A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. Universys gives users the mobility to move around within a broad coverage area and still be connected to the network.

For the home user, wireless has become popular due to ease of installation, and location freedom with the gaining popularity of laptops. Public businesses such as coffee shops or shopping malls have begun to offer wireless access to their customers; some are even provided as a free service. Large wireless network projects are being put up in many major cities.

The benefits of wireless LANs

•  Convenience: The wireless nature of such networks allows users to access network resources from nearly any convenient location within their primary networking environment (home or office). With the increasing saturation of laptop-style computers, this is particularly relevant.
  
  
•  Mobility: With the emergence of public wireless networks, users can access the internet even outside their normal work environment. for example, offer their customers a wireless connection to the internet at little or no cost.
  
  
•  Productivity: Users connected to a wireless network can maintain a nearly constant affiliation with their desired network as they move from place to place. For a business, this implies that an employee can potentially be more productive as his or her work can be accomplished from any convenient location.
