Lecture Basic network management: Chapter 16 - Wireless LAN. Chương này cung cấp các khái niệm về wireless; các mode sử dụng trong hệ thống mạng Wireless LAN; thế nào là ad-hoc mode? Infrastructure mode?; Các tiêu chuẩn IEEE , , . | Chapter 16: Wireless LAN Objective What is Wireless LAN? What is infrastructure Mode? What is ad-hoc mode? IEEE -Chương này cung cấp các khái niệm về wireless? -Các mode sử dụng trong hệ thống mạng Wireless LAN -Thế nào là ad-hoc mode? Infrastructure Mode? -Các tiêu chuẩn IEEE , , WireLess Lan Wireless Lan connect the computers and network communication devices within geographically limited areas. WireLess Lan use frequency band 2,4Ghz Wireless Lan WireLess Lan does not require: Lining-up Line of sight Wireless Lan WireLess Lan has many advantages in connecting the devices together in your office. Fast deployment. Easy installation,easy and convenient to operate. Easy upgarde and maintenance. Network access everywhere,everytime. Wireless Lan IEEE : Defined network standards for physical components of wireless Lan IEEE : built in 1997 Wireless Lan IEEE has two modes: Infrastructure mode Ad-hoc mode Wireless Lan Infrastructure mode: Wireless Lan use Access-point And computers with wireless Card are connected together through Access Point Wireless Lan Ad-hoc mode: Devices which can connect together directly Without Access point Wireless Lan IEEE : Wireless Lan Speed: 1Mbps – 11Mbps Frequency Band : 2,4 Ghz ISM Band(Insdustrial Scientific Medical Band) Wireless Lan IEEE Plus (IEEE +) Improved from IEEE b Frequence band : 2,4Ghz DSSS Speed :22 Mbps Wireless Lan IEEE a: Wireless Lan.
