Term: wifi

Wifi, or more correctly Wi-Fi,  is a wireless radio signalling protocol that defines a way for data – typically ethernet data packets – to be transmitted wirelessly between devices.

We tend to think of Wi-Fi primarily as a means for connecting a computer with a Wi-Fi adapter to a network by means of a Wi-Fi access point, often included as part of a wireless router, connected to the internet.

Wi-Fi refers to specific standards, typically a variation of 802.11 a, b, g, or n.

Most consumer-grade Wi-Fi equipment has a range of a few hundred feet, and thus Wi-Fi is considered a short-distance signalling protocol.
