Importance of Wi-Fi Technology

Purpose

* The purpose of Wi-Fi is to hide complexity.* Purpose for study.* The main purpose of Wi-Fi are:

1. Faculty/staff, students. 2. Service will be provided for? Laptops, Desktops, cell

phones/PDAs, etc.3. Where users need wireless connectivity? Classrooms, offices,

outdoors, cafeteria, library etc. 4. How many devices need wireless access in each location? Cell-

phones/PDAs, Desktops Classrooms etc.5. Remove switches, adapters, plugs, pins and connectors & wire.

Topologies & Configurations

1. Access Point Based Topology

2. Peer to peer Topology

The client communicates through Access Point.

Access Point Based Topology

Elements of a WI-FI Network

▪ Access Point (AP)- The AP is a wireless LAN transceiver or “base station”

that can connect one or many wireless devices simultaneously to the

Internet.

▪ Wi-Fi cards- They accept the wireless signal. They can be internal and

external.

(e.g. PCMCIA Card for Laptop and PCI Card for Desktop

PC)

▪ Protect networks- Anti-virus software protect networks from uninvited

users and keep information secure.
