The performance of Wireless Local Area Network (WLAN) is highly dependent on the processes that are implemented in Medium Access Control (MAC) sublayer regulated by IEEE 802.11 standard. In turn, various parameters affect MAC sublayer, most important which number stations network and offered load. With massive growth multimedia traffic, research depending traffic types relevant. this paper, we ...

Visually-assisted optical indoor wireless local area network (LAN) is promising not only for high-speed but for offering intuitive user interface. Free-space optical communications (FSOC)(Jahns, 1994) are a key technology to create image-based ultra-fast wireless communication systems of the future. Compared with radio-frequency (RF) electromagnetic waves, the outstanding features of free-space...

Wireless technology has many practical applications in business and society. Its mobility allows users to access information any time and from any location. Because users depend on network connections for their personal computers, wireless local area networks (LANs) offer a convenient and cost-effective solution for providing those connections. The continuing development of wireless technology ...

mobility and portability with high-bandwidth data, voice, and video access. This has led to the introduction of wireless LAN technologies, which attempt to provide exactly that. In the 2.4 GHz frequency band, IEEE 802.11b is “the” wireless LAN solution in the market. However the 5 GHz frequency has two possible contending technologies — IEEE 802.11a and HiperLAN2. This white paper explains the ...

By definition, IEEE 802.11 wireless LANS (WLANs) are constantly in flux. There is no way to predict where a particular client will be at any moment, making it equally impossible to predetermine the load on any wireless access point (AP). How will 802.11 Wi-Fi networks running in adjoining offices or on different floors affect one another? Even something as seemingly trivial as rearranging cubic...

The domain of wireless Local Area Networks (WLANs) is growing speedily as a consequence of developments in digital communications technology. The early adopters of this technology have mainly been vertical application that places a premium on the mobility offered by such systems. Examples of these types of applications consist of stocking control in depot environments, point of sale terminals, ...
