Cader NetworksWhy shows and marts are a different job to a wedding or festival
A wedding needs WiFi for a few hours in one marquee. A county show or livestock mart needs internet across a whole showground for a full day or more, with dozens of independent trade stands each running their own card machine, a main ring that might be live-streaming or running a PA and results system, and increasingly digital catalogue or pedigree lookup systems that traders and buyers expect to work instantly. None of that can be on the same network as casual visitor WiFi, if a crowd streaming video from the car park slows down a stallholder's card payment, that's a real financial cost to someone on the day.
Segregating trade payments from public WiFi
This is the single most important design decision. We put trade stands and payment terminals on their own prioritised, isolated network, separate from general public WiFi, so a busy public network never affects a card transaction. It's the same principle we use for event WiFi generally, just applied at the density a show demands, sometimes 50-100+ individual payment terminals across a showground.
Coverage across a real showground
Showgrounds are typically open fields, sometimes with permanent buildings dotted around, main ring, exhibition halls, a food court, trade rows. Each area gets planned separately against its own expected footfall rather than one blanket signal, the main ring at peak time behaves completely differently to a quiet trade row at 9am. Where there's no existing power or cabling, generator power and either cabled runs between access points or a wireless mesh bridge covers the gap.
The uplink for a genuinely rural showground
Most Welsh agricultural showgrounds sit well outside strong fixed-line coverage. A bonded 4G/5G uplink, often with two routers on different networks for redundancy, is the usual answer, and for the more remote sites, or ones with a track record of unreliable mobile signal on the day, Starlink as the primary or backup uplink increasingly makes sense, dish up, generator running, live in twenty minutes.
What to ask us, or any supplier, before you book
- Will payment terminals be on a genuinely separate, prioritised network from public WiFi?
- How is the site being surveyed, from a map, or in person?
- What's the redundancy if the primary uplink drops during the busiest hour of the show?
- Is there support on-site during the event, or is it drop-and-hope?
We've covered shows including the Aberdyfi Soap Box Racing Charity Event, Heart of Wales 7s and Brecon County Show. If you're planning a show or mart, tell us the site, expected footfall and number of trade stands, and we'll come back with a proper plan, survey included for anything beyond a small local show.
