What attendee WiFi has to handle
Guest WiFi gets judged at the worst possible moments: everyone arriving at once, the break after a keynote, the minute a speaker says 'scan this code'. Average use across the day is usually modest. The peaks are not, and a guest network sized for the average struggles at exactly the times people notice.
Guest devices also behave differently from staff devices. They join and leave constantly, they upload photos and video, and plenty of them start background updates the moment they find a connection. Good public WiFi for events plans for all of that, and keeps it well away from the networks your own team depends on.
Sizing guest WiFi for events: starting points
Based on about one device per attendee and roughly 50 devices per access point. Coverage can add more, and everything is confirmed on-site.
| Attendees at the busiest moment | Guest devices to plan for | Access points for capacity |
|---|---|---|
| 100 | About 100 | 2 |
| 250 | About 250 | 5 |
| 500 | About 500 | 10 |
| 1,000 and above | About 1,000 or more | 20 or more, designed per site |
Often fewer devices are active than connected. Staff, payments and production are counted separately on their own networks. For crowds in the thousands, see WiFi for large crowds.
Guest WiFi settings we agree with you
Network name
Short, obvious and spelt exactly as it appears on signage, so guests don't pick a neighbouring network by mistake.
Password or open
A simple password on signage keeps out passers-by and makes it clear which network is yours. We'll talk through whether an open network suits your event.
Per-device limits
A cap on each device's share, so one person syncing a photo library can't slow the network for the whole room.
Guest isolation
Guest devices kept from seeing each other where the equipment supports it, which reduces nuisance and risk.
Coverage zones
Which areas get guest WiFi, such as seating, foyers and exhibition floors, and which don't, like back-of-house.
Hours
Whether guests need the network outside event hours, or whether it can be switched off once they leave.

Keeping guests away from staff and payments
The guest network is the busiest and least predictable network at any event, so it never shares space with the things that keep the event running. Staff devices, card terminals, ticket scanners, cameras and streaming gear each sit on their own network with their own password. Guests can't see them, and a busy guest network can't take their share of the connection. Our guide to separate networks for events explains how this works.
This matters most for payments. A crowded guest network slowing the bar's terminals costs real money, which is why we recommend a dedicated EFTPOS payment network whenever there's trading on-site. To see how many access points your crowd needs, try the event network planner.
Event guest WiFi checklist
Small details that save a lot of questions at the help desk. More in our guest WiFi best practices.
- Network name and password on signage at entries and seating
- The same details in the event app, program or name badge
- Signage near the busiest spots, not only at registration
- Desk staff know the network name and password
- Guest network tested from the far corners and the foyer
- Per-device limits set before doors open
- Guest WiFi checked again once the room fills
- A short answer ready for guests whose device won't connect
Questions people ask
How many people can event guest WiFi support?
Guest WiFi is sized to the event rather than capped at a fixed number. We plan about one device per attendee and start from roughly 50 devices per access point, then check coverage across the space. A 100-person seminar might need two access points for capacity, and a 500-person exhibition around ten, with more where walls or layout demand it.
Should event guest WiFi have a password?
Usually, yes. A simple password on signage keeps out people passing by, makes it clear which network is yours and gives you some control over who uses it. Open networks are easier to join but invite everyone within range. Either way, guest WiFi should be completely separate from staff, payment and production networks.
Why is guest WiFi at events so slow?
Most often because too many devices share too few access points, the connection's upload is too small, or guests share a network with staff and payments. Events also have sharp peaks, like arrivals and breaks, when everyone connects at once. Sizing for the busiest moment and setting per-device limits deals with most of it.
Can guests see other devices on the event WiFi?
They shouldn't. Where the equipment supports it, EventWiFi isolates guest devices from each other on the guest network. Guests can't reach staff, payment, camera or production networks at all, because those run as separate networks with their own passwords. That separation is part of every event network we plan.
Do I need guest WiFi at my event?
Not always. If attendees mostly use their phones briefly and mobile signal is good, guest WiFi may be a nice extra. It matters more when the venue has poor mobile coverage, the crowd is large, there's an event app or live voting, or exhibitors and attendees expect to work. Payment and staff networks usually come first.
Can you limit how much each guest uses?
Yes, with per-device limits. Each device gets a cap on its share of the connection, so one person streaming or syncing photos can't slow the network for everyone. Limits are set from the connection size and expected crowd, and can be adjusted during the event within the support level agreed in your plan.
