Wi-Fi ISP networks are networks in which an Internet Service Provider (ISP) allows subscribers to connect to a server, called hot spots, via a wireless connection (Wi-Fi). Internet Providers offer a broadband connection so that subscribers can access the Internet from anywhere within the zone covered by the server antenna. Such a zone usually has a radius of several kilometers.

This technology is often used by hospitality chains, entertainment centers, hotels or cities to offer their visitors free access to the Internet.
