Why quotes vary 10×
One vendor quotes AED 25,000. Another quotes AED 250,000. Both are pitching "event WiFi" for the same venue. The gap is not greed — it is scope. Most cheap quotes assume you do not need redundancy, do not need on-site engineers, and do not really care if the network drops during the keynote. Most expensive quotes assume you do.
The real cost drivers
Three things move the price more than anything else: concurrent user density, redundancy level, and on-site engineering hours.
Concurrent users: a 500-person conference with corporate-grade WiFi is not the same as a 5,000-person event where every attendee is streaming. The latter needs three to five times more access points per square metre.
Redundancy: single uplink, dual uplink, or fully diverse path? Single APs or paired redundant pairs? Hot-swap controllers or single controller? Each step roughly doubles the kit cost.
On-site engineers: a single engineer for setup-only is cheap. A tiered on-site team during the event is not. If your event runs ten hours per day for three days, expect 60+ engineer-hours just on-site, before remote NOC support.
What an honest scope conversation looks like
It starts with how many people, doing what, for how long. Then: what is the cost of a 30-minute network outage during the event? That number determines redundancy level. Then: when does the venue open for setup, when must the event be live? That determines team size and shift count.
Where vendors cut corners
Predictive RF design skipped. Single-radio APs in a venue that needs dual-radio. No spare controller. Bandwidth contracted on a residential-grade circuit. One engineer running three venues at once. Each of these saves money up front and creates the failure that ruins the event.
A reasonable ask
When you receive a quote, ask three things: how many APs and what model, what is the redundancy at the controller and uplink, and how many engineer-hours are budgeted. If a vendor cannot answer those quickly, the quote is built on assumptions you have not seen.
