Hello from France,
We are Festiv'IT (http://www.festivit.org or on FB), a small non profit and we deploy WiFi networks in music festivals (non profit only).
Our biggest event is Les Vieilles Charrues (the most populated music festival in France : you can see more pictures on their Facebook).
The network here is mostly based on an AirMax M backbone, we had stability issues with the AC gear, and also only the nanostations M have the secondary port, so we made small masts where we have only a NanoStation and either an UAP5, Picos M2 or UMESHs.
50+ EdgeSwitches throughout the site, 2 EdgePoints are installed on the primary relays.
We have one ERPro but most of the traffic goes through a Mikrotik CCR1036, the ERPros not being powerful enough to handle 5000 simultaneous clients and the rules we need.
As this is the simplest solution, we use "The Dude" in order to monitor our network. We might switch to UNMS when it's ready.
Almost every inch of the 247 acres of the site is covered with UniFi in order to provide a reliable network for the online cashless solution by our friends at Weezevent.
Stats are pretty impressive :
2G Coverage :
5G Coverage :
We installed antennas really everywhere ... even at the top of a big crane for a partner (yeaaah not the most beautiful install)
If the most part of our deployment is used for cashless devices, everything goes through our network. Here is a camera for security purposes, we also have a VoIP network (not ubnt based). On the picture below you can spot a phone between two thin clients used by the medical teams.
To have the best coverage possible for the artists, we use the new UMESHs Pros. Those have provided great results.
If only we could add more than 4 SSIDs, we hope this is planned for future products.
We have so much more to show you ... we would be delighted to have some of you guys from UBNT come over next year (backstage access provided, of course).
