFS Channel Locking: Use Dynamic Frequency Selection (DFS) 5GHz channels (Channels 52-144) unused by spectator mobile phones.
- Directional Patch Antennas: Mount directional panel antennas on sideline production carts pointing at camera operators.
- Local UDP Remuxing: CastZero UDP transport recovers lost packets instantly without blocking video rendering.
