Large scale WiFi deployment

Setting up large wifi networks for campusses or outdoor is quite a challenge.

- hardware -

The hardware allows different functionalities. Generally you need AP's (Access Points), maybe repeaters and a management system. AP's have a maximum amount of concurrent / simultaneous users.

Cisco Enterprise Wifi - Enterprise APs have a max of 24 simultaneous users, making this expensive and useless for large deployments

Netgear - has bugs with wireless N. Don't use!

Ruckus - highly recommended

Ubiquiti - new and in heavy development. A bit experimental but promising

- management and billing -

For management and billing you have several options, which include determining who your users are, printing vouchers, walled gardens, being able to change the default page, filtering by MAC address, etc. Most couple with a radius server.
