Live IP transmission and bonded cellular connectivity explained: why a packed stadium's cellular network fails at the exact moments a broadcast can least afford it, and how modern connectivity technology keeps the feed on air.
Network testing at a major football stadium recorded drop events accelerating to 5 to 8 incidents within 10 minutes of a goal being scored, with bitrate falling 45 to 50%. By halftime, that rose to 20 to 30 drop events per 15-minute window, with bitrate falling as much as 85 to 90% below baseline. The cause is structural: tens of thousands of fans streaming, posting, and video-calling on the same local cell towers a broadcast crew's uplink depends on.
The fix broadcasters use is bonded IP transmission, combining several independent connections, typically SIM cards from different mobile carriers plus WiFi or wired internet, into one transmission path. If one connection weakens, the others keep the stream moving. LiveU's field units run on this approach through its LRT protocol, and its AI-driven layer, LiveU IQ (LIQ), goes further by continuously analyzing live and historical network data to switch to the best-performing carrier in real time.
At the 2026 Winter Games, sessions using LIQ produced average bitrates more than 36% higher than sessions without it, across nearly 12,000 live sessions and 980-plus field units deployed by broadcasters from 37 countries.
This video covers why crowded venues break ordinary connectivity, what bonded and AI-driven connectivity technology does about it, and what production teams should look for when planning coverage of a high-density event.
