• Wi-Fi stands for Wireless Fidelity and is, a set of standards for transmitting data from computers etc over a network without wires.
• This transmission is fast enough to allow transfer at a broadband-like rate
• If you are within a certain distance of a WI-Fi transmitter and have the necessary receiver in the device you wish to access it with, then it should be possible. This zone of connectivity is known as a hotspot.
• Many laptops and several phones and portable media players now come with built in Wi-Fi connectivity – as well as next generation consoles like the PlayStation 3
• Home computers and laptops can often be upgraded fairly cheaply to be linked into a Wi-Fi network with a plug in card or gadget.
• Wimax is a next generation version of Wi-Fi. It can integrate into current Wi-Fi technologies but has a much broader range and can send larger amounts of data per second.
