Wi-Fi allows local area networks

Wi-Fi allows local area networks (LANs) to be deployed without wires for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs.

Wireless network adapters are now built into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in even more devices. Wi-Fi has become widespread in corporate infrastructures.

There are a number of reasons for a company to implement wireless networking.
Wi-Fi makes it much easier for workers to connect to the LAN from their laptops in conference rooms, break rooms and other areas that may not have wired Ethernet jacks, or may not have enough for the number of people present.

A wireless network also provides a way to allow visitors to access the Internet with their laptops or handhelds--for example, to check their e-mail.

Rolling out a wireless LAN within your organization, however, is more complicated than just plugging in a wireless access point (WAP). You need to address a number of factors in the planning stage to ensure both accessibility and security. Here are some of the things you should consider as you prepare to go wireless.

Spectrum assignments and operational limitations are not consistent worldwide. Most of Europe allows for an additional 2 channels beyond those permitted in the U.S. for the 2.4 GHz band.Japan has one more on top of that. Europe, as of 2007, was essentially homogeneous in this respect.
