Wireless technology is a famous source of networking for different technologies of computer networking of present era. Wireless network which is commonly called as WiFi, is a type of that technology in which radio signals of high frequency are used to transmit data from one device to another. It only operates on several hundred feet.
Wireless LAN or WiFi is divided into three main parts on which its whole working depends and all of its applications also depend on these parts. These types are as follows;
- Infra structure mode.
- Ad hoc network mode
- Mixed network mode.
Infra structure Mode:
Any kind of machine that can communicate with every type of work station of wireless LAN or WiFi with the help of access points is called as infra structure network mode.
Ad hoc Network Mode:
A type of network in which all the work stations are linked together with other work stations without any obstacle is referred to as ad hoc network mode.
Mixed network mode:
It is form of network which is developed by mixing infra structure and ad hoc network and the work stations can work simultaneously in it, is known as mixed network mode.
How it Works?
Basically the working of WiFi is based on transmission process. In this process the data which is going to be transferred has to be transmitted in the form of radio signals, and then the device transmits these signals to antenna which is used for transferring of data. This antenna is which is used for transmission purpose is connected with a wired LAN or DSL. A router is also connected with the device which is able to receive the signals and also help in decoding them. Then this information is spread on internet.
Wireless LAN Architecture:
The process of assembling the parts of computer hardware in computer networking is called as computer architecture. Similarly if we use this architectural technique in Wireless LAN or WiFi is called as Wireless LAN Architecture. It is a technique of designing and arrangement of different components in Wireless local area networking device in a specific way. Special type of device which is the combination of transmitter and receiver called d as transceiver which is an essential part for standard Wireless LAN architecture that is known as Access points.
Components of Wireless Architecture:
Wireless LAN architecture is composed of different components which help in establishing the local area network between different operating systems. These components are very essential for WiFi architecture.
- Access point
A special type of routing device that is used to transmit the data between wired and wireless networking device is called as AP. It is often connected with the help of wired devices such as Ethernet. It only transmits or transfers the data between wireless LAN and wired network by using infra structure mode of network. One access point can only support a small group of networks and works more efficiently. It is operated less than hundred feet. It is denoted by AP.
Any kind of device such as personal computers, Note books, or any kind of mobile devices which are inter linked with wireless network area referred as a client of wireless LAN architecture.
A special type of connectors which is used to establish connections between wired network devices such as Ethernet and different wireless networks such as wireless LAN. It is called as bridge. It acts as a point of control in wireless LAN architecture.
Two components are also some time play an important role in Wireless LAN architecture i.e.
- Basic Service Set (BSS)
- Extended Service Set (ESS)
