How to run an event network that holds.
A plain guide to event connectivity: why the WiFi and EFTPOS fall over when the gates open, what a real event network is made of, and how to make sure the network is not the thing that goes wrong on the day.

Why event networks fail
Most venues run a network sized for a normal day, not a peak crowd. When thousands of phones and EFTPOS terminals connect at once, the access points and the single internet connection saturate, so payments drop and the queues stop moving. The organiser cops it, not the venue.
The fix is not a bigger 4G box. It is infrastructure designed for the peak load, with bonded backhaul across carriers and separate networks for payments, staff and the public, so one bottleneck cannot take the whole event down.
What a real event network is made of
Six layers that turn a venue with patchy signal into a network that holds from gates open to the headline set.
Payments first
EFTPOS and POS on their own VLAN with priority, so a busy public network can never slow a transaction.
WiFi sized for the peak
Separate staff, vendor and public WiFi, with enough access points for the real device count, not the average.
Bonded backhaul
Multiple 4G/5G carriers plus Starlink, bonded and failing over automatically, so one carrier dropping is a non-event.
Ticketing and gates
Reliable scanning at the gates so the queue keeps moving and the entry data is clean.
CCTV and comms
Crowd-safety cameras and two-way comms on the same managed network.
A crew on site
People on the ground watching a live dashboard for the whole event, reinforcing a node before it drops, not a phone hotline.
An event network vs a 4G box
The difference between hoping it holds and knowing it will.
How it comes together
We walk the site
We map the areas, the crowd flow and the load, and design the network and the backhaul to suit.
We build and test before doors
The network is installed and load-tested before the gates open, so problems are found in rehearsal, not in front of the crowd.
We run it live, then report
A crew runs it for the whole event and hands you a report of how it performed.
Who builds it
Event Networks is the event and temporary-network service of Alien IT Solutions, an Australian IT, networks and connectivity company with more than 15 years of experience. The same team builds permanent networks for businesses and rural properties, so an event network is built to the same standard as one meant to last.
Remote and rural events lean on the sister services too: Starlink Rural for satellite backhaul where there is no fixed line, and Long Range WiFi for long-range links across a site. All are Alien IT Solutions.
Questions organisers ask
Why does event WiFi and EFTPOS fail when the crowd arrives?
Most venues run a network sized for normal days, not a peak crowd. When thousands of phones and EFTPOS terminals connect at once, the access points and the single internet connection saturate, so payments drop and queues stop moving. The fix is infrastructure designed for the peak load, with bonded backhaul and separate networks for payments, staff and public.
Is a 4G box enough for an event?
For a small stall, sometimes. For an event with vendors and ticketing, no. A single 4G box has no failover and shares one tower with the whole crowd. An event network uses bonded backhaul across multiple carriers and Starlink, with payments on their own protected path, so one carrier dropping does not stop the show.
How do you guarantee EFTPOS uptime?
Payments are put on their own VLAN with priority over everything else, carried on bonded backhaul that fails over between carriers automatically. The network is built and load-tested before doors open, and a crew watches a live dashboard during the event, so an access point near capacity is reinforced before it drops a single transaction.
Do you provide crew on the day?
Yes. Event Networks walks the site, builds and tests the network before doors, then runs it live with a crew on the ground for the whole event, not a phone hotline. After the event you get a report of how it performed.
