The hottest technology in personal computing is wireless networking, which allows users to share a high –speed Internet connection among multiple computers without being tethered to wires or wall jacks. Known as WI-FI, this wireless system is commonly used to connect computers in various rooms of a home, but it’s also popping up in public houses like airports, hotel lobbies and coffee shops.

The Mobile Internet relies on a new set of standards, known as the Wireless Application Protocol (WAP). The existing technology will provide efficient access to information and services from a wide range of mobile devices. In particular, WAP extends the Internet by addressing the unique requirements of the wireless network environment and the unique characteristics of the small handheld devices.


Imagine connecting to our office network from an airport or coffee shop. or retrieving files or presentations from the corporate network, cruising the Internet ,or sending instant messages to co-workers while sitting in a conference room or the company’s cafeteria .And that too easily and quickly ,without worrying about finding a wired network connection .That is Wi-Fi.

Wi-Fi, or Wireless fidelity ,is freedom: it allows you to connect to the Internet from your couch at home, a bed in a hotel room ,or a conference room at work without wires. It is a wireless technology like CELL PHONES .Wi-Fi enabled computers send and receive data indoors and outdoors anywhere within in the range of a base station . And the best thing of all ,Wi-Fi is FAST. In fact ,it’s several times faster than the fastest cable modem connection.

However , we only have true freedom to be connected anywhere if our computer is configured with a Wi-Fi certifies radio(a PC card or similar device).Wi-Fi certification means that we will be able to connect anywhere with other Wi-Fi certified products ,in areas equipped with Wi-Fi access.
