Scenario
Scenario Summary


A Fortune 500 Company has recently hired you as a Human Resource Manager. You are in charge of hiring new sales consultants for the fiber optics division of this organization. Due to the competitive marketplace, sales and revenues are at an all-time low. During your interview, you stated that you could serve as a valuable asset to this company. You noted your long-standing history of selecting the best candidates for sales positions and stated that you could bring the sales division back to its place as the leading resource of your organization. You want to perform well at this job because you have been unemployed for 12 months and need to pay off your consolidated debt in order to avoid bankruptcy.

Your Role

Your job is to hire a sales manager to sell your latest fiber optics to leading wireless manufacturers of five key companies. This job requires that the sales representative be articulate, sophisticated, and knowledgeable about fiber optics. The job requires travel Monday through Friday in order for the sales representative to work with those in the prospective company. This job also includes spending leisure time after 5:00 P.M. with prospective clients.

Your Assignment


Required: Read the case summary and accompanying character descriptions, then answer the following question:

Who would you hire for this position and why?

Essay Instructions: Answer the two questions::: (1) Why should "overhead" in an organization's network concern a manager? (2) What are the key security issues in using various guided and unguided media?

Transmission Media
These are the types of guided and unguided media.
• Guided
o Twisted Pair
o Coaxial
o Fiber Optic
• Unguided
o Terrestrial microwave
o Satellite microwave
o Radio
o Infrared

Guided media can use a large span of frequencies across the frequency spectrum. It is important to see the relationship of the various media. As you go higher in the spectrum of frequencies, you get more bandwidth. As you probably know already, 108 is 10 times larger than 107, so looking at the 1014 or 1015 range looks pretty big in terms of bandwidth and data rate. Looking at this, you should be able to see why fiber optics can carry so much data.

For unguided media, transmission and reception are achieved by means of an antenna. There are basically two types of configuration for wireless transmission: directional and omnidirectional. For directional configuration, the transmitting antenna puts out a focused electromagnetic beam that will be received by the receiving antenna. The transmitting and receiving antennas must therefore be carefully aligned. In the omnidirectional case, the transmitted signals spread out in all directions and can be received by many antennas.

Advantages
• Covers greater distances without installing cable
• Communicate where cable can't go (space, swamps, mountains, oceans, etc.)
• Can go through buildings and obstacles with some frequencies
• Can support mobile transmitters and receivers (except in terrestrial microwave and some satellite systems)
Disadvantages
• More noise
• Can be hard to set up (microwave and satellite)
• Share the airwaves. A specific frequency or set of frequencies are required to legally operate.
