Outline What is Wireless LAN? How it works? Advantages of using wireless Network. Disadvantages of using wireless Network. Particular uses of wireless Network. Building the wireless workplace.

What is Wireless LAN? What is Wireless LAN? It is a type of computer networks, using radio waves as a career to send and receive information .

How it works? How it works? Transmitters broadcast towers. Radio waves. Router receive. Cards.

Benefits of wireless Network 1) Installation speed and simplicity. No cable to pull Few transmitters and receivers for multiple users 2) Installation flexibility. It goes where wires can not Easy to add more computers and devices

Benefits of wireless Network 3) Reduced cost of ownership. - No need to build wiring closets 4) Mobility. Provides services opportunities Promotes flexibility Supports productivity

Benefits of wireless Network 5) Scalability. Works over great distance Effective for wide range of user communities Configurations are easily changed

Disadvantages of using wireless Network Cost Wireless cards cost 4 times more than wired network cards Access points are more expensive than wires Environmental Conditions Constrained by buildings and trees Susceptible to weather and solar activity

Disadvantages Less capacity Slower bandwidth Limit to how much data a carrier wave can transmit without lost packets impacting performance

Particular uses of wireless Network Practical uses Particular uses of wireless Network Corporate Mobile networking for e-mail File sharing Web browsing Finance Facilities electronic payments for goods and services improve the speed and quality of trades

Manufacturing Practical uses Tracking of goods Remote data collections. Tracking of goods Link factory workstations to servers

Building the wireless workplace • How to configure a wireless LANs: 1) Peer to peer Network 2) Clines and access point 3) Multiple access Points and roaming 4) Using an extension point 5) Using a directional antenna
