Wireless LAN,As the name suggests is a wireless technology replaces the use of cable wiring methods constitute a new means of LAN that can Provides all the features of the traditional wired LAN. It is the computer network and wireless communication technology product of the combination,system with a subset of access. In principle, there are similarities with the Bluetooth. Compared with the Bluetooth, It can support a higher transmission rate(2~54Mbit/s Or more). Use radio frequency radio or infrared achieve a fixed, semi-mobile network terminal on the Intemet network high-speed connection to access more remote. Therefore, in principle, with lower rates of Bluetooth technology has different market positioning, complement and support each other to form a complete and effective WLAN Wireless Access. Wireless network in remote access mobile access and temporary access in all the great advantages of unmatched, With the wireless network equipment prices for common people, the practical application of the wireless network also more and more.
This article describes how to build a WLAN indoor signal distribution systems and the need to use the related software and device. AutoCAD for mapping coverage of the plan required, Visio for drawing the point system plan, This design was complete, three-dimensional, two plans are essential. There are devices for use by AP, switches and other active equipment as well as by the line, antenna, power divider, coupler composed of passive components such as antenna and feeding system.
