Task
1. How does the WiMAX privacy sublayer provide security for a WiMAX network?
2. How does CSMA/CA in DCF handle media contention?
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.
Rationale
To demonstrate your understanding of: wireless networks terminology and technology; planning and performing wireless network site survey; wireless network security; emerging mobile network technologies; research skills;

Quality of the Study Study was done in-depth and the beyond the obvious, revealing new insights gained. Author clearly identified the way of the research approaching by the other researchers and clearly predicts in which way the research would be going in future.
Presentation
Study was in a sufficient depth. Authors identified the research progression, and produce speculation of future research on the topic with lack of confidence. effective in creating imagery Surface study is performed. Author presented mainly description of different research and showed the correlations of the research of the topic. However, the authors failed to speculate the future trends of the research.
Minimal study is performed. The research consists predominantly of information collection, and making simple correlations of different research work on the topic.
