I've watched a production manager try to run a 3,000-person outdoor event using WhatsApp over a personal phone's data connection because the event Wi-Fi had collapsed two hours before gates opened. The security team couldn't communicate. The bar staff couldn't process card payments. The ticketing system at the gate was scanning QR codes against a local cache that was already 24 hours out of date.
The event Wi-Fi was one of the cheapest line items on the production budget. The total production spend was orders of magnitude higher.
That ratio is insane. And it's not unusual.
The costs nobody puts in the spreadsheet
When event organisers think about connectivity failing, they think about attendees complaining on social media. That's annoying, but it's recoverable. The costs that actually hurt are the ones that hit your revenue and your operations in real time.
Card machine downtime. Every food trader, bar and merch stall running a card terminal needs a data connection. When the Wi-Fi drops and cellular is congested from thousands of phones on one mast, those terminals die. Traders switch to cash-only, except half the audience under 35 doesn't carry cash. Scale that across a dozen traders over a multi-hour outage and the lost revenue across the site is significant. That's not your money directly, but good luck getting those traders back next year.
Ticketing failures. Every major ticketing platform needs connectivity to validate purchases, process on-the-door sales and sync attendance data. When the connection drops, you're turning people away or letting them in unverified. Staff can't process on-site sales, queues build, and the gate experience falls apart.
Production comms failure. This is the one that keeps event managers awake at night, and rightly so. Modern event production runs on IP-based comms, Teams channels, WhatsApp groups, dedicated apps for crew coordination. When the network dies, so does your ability to coordinate security, medical, staging and logistics. You're back to walkie-talkies if you're lucky, and shouting if you're not.
At a corporate conference, a comms failure is embarrassing. At a live event with thousands of people, it's a safety risk.
Why it keeps happening
Event organisers chronically underspend on connectivity. I don't say that to be harsh, I understand the budget pressure. But the pattern is remarkably consistent.
The production budget for a mid-size event will allocate serious money for sound, lighting and staging. Then connectivity gets whatever is left over. It's treated as a utility, like hiring portaloos. The specification is usually "get us some Wi-Fi."
"Some Wi-Fi" typically means a single consumer-grade 4G router. No redundancy, no bonding, no failover. One connection serving ticketing, payments, production comms and public access simultaneously. When 2,000 phones arrive and start hammering the local cell tower, that router doesn't stand a chance.
I'll be blunt: if you're spending less than 1.5% of your total production budget on connectivity, you're gambling. You might get away with it. But when you don't, the downstream costs will dwarf what you saved.
What proper event connectivity looks like
It's not complicated, but it does need to be designed rather than thrown together.
Separate networks for separate functions. Production comms, card payments and ticketing should be on a dedicated, priority network that attendees cannot access. Public Wi-Fi, if you offer it, goes on a separate SSID with bandwidth limits. This isn't about being mean to punters. It's about ensuring that someone posting a story to social media doesn't knock your card terminals offline.
Bonded multi-network cellular. A single SIM on a single network is a single point of failure. What you want is a bonding router aggregating connections across multiple carriers simultaneously. If one network gets congested, and at any large event, at least one will, the others carry the load. We routinely see 80-150 Mbps aggregate throughput from bonded 4G/5G at event sites, which is more than enough for production, payments and ticketing combined.
Satellite as a backup WAN path. At rural or greenfield sites where cellular is marginal, a satellite terminal bonded into the same setup gives you genuine transport diversity. Latency varies and it can struggle in heavy rain, but as one path among several it's excellent insurance.
Deploy and test 24 hours before gates. Not the morning of. Every site is different. RF conditions change with crowd density. Set it up, load-test it, and have time to fix problems before they matter.
The maths event organisers should do
Add up your expected card payment revenue, on-the-door ticket sales and the cost of a safety incident caused by comms failure. Now ask yourself whether the cheapest possible Wi-Fi is really an adequate hedge against losing a meaningful chunk of that.
Proper bonded cellular for a mid-size event costs a fraction of your production budget. But it's the fraction that keeps your card machines running, your gates processing and your traders willing to come back next year.
Connectivity isn't a nice-to-have at events any more. It's infrastructure. Budget accordingly.
