A way to get Internet access, the term Wi Fi is a play upon the decades-old term HiFi that describes the type of output generated by quality musical hardware, Wi Fi stands for Wireless Fidelity and is used to define any of the wireless technology in the IEEE 802.11 specification - including (but not necessarily limited to) the wireless protocols 802.11a, 802.11b, and 802.11g. The Wi-Fi Alliance is the body responsible for promoting the term and its association with various wireless technology standards.

WiFi is called Wireless Fidelity, or Wireless internet. In most areas, there are many wifi providers to choose from! The best part is- they're all free! You can choose from "Joe's WiFi", Linksys, Netgear, or sometimes Holiday Inn. You'll probably get the best experience with linksys or netgear, because the idiots that rename their router probably aren't smart enough to lock it.

No contracts, no obligations, no credit card required!
WiFi! It's the wave of the future!
Mike: Hey neighbor, you got WiFi? Mine went down!

Mike: Joe's WiFi.
Joe: WHY YOU SON OF A $^#@$
