The Wireless Spread Spectrum Network Bridge Technology And Its Application

Spread Spectrum Communication is an important direction of development as modern communication.Spread Spectrum Communication was pay attention to people,such as the good ability of ant-disturbance,the low rate of obstruction,the good ability of multi-address,the good capability of secrecy etc.With the rapid development of society,spread spectrum technology has been rapidly applied to some microelectronic technology,large-scale,ultra large scale integrated circuit technology.This has promoted the growth of spread spectrum communication to a new level.The thesis involved field include Wireless Spread Spectrum,WLAN(Wireless Local Area Network),Network Bridge,Diagram Communication and so on.The thesis briefly describes the definition and theoretical basis,main performance indicators,main characteristics,working principles and working methods of Spread Spectrum technology.And introduce the general situation of DS(Direct Sequence Spread Spectrum),the constitution of system,the assay of capability,the feature and purpose;The correlation reception of DS and the synchronization of DS.The characteristics,physical composition,application,architecture and security of WLAN are briefly introduced.The definition,type,protocol structure,path selection,function and workingprinciple of the network bridge are introduced and this paper introduces the spread spectrumwireless network bridge Western Multiplex 3185C-42.Abriefintroduction to Diagram Communication.Base on the context,expound the apply of spread spectrumwireless network bridge in actuality system.The application of the wireless network bridge in the home and abroad is divided into three aspects: the first is in the large campus or the factory area;the second is the different branch units that connect the nearest urban area and the township;the third is in the temporary need to use the network to carry on the network transmission.The thesis introduces the application of the spread spectrum wireless network bridge in the project: the campus network monitoring solution and the application scheme of the wireless network monitoring system for the famous historic sites;meanwhile introducea communication system for transmitting diagram,data and language signals by Western Multiplex 3185C-42 in the lab.In particular,the joint application of the Interior of Plane Communication Equipment by Shaanxi Fenghuo Electronics Co.,Ltd Intercom Department is described in detail: the structure plan of using Western Multiplex 3185C-42 in the training room is given,and the functions and functions of each device are explained in detail.
