What Is WiFi Internet Access?

Wi-Fi is wireless networking technology that allows a device to access the Internet without direct wired connection to a modem. Almost all computers built have Wi-Fi Internet adapters included in them, and many other devices, such as phones and portable gaming devices, also have Wi-Fi built in.

Components

Wi-Fi must have specific components in order to be classifed as Wi-Fi by the Institute of Electrical and Electronics Engineers. These components must fit under one of the IEEE's 802.11 guidelines, such as the 802.11a, which requires a 5GHz band to transfer data at a speed up to 54 Mbps

Hotspots

A "Wi-Fi hotspot" is a public location where individuals can access the Internet using their wireless signal. Wi-Fi hotspots can either charge or offer their Internet access for free. Common Wi-Fi hotspots include coffee shops, airports and libraries.

Router and Modem

Wi-Fi Internet access still requires that there be a stable Internet signal, and thus a router hooked up to a modem is still required for the Internet to be accessed.

Bluetooth

Bluetooth is an alternative form of Internet access and is not a form of Wi-Fi. Bluetooh regulations fall under IEEE protocol 802.15.1.

Trademark

The name "Wi-Fi" was developed by the IEEE, but was trademarked by the Wi-Fi Alliance.
