IT 241 Week 5 Site Survey Benefits

In this scenario, you play the role of a network administrator. Your manager has just

advised you that she wants a wireless network installed in the office, but her timeline for

installation is short, which makes it difficult to conduct a site survey. You know a site

survey is critical before setting up a wireless network, so you must persuade your

manager to adjust the timeline to allow for one.

Resource: Ch. 15 of CWNA Certified Wireless Network Administrator Official Study

Guide

Write a 1-page memo persuading your manager to allocate the time, money, and other

resources necessary to conduct a site survey. Use memo format such as the MS Word

memo template to complete your assignment.

Include the following points:

The benefits of conducting a site survey

The possible repercussions of not conducting a site survey

The tools you need to conduct the site survey as well as a rationale for each tool

IT 241 Week 5 Floor Plan Site Survey

Site surveys allow you to place access points in locations that provide an optimum signal

without resorting to trial and error.

Conducting a site survey is a critical component of properly designing and installing a

wireless LAN. Every building is unique; therefore, a network consultant should always do

a thorough walkthrough to analyze signal strength and to identify any objects that might

cause interference.

In this assignment, you will analyze five office floor plans. The data you gather will assist

you in completing your final project. As you analyze each plan, consider what objects or

materials affect the signal strength, why they do so, and what you can do to overcome

their interference.


Guide;

Analyze the five floor plans in the Floor Plan Site Survey exercise located on the student

website. Each plan has only one access point placed in the data center of each building.

The location of the data center may not always be ideal for optimum signal coverage, so

you will use this survey to determine where to place other access points as needed.

Complete Appendix E.



IT 241 Week 6 Placing Access Points

All wireless access points emit wireless signals in a set range. When designing a wireless

network, you must consider these ranges to ensure proper signal strength and coverage.


Guide

Position the access points in Appendix F in the proper locations on the floor plan to

provide a strong, continuous signal to the entire floor.

IT 241 Week 8 Wireless Security

The old adage "Where there's a will, there's a way" holds true in the world of wireless

technologies. If a person has the will to break into your network, he or she will attempt to

do so in every possible way. This assignment provides an opportunity for you to explore

the various vulnerabilities of wireless networks.

Resource: Appendix G, Ch. 11, 13, & 14 of CWNA Certified Wireless Network

Administrator Official Study Guide

Address the following questions in 1 page:

Some attackers intend to cause harm to the network they are attacking, while

others do not have a malicious intent. Of the following six categories of attackers,

which category would you want to break into your network? Why?

Hackers

Crackers

Script kiddies

Spies

Employees

Cyberterrorists

Of the three categories of wireless security protection (MAC filtering, WEP, and

IT 241 Week 9 Planning a Wireless LAN

In the final project, you assume the role of a wireless network consultant working for a

company named Apex Designs. You helped the company determine that installing a

wireless network in five of their office buildings would be cost-effective and beneficial.

The company wants each of its 345 employees to connect their laptops to the wireless

network anywhere within the five buildings. Your task is to present Apex Designs with a

plan that outlines how you intend to design their wireless network.

This assignment asks you to develop a wireless network design plan for one of Apex

Designs’ buildings. Complete the recommended steps for designing a wireless LAN and

create a wireless security policy. Apex Designs has already completed some of the plan’s

components, but you must complete the remaining elements.

Resources: Appendix A; CWNA Certified Wireless Network Administrator Official Study

Guide

Select one of the five floor plans in Appendix I. Use the data gathered in the Floor Plan

Site Survey assignment to determine the floor plan you want to use in your final project.

You will use this floor plan throughout your final project.

Use the template in Appendix J to compile the following components of your wireless

network plan:

Deployment Scenario

o Determine the correct deployment scenario for your network.

o Provide a rationale for the scenario you selected.

o Identify the hardware components your wireless network will utilize. You

may select components from the Wireless Network Components

assignment.

o Provide a rationale for how you will use each component in your network.

o Estimate the approximate cost of each component in your network.

IEEE Wireless Network Type: Apex Designs has indicated that an 802.11n LAN

will be implemented.

Access Point Management: Apex Designs will use thin access points to simplify

the management of the wireless LAN. Thin access points allow managing the

wireless network from one central location rather than to be configured separately

for each access point.

Location of Wireless Devices

o Develop a network performance impediment report using the data from

the Floor Plan Site Survey assignment. The report must discuss any

impediments to network performance located in the floor plan you

selected.

o Include large items such as filing cabinets, concrete walls, or other objects

that might interfere with the performance of your wireless network.

o Use Appendix I to place access points and switches in the proper

locations on your floor plan. You must provide a strong, continuous signal

to the entire floor.

o Draw the necessary network cables between access points and switches

using the drawing tools in Microsoft® Word.

Wireless Security Policy

o Identify the types of security your wireless network will implement. Your

security policy must include at least two of the security protections listed in

Ch. 13 ofCWNA Certified Wireless Network Administrator Official Study

Guide.

o Write a one-half-page summary for each protection and include an

explanation of why you selected it.

o List the vulnerabilities of each protection you selected.

Format references and in-text citations consistent with APA guidelines.

Post Appendices I and J as separate Microsoft® Word attachments.
