Local Area Network or LAN is commonly used in colleges, universities and small organizations. It is mainly used for connecting the computers in a Local Area Network. It simply facilitates easier and faster sharing of information. This task becomes extensively useful if we go for wireless LAN. There is no need to bother about jumble of wires. There will be no more wires to make problems or stop you from accomplishing your intended task from a different location. Let us look at how Wireless LAN works.

If you are interested in connecting few laptops inside a restricted range that will form a network, then wireless LAN can be the best option for you. Nowadays, many laptops have inbuilt wireless network feature. Therefore, it may be a simple task for connecting all the laptops in a LAN. What you need to do is, follow all the steps in the wireless network connection wizard properly. This will help you to form your own network. This will facilitate other laptop users to join your network, too. In addition to this, you are able to form wireless LAN by connecting more than one desktop computer. For this, you will require a ...

Now, many of us will think how can a wireless LAN work, in the absence of medium for the transfer of data. Let us look at the technical perspective of this doubt. First, we will see Wireless LAN Protocol and its function. A protocol is a set of rules, which determine the execution, or performance of a particular task. For communication, set of rules will decide the way in which the information is received and transferred. In addition to this, it determines the bandwidth and speed that can be permitted for the flow of data. Ethernet LAN standard is utilized for a wired LAN structure. However, this kind of structure was not adequate for the wireless Local Area Network.

This is because there is no any fixed medium present for the transfer of data. There was need of additional information for the transmission of the frames or packets of data. IEEE 802.11g standards are utilized for wireless LAN. Earlier there was use of IEEE 802.11b standards. 802.11b is capable to work at speeds of 10-12Mbps whereas 802.11g standard can work with a speed of about 56Mbps. In addition to this 802.11g standard also facilitates the working at 2.4GHz frequency.

Two basic layers for the reception and transmission of data are defined by 802.11 standard. They are the MAC (Media Access Control) layer and the physical layer. Like other networks, the data in wireless Local Area Network is transferred in the form of frames. The 802.11 structure permits the numerous client machines to be connected in a Local Area Network for accomplishing communication at multiple data rates. Wireless LAN facilitates easier and faster communication. If you intend to know more about this or implement wireless network at your home or office, then Save My System can help you out.
