Basic Concepts WLAN

Wireless LAN technology become very popular in many current application. After the evaluation of the technology are made, making users feel satisfied and convinced realiability this technology and is ready to be used in large scale and complex in the network without cables.

Wireless LAN work using radio waves. The radio signal propagates from the sender to the recipient through free space, reflection, diffraction, Line of Sight and Obstructed LOS. This means that radio signals arrive at the receiver through many channels (Multipath), where each signal (on the path that is different) have a level of power, delay and phase different.

This technology was initially designed for application in the office room, but now the Wireless LAN network can be used in peer to peer in the room and also point to point outside the room and point to multipoint applications on the bridge.

Wireless LAN is modular in design and flexible. This network can also optimize the environment in different ways. Can overcome geographic constraints and the complexity of the installation of the cable.
