Cyber cafe, cafeteria and shopping malls make profitable business with WLAN. Several wireless network business and projects are being installed in the major cities of the world.
The idea of WLAN began with the various researches carried out in the University of Hawaii in 1970. Wireless data modems of first generation were developed in the early 1980's by some local radio operators. A voice band data communication modem was incorporated with the data rates those below 9600 bit/s. Wireless modems of second generation were developed by the use of spread spectrum technology. The data rates of these modems recorded hundreds of kilobit/s. Generation three wireless modem contained data rates Mega bit/s.
The technology of WLAN improvised in the late nineties. Wireless chips were used utility sectors, stock exchanges, educational organizations and corporate sectors. WLAN
became commercially popular with the launch of airport at the Macworld Expo in New York City. WLAN hardware was very costly, it was used where cabled LAN networking was not possible.
Nowadays WLAN or Wireless Local Area Network is launched everywhere from corporate sectors to the utility domains nowadays due to its cost friendliness and convenience of connecting with other networks and network devices. Various computers brands available today come equipped with wireless LAN technology.
WLAN enables users to access network data from any location within the networking environment. WLAN is very effective in laptop-style computers. The public wireless network, enables access of Internet outside the work environment. A connection to the wireless network helps in staying connected in any place in any time. This is very beneficial in fussiness as the employees can produce more work through the access of Internet from any location. With wireless networks miscellaneous clients are provided network from a single equipment at a specific time. Though installation of WLAN requires huge initial cost but the cost is balanced by the huge cost and labor its saves after its installation.
The architecture of WLAN or Wireless Local Area Network has several units like stations, access points, clients, basic service net, distribution system and bridge.
The devices that can connect a wireless medium into network are known as stations. The stations have wireless network interface cards (WNICs). There are two types of wireless stations namely access points and clients. Access points (APs) are major stations for wireless networking. They receive and transfer radio frequencies to communicate with wireless enabled devices. Wireless clients may refer to various mobile sets , laptops, headsets, IP phones and devices with wireless network interface.
