What happens if the internet drops right when people are coming in? If access control is set up properly, nothing: the scanners keep validating in offline mode and the operation doesn’t stall. The key isn’t having “good connectivity,” it’s not depending on a single one. Connectivity is the most sensitive point of any access control, and it’s covered with several layers.
At SOMOS DER we design the entire operation with redundancy, precisely so we don’t depend on the venue WiFi. Here’s how it works.
The most common mistake: trusting the venue WiFi
A venue’s WiFi is built for general use: browsing, social media, email. Not for validating thousands of simultaneous entries at the door. When the crowd arrives, it saturates, it drops or it simply doesn’t reach every access point.
Leaning access control on that network alone is the recipe for lines and embarrassment. That’s why the first thing we do is set up our own connectivity, independent of the venue’s.
The three backup layers
Serious access control doesn’t have one plan B: it has several.
1. Offline cache on the scanners. Each scanner holds the attendee database locally. If the network drops, it keeps reading QRs and recording entries with no connection. When the network comes back, it syncs everything with the central system. It’s the first line of defense.
2. Automatic 4G backup router. If the main connection fails, the system jumps to a 4G mobile network without the operator having to do anything. The transition is automatic.
3. Starlink antennas. For remote grounds, outdoor events or areas without good signal, we add Starlink satellite internet as an extra layer. Where the cable and the 4G don’t reach, the satellite does.
Why redundancy always wins
The right question isn’t “will the connection fail?” — it’s “when?”. At a real event, something always goes sideways: a power cut, a router that overheats, a crowd that saturates the antenna. The difference between an event that keeps going and one that jams is how many backup layers you had ready beforehand.
That’s why we don’t sell “good connectivity”: we design the operation so that entry doesn’t stop even if an entire layer goes down.
The proof: entire tours without stalling the door
We run tours of dozens of dates — like Abel Pintos (30 dates) or Anuel AA (4 dates, 60,000 fans) — where every night is a different venue with its own connectivity reality. And 100% remote events like FILGUA in Guatemala (90,000 visitors over 13 days), operated from a distance. Redundancy is what makes it possible to sustain that standard date after date, country after country.
Connectivity is invisible when it works and catastrophic when it fails. We cover it with several layers so you never even notice. Take a look at our access control and accreditation service.
