Wi-Fi, also, WiFi, Wi-fi or wifi, is a brand originally licensed by the Wi-Fi Alliance to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications.

The typical Wi-Fi setup contains one or more Access Points (APs) and one or more clients. An AP broadcasts its SSID (Service Set Identifier, "Network name") via packets that are called beacons, which are broadcast every 100 ms. The beacons are transmitted at 1 Mbit/s, and are of relatively short duration and therefore do not have a significant influence on performance. Since 1 Mbit/s is the lowest rate of Wi-Fi it assures that the client who receives the beacon can communicate at least 1 Mbit/s.

The term "Wi-Fi" itself is really a moniker cast by the Wi-Fi Alliance, a group which certifies equipment as being fully standards-compliant and interoperable between manufacturers. All of Hautspot's hardware is indeed Wi-Fi Certified, and Hautspot is a member of Wi-Fi Zone, the provider counterpart to the manufacturer's Wi-Fi Alliance.
