Case Description
The organization you work for has
leased a building next door to the existing building. The local area networks
in the new building and the existing building must be linked to each other. The
distance is 657 feet. Here is the relationship of the two buildings.
Notice that the blue dashed line
showing the route of the link crosses a parking lot not under your control. It
also crosses a public street. Both buildings are two stories tall. From the
second floor or the roof of each building there is a clear line of sight above
the expected height of any vegetation currently in the area.
You have been assigned the task of
determining the available wireless methods that could be used to connect the
buildings to each other and presenting these options to the executive team. The
executive team consists of the CEO, the CFO, and the managers of the five
business units. They will need to know the following about each option in terms
that nontechnical staff can readily understand:
- The way the method transmits data back and forth
- The advantages of the method
- The disadvantages of the method
- The costs of the method
- Whether the costs are classified as opex or capex
- Whether any permits are required from the controlling
jurisdiction
- Whether there are any legal requirements that must be
meet before deploying it
- The inherent security of the method
- Whether you recommend this method and why or why not
Your assignment it to prepare a
concise presentation that provides the executive team with all of the
information they need to select the best method.
The purpose of this exercise is to
give you experience in communicating technical issues to a nontechnical
audience, researching options to solve a common network problem, and giving an
organized, succinct, and captivating presentation.
Case Grading
The presentation is worth 140
points.
- The PowerPoint presentation is due in Week 5.
- The PowerPoint presentation should be at least 10
slides and must answer satisfactorily all 9 questions listed above.
PREVIEW:
To
determine the best way of connecting the two LANS, I will discuss four methods
of wireless data transmission, such as the Wireless Free Space Optics, the
wireless bridge, the Local Multipoint Distribution System, and the WiMax
Technology. For each of these methods, I will discuss their advantages
and disadvantages, the…
