CprE 537X Wireless Network Security Study Guide for the Midterm ...

CprE 537X Wireless Network SecurityStudy Guide for the Midterm ExamThe exam will be open book and open notes.You should organize your notes and make an index of them so you can quickly find informationin them.The exam will be made up questions from the following lecture material and example questions.If you know all of this material, you will write a perfect exam. The purpose of giving a studyguide and exam in this format is to have you study the question list and develop your ownanswers. Therefore, the answers to these questions will not be provided. Be sure to read ourbook and look up answers on the web.There will be a mix of problem types on the exam. Some will be essay and some quantitative.Draw figures where they are needed. Be sure to describe your solution in detail so I can givepartial credit.Some material may be duplicated in different lectures.Lecture Outline for Midterm Exam# Jan 9, 2006* Write a definition of a radio terminal?# Jan 11, 2006* Describe the functions of a mobile switching center.* Draw a simple diagram of a wireless network connected to a wire or fiber infrastructure.# Jan 13, 2006* What are the four classifications of communication security systems?
