Introduction

Wired LAN

A group of PCs connect to a Switch or Hub through Ethernet cables.

Data is transmitted over individual cables hence is more secure.

Each client needs a Network card to connect.

100Mbps of dedicated bandwidth to individual desktops.

Primary Network Technology

Features & Benefits: Benefits for Users and Administrators

Mobility Roaming without Disconnection More than 1 AP provides signals to a single client When signal in use degrades, client tries to find another AP

and gets associated with it. Flexibility

Change the LAN Layout anytime No Ethernet cables

Scalability Add work spaces when required

Manageability SNMP based Network Management tools Web Browser Command Line Interface (CLI)
