Lab 1.2.7 Networking Media

Estimated Time: 15 Minutes

Number of Team Members: 5 teams with 2 students per team

Objective

The following objectives will be covered in this lab: Identify the basic media characteristics of wireless LANs. Identify the components of a Wireless LAN. Describe the functions of the Wireless components.

Scenario

Wireless Local Area Networks (WLAN) have become a popular choice in network installations.WLAN is simple because installation is generally limited to installing building mounted antennas andplacing the access points.

Local Area Networks (LANs) will quickly become a mixture of wired and wireless systems dependingon the network needs and design constraints.

In larger enterprise networks, the core and distribution layers will continue as wired backbonesystems. Enterprise systems are typically connected by fiber optics and unshielded twisted pair (UTP) cabling. Even in many smaller networks, there still remains a wired LAN at some level.

Preparation

The instructor will need the equipment bundle for the Wireless Networking course. The instructor willallow the students to examine the equipment and be able to compare the equipment to wirednetworking equipment

The following tools and resources will be required to complete the lab:

A conventional PCI and PCMCIA Network Interface Card(s) for wired networking

connections A conventional wired network hub

The Cisco Wireless course equipment bundle

Safety

Do not handle any wireless devices while they are powered. A general rule is to not touch or comewithin several inches of any powered antenna. Also, make sure to power down any device beforeremoving a PC or PCMCIA card. Most important, do not remove antennas from a Wireless AccessPoint or Bridge while powered. This can damage the unit.

Step 1

Hardware PresentationThe instructor will allow the students to physically handle the equipment in the Wireless Networkingcourse bundle.
