Why wireless infrastructure can't keep up with crowds
Carriers and venues spend years and tens of millions preparing one stadium for one game. Demand still grows faster than they can build.

Every dollar a venue spends on wireless infrastructure buys a fixed asset sized for a peak that lasts about twenty minutes. The rest of the year it's idle. And when the peak arrives, the asset is already too small.
The numbers are not subtle. One carrier reported five times more data per Super Bowl than a decade earlier. At the 2025 Indy 500, data volume grew 35% year over year to 172 TB in a single day. Per-person data usage at NFL stadiums grew 47% in one year. Super Bowl 59 saw 1.09 GB per connected customer on one carrier, up from 788 MB per Wi-Fi device the year before.
Two years for one game
The response has been to build harder. Preparing one stadium for one Super Bowl took a carrier two years of network work and more than 500 additional antennas. That's the best case: a marquee event with a marquee budget. Most venues, most nights, get the infrastructure they installed years ago.
Temporary events have it worse. Festivals rent cell-on-wheels and pop-up Wi-Fi for tens of thousands of dollars per event, strike it on Monday and rent it again next season. Conferences buy hall Wi-Fi sized for average use that folds during the keynote.
The cost shows up as lost revenue
When the network fails, concessions, ticketing and ordering fail with it. Cashless venues see 15–30% higher per-capita spend, and Mercedes-Benz Stadium reported a 16% lift in its first cashless year. That uplift depends on connectivity. When it goes, transaction throughput drops from roughly 450 to 60 per fifteen minutes.
Nobody files a ticket for a stalled order. The loss shows up later as lower per-caps, longer lines and a sponsor activation that landed after the moment passed.
A different input
Infrastructure scales with spend. The crowd scales with attendance. Every phone in the stands has the radios, battery and compute to be a relay, and the hardware to do it efficiently arrived in the last 18 months. The crowd that overwhelms the network is also the network. That's the premise Zeva is built on.
