Zusammenfassung
TL;DR
A single SIM card isn't enough for professional live events. AlwaysOn Bonding combines 4–6 connections for over 450 Mbit/s upload — proven at the Sport Austria Finals 2025 with 800GB of live streaming over 3 days without a single outage.
The Problem: One Network for Everything Isn't Enough
Imagine: the opening ceremony of your conference is running. 500 people in the room, another 3,000 online. The host stands at the podium. And then the live stream drops.
No error message, no warning — just a black screen for all online viewers. The damage is done before you can react.
This is the core problem with event internet: a single point of failure is enough to destroy everything. And most event setups have exactly that single point of failure.
What Depends on One Connection
At a modern event or trade show, a single internet connection carries:
- Live streaming: 10–50+ Mbit/s upload depending on quality and number of streams
- Registration & accreditation: Ticket scanners, badge printers, guest list tablets
- Presentations: Cloud slides (Google Slides, Canva), video playbacks
- Video conference connections: Remote speakers via Zoom or Teams
- Moderation tools: Slido, Mentimeter, live voting systems
- Payment processing: Merchandise stand, cloakroom, catering
- Communication: Staff chat, walkie-talkie replacement via mobile
A single SIM card typically has 10–30 Mbit/s upload on urban 5G networks — under load, with hundreds of nearby devices, this can be significantly less.
What Happens During an Internet Outage at Events
Live Stream: Thousands of Viewers Lose the Picture
An interrupted live stream is not just a technical problem — it's real-time reputational damage. When 3,000 online viewers suddenly see a buffering video or black screen:
- Social media reacts immediately: "The stream crashed" goes viral in seconds
- Sponsor visibility is lost: Logos and mentions during the outage — gone
- Recording has gaps: Even if the stream resumes, the recording is compromised
- Trust in the organizer: Once ruined, hard to rebuild
Registration: The Queue Grows
When the registration system goes offline, the result is a physical queue that quickly becomes unmanageable. Non-functioning ticket scanners mean manual checking — entry time doubles or triples.
At large events, this can become a safety issue.
Presentations & Technology
Cloud-based presentations (Google Slides, Canva Live) need a constant connection. When it drops:
- Presentation freezes on the last loaded slide
- Embedded videos cannot play
- Remote speakers are disconnected and must redial
- Q&A tools (Slido) no longer show new questions
Payment Processing at Events
Merchandise stands, catering and cloakrooms — everything runs on card payment. An outage during the evening peak of a concert or trade show means:
- Cashless-only stands cannot sell
- Queues build up quickly
- Frustrated visitors who abandon their purchases
Case Study: SAF Sport Austria Finals 2025
The Sport Austria Finals 2025 were the ultimate stress test for event internet.
Key facts:
- Duration: 3 days of continuous operation
- Data volume: 800GB transferred
- Peak upload: 450 Mbit/s
- Connections: 3x 5G (A1 + Magenta + Drei)
- Outages: 0
- Setup time: 30 minutes
groox Filmproduktion was responsible for the entire livestream production. Any interruption would have been immediately visible to tens of thousands of viewers — live, with no second chance.
The solution: AlwaysOn combined three 5G connections from three different Austrian providers. Bandwidth was not only aggregated but also intelligently distributed: critical streaming packets received priority, while administrative tasks (backup uploads, monitoring) were distributed across remaining capacity.
The result: professional live stream quality for 3 days, 800GB data transfer, not a single connection drop.
The relevance for events of all sizes: If AlwaysOn works under these extreme conditions, your conference, trade show, or corporate event is comfortably covered.
Internet Bonding for Events: How It Works
Multiple Connections, One Network
AlwaysOn combines up to 6 different connections:
- Mobile 5G/LTE SIMs: A1, Magenta, Drei — different providers, independent towers
- Fixed line: If available at the venue
- Starlink: For outdoor events or locations without 5G coverage
- WiFi bridges: For specific location requirements
Bandwidth is truly aggregated — not just failover. Three 5G connections at 150 Mbit/s upload each yield 450 Mbit/s upload. That's enough for multiple parallel 4K streams.
Automatic Failover in < 1 Second
If a SIM fails — technical defect, provider overload, physical damage — the remaining connections take over immediately. The streaming software doesn't notice. The stream continues.
Portable Setup
The AlwaysOn box is portable and works without fixed infrastructure. For events this means:
- No network pre-arrangements at the venue needed
- 30-minute setup by own staff possible
- Transportable from event to event
Typical Event Requirements and AlwaysOn Solution
| Event Type | Typical Requirements | Recommended Config | Upload Capacity |

| Conference (200 people) | 1x stream, registration, presentation | 3x 5G (A1+Magenta+Drei) | 150–300 Mbit/s |
| Trade show (1,000+ people) | 2-4 streams, payments, registration | 4x 5G + fixed line | 300–450 Mbit/s |
| Sports event | Multi-camera streaming, results | 4-6x 5G + optional Starlink | 450+ Mbit/s |
| Concert/festival | Streaming, cashiers, social media | 3-4x 5G + Starlink | 300–450 Mbit/s |
| Corporate event | Hybrid meeting, presentations | 3x 5G | 150–300 Mbit/s |
On-Site Setup: 30 Minutes to Stable Connection
AlwaysOn is explicitly designed for deployment by event staff without IT background.
Setup process:
- Unpack box and SIM cards — delivered pre-configured
- Insert SIM cards — A1, Magenta, Drei SIMs into corresponding slots
- Connect power — standard outlet or mobile power bank
- WAN connection (optional): if fixed line available at venue
- Configure WiFi — SSID and password pre-configured
- Test: Speed test shows aggregated bandwidth — setup complete
No IT technician, no networking expertise, no long lead time needed.
Frequently Asked Questions
What's the difference between AlwaysOn and a single SIM hotspot?
A hotspot with a single SIM has one connection — if it drops, everything is gone. AlwaysOn combines multiple SIMs and aggregates their bandwidth. The difference: 30 Mbit/s from one SIM vs. 450 Mbit/s from three combined — and when one drops, the others keep running.
How much upload bandwidth do I need for live streaming?
Rule of thumb: 1080p stream = 6–10 Mbit/s upload. 4K = 20–30 Mbit/s. With redundancy, plan at least 3x the stream requirement as total bandwidth. For two parallel 4K streams plus registration and payment, we recommend at least 150 Mbit/s upload.
Is on-site support available?
Yes, Werner.Solutions offers optional on-site support for large events. For smaller events, phone support during setup and operation is sufficient.
Rent or buy?
AlwaysOn Event (€199/day) is ideal for individual events. Those who run events regularly (6+ per year) are better off with AlwaysOn Business (€149/month). Both options include monitoring by Werner.Solutions.
What if there's no 5G network at the venue?
In this case, Starlink can be integrated. Starlink delivers 50–200 Mbit/s upload worldwide — combined with available 4G connections, this provides reliable performance even at remote locations.
Conclusion
Event internet is too critical to leave to chance. A single outage in front of hundreds or thousands of spectators can permanently damage an event brand's reputation.
AlwaysOn proved what it can do at the Sport Austria Finals 2025: 800GB, 3 days, 0 outages.
