Where fundraising event WiFi gets tested
Most of a charity dinner is gentle on a network. Guests arrive, post a photo or two and put their phones away for entrée. Then the MC announces that silent auction bidding closes in ten minutes, and every guest who wants that weekend away picks up a phone at once. Volunteers with bidding tablets walk between tables. That ten-minute window is what the network has to survive.
The second test comes at the end of the night. Winning bidders queue at the payment desk, and each EFTPOS terminal needs a clean connection while three hundred guests book rides home on the same mobile towers. Put the terminals on guest WiFi and the queue slows just when people want to leave.
Separate networks for a charity auction night
A fundraising night usually needs four or five networks, each with its own WiFi name or wired ports, so a guest watching a video can't slow a payment or a bid.
Bidding and donation devices
Volunteer tablets and donation kiosks. This network carries the money-raising traffic, so it is prioritised and its password stays with the event team.
Payments
EFTPOS terminals and the checkout laptop, kept off guest WiFi entirely and tested before doors with a test transaction where your payment provider allows one.
Live stream and AV
The stream encoder and AV laptops on wired ports, with upload reserved for them. If lighting and sound installation comes through our partner AV specialists, their control gear sits here too.
Event staff
Run sheet, registration and messages between the event manager, stage manager and volunteers. Staff carry 1.5 to 2 devices each; plan for the higher figure.
Guests
Sized for the bidding window if guests bid on their own phones. If bidding happens only on volunteer tablets, guest WiFi can be lighter or left out.
Sizing example: WiFi for a 350-guest charity gala
A worked example using our planning starting points; the real numbers are confirmed after a floor-plan review or a walk-through of the ballroom. Try your own figures in the event network planner.
| Who or what | Planning count | Devices |
|---|---|---|
| Guests bidding on their own phones | 350 guests, about 1 device each | 350 |
| Event staff and volunteers | 30 people, about 2 devices each | 60 |
| Bidding and donation tablets | 15 tablets | 15 |
| EFTPOS terminals and checkout laptop | 8 terminals, 1 laptop | 9 |
| Stream encoder and AV laptops | Wired where possible | 4 |
| Total devices to plan for | Busiest moment: auction close | 438 |
| Access points by capacity | About 50 devices per access point | 9 |
| Access points by coverage | 1,100 m² ballroom, about 900 m² each | 2 |
Capacity decides here, not floor area: a ballroom is easy to cover and hard to serve when full. If guests don't bid on their own phones, the count drops.

How much internet a fundraising event needs
Bandwidth follows the same busiest-moment logic. Suppose 150 guest phones are active as the auction closes. At about 0.5 Mbps each, that is roughly 75 Mbps of download before staff, tablets and payments are counted. Terminals use very little bandwidth, but they need it there for every tap.
The live stream is usually what decides the connection. Each stream needs 10 to 20 Mbps of steady upload, with headroom of roughly 1.5 to 2 times whatever the encoder is set to. Many venue and business plans have far less upload than download, so upload gets checked first. The bandwidth calculator gives a starting figure, and the guide to upload speed for live streaming explains the headroom.
Questions to ask the venue before a charity auction
Ballroom venues vary widely. These answers shape the plan, so it helps to have them before we quote.
- Is the venue internet shared with other functions, hotel guests or offices in the building?
- What is the upload speed, not just the download, and can any of it be reserved for the event?
- Are outside WiFi access points allowed, or is there an in-house supplier the venue requires?
- How strong is mobile signal in the ballroom, especially if it is below street level?
- Are there wired network ports at the stage, the AV desk and the payment desk?
- Is there bump-in time to test with the room set before guests arrive?
- Who is the venue's IT or duty manager contact on the night?
What we look after, and what stays with your providers
Our part is the connection, the access points, the separate networks, installation, testing and pack-down; the support level during the night is agreed in your plan. The bidding platform, payment accounts and streaming platform stay with you and your providers. If the auction can't afford a pause, backup internet for events can take over when the main line drops, and our EFTPOS payment networks page covers the payment side in depth.
Questions people ask
Do we need our own WiFi for a charity auction if the venue has WiFi?
Not always. Venue WiFi can work for a charity auction if it is dedicated to your function, has enough upload and lets payments and bidding devices stay separate from guests. Many ballroom networks are shared with the rest of the building, so we check what the venue offers first and add only what is missing, where the venue allows outside equipment.
Can guests bid on their own phones using mobile data?
Guests can bid on mobile data where signal is strong, but a full ballroom shares the same mobile towers, and rooms below street level often have weak coverage. If the bidding platform relies on guests' own phones, guest WiFi sized for the bidding window is the safer plan.
How do you keep EFTPOS working at a fundraising gala?
EFTPOS at a fundraising gala works more reliably on its own payment network, separate from guest WiFi, with every terminal tested before doors open. Where lost payments would be costly, a backup internet connection can be added. Your payment provider can also confirm whether the terminals have an offline mode and what its limits are.
How much upload do we need to live stream a charity gala?
A charity gala live stream needs 10 to 20 Mbps of steady upload per stream, with headroom of roughly 1.5 to 2 times the encoder's bitrate. The encoder should be on a wired port, on a network separate from guests, and tested in the ballroom with the room set, ideally while the bidding platform is also running.
When should we book WiFi for a fundraising event?
Book fundraising event WiFi once the venue is confirmed. If a new internet service is needed, activation time depends on the address and existing equipment, anywhere from a couple of business days to several weeks. Booking early also leaves time to agree equipment positions with the venue and to test the bidding platform on the real network.
