Is this a municipal WiFi system? Will it work well in a town or city, or a campground or RV park? Will it support a lot of users?

No; this is a system that is designed specifically for extending the Local Area Network (LAN) of a home or rural business over a large geographical area. It does not work well in a municipal setting, because the high levels of interference negate the advantages of the high-gain antennas we use on the AyrMesh Hubs. Most of the outdoor WiFi market are aimed at “density” – hundreds, thousands, or tens of thousands of devices in a relatively small area – up to a couple of hundred acres – and they do a VERY good job. The AyrMesh system is aimed at exactly the opposite: up to a couple of hundred devices spread out over hundreds, thousands, and tens of thousands of acres. Additionally, the AyrMesh system does no routing, filtering, or throttling, so devices connected to the AyrMesh devices have full access to the underlying network. There is no facility for client isolation (to prevent users from accessing each other or devices on the underlying network), MAC address whitelisting/blacklisting (although MAC addresses are easily “spoofed”), or provision of a “captive portal” (a web page forcing users to agree to terms and conditions before connecting to the network). These are all very desirable options if you providing “guest” WiFi to people, and AyrMesh does not currently provide any of them.
