Access points and Network interface cards are two basic components of Wireless Local Area Network. The stationary nodes are called Access Point which concerns with coordination of communication between the nodes and exchanges the information by means of the antenna in the Wireless Local Area Network. In a Wireless Local Area Network, Access Points can transmit and receive data. A Network Interface card scans available frequency spectrum from the environment and normally connects a wireless station to the access point in the Wireless LAN.<\/p>\n<h5><strong>Wireless Local Area Network can be categorized into three types-<\/strong><\/h5>\n<h6><span style=\"text-decoration: underline;\"><strong>I<\/strong><strong>nfrared\u00a0\u00a0Local Area Networks<\/strong><\/span><strong> (I<\/strong><span style=\"text-decoration: underline;\"><strong>R-LAN)<\/strong><\/span><strong>&#8211;<\/strong>\u00a0These type of LANs\u00a0are basically used at home for various remote control devices. IR LANs are such type of Wireless LANs that are bounded in a single room as it cannot penetrate the opaque walls. Infrared\u00a0\u00a0Local Area Networks are inexpensive and simple to design.<\/h6>\n<h6><span style=\"text-decoration: underline;\"><strong>Spread Spectrum Local Area Networks(SSLAN)<\/strong><\/span>&#8211; Spread Spectrum Local Area Networks(SSLAN) operates in ISM (Industrial, Scientific, and Medical) bands whose topology can be either hub or peer to peer. The major function of hub is automatic hand off of mobile stations where FCC licensing is not required.<\/h6>\n<p><span style=\"text-decoration: underline;\"><strong>Narrow-band microwave<\/strong><\/span>&#8211; In Narrow band microwave LAN where frequencies cannot be used as it operates on microwave. These type of Wireless Local Area Networks need FCC licensing for some products.<\/p>\n<h5><strong>Advantages Of Wireless Local Area Network<\/strong><\/h5>\n<ul>\n<li>Flexibility and mobility is greater advantage of\u00a0Wireless Local Area Network.<\/li>\n<li>Wireless Local Area Networks are very easy to install because there is no need of cable or wire connection.<\/li>\n<li>Portability is another advantage of\u00a0Wireless Local Area Network.<\/li>\n<li>Maintenance cost is less.
