3. Telestra is a company that is
licensed to provide wired telecommunication services in Australia. The company
has contracted Exetel to assist it with the selection and implementation of a
new field service system. The goal is to provide service technicians with wireless
access to the corporate network and a vast electronic library of technical
manuals and schematic diagrams, which would reduce or eliminate the need for
staff to carry a large number of books and drawings, especially while servicing
equipment underground or when climbing on transmission towers. In addition,
this means that the technicians would be able to immediately read and update
the records for all the equipment, thereby avoiding massive amounts of
paperwork as well as potential errors and omissions. However, the company is
having trouble deciding on which technology to adopt- handheld cellular, tables
with 3G or 4G access, or notebooks equipped with cellular cards. Exetel has
asked you to help.
-Create a presentation outlining the
advantages for Telestra of using digital cellular handsets or cellular wireless
cards. Determine the ability of the smaller cellular handsets (as opposed to
notebook computers, which may be difficult to carry everywhere) to display
standard PC documents such as Word, Excel, and PDF files, and evaluate how this
could help the company. Because the group you will be presenting to is composed
of nontechnical manager, be sure your presentation is understandable by both
technical and non-technical personnel. Limit yourself to a maximum of 15 PowerPoint slides. [9 marks]
