  1. Exam date has been decided - see below
  2. Assignment 3 is now posted below
  3. Check your quiz and homework marks - Warning grades as well
  4. At the request of some students - here is a sample matlab simulation code for cdma2000 (1xRTT) that you can use a demo. The code is copy right protected and is provided as a demo only. Expand the zipfile in a local directory and call the routine "input2" from the matlab prompt to execute the demo code. (note the code is available only on the intranet)
  5. You can check your quiz marks, homework marks,  and exam marks here. For grades click here.
  6. Matlab code to aid for some simulation projects - Produced by the authors of "Wireless Communications and Networking", Jon W. Mark, University of Waterloo and Weihua Zhuang, University of Waterloo.


Term Projects:

The topics and policy is explained the following power-point package. Please try to finalize the team/project selection by Tuesday March 11th, 2003 (Note the date change). Note that the term project now carries 25%. The final project assignment is shown in this excel sheet

Notes for Term Project:

The material presented as a term project should be obtained/authored/analyzed this term (Feb-June 03) and for this course COE543

You can not use this term project for other courses you are taking this semester, especially for COE560 or visa versa.


Exam Dates:

Exam dates are:

Lecture Notes

Students are responsible for the material in the references and that in the papers/handouts, if any. The class notes and slides are just "notes"; they may not cover all required material. The instructor will point out the required chapters in the reference books and papers.

As the semester progresses, I will be depositing electronic copies of  my class notes as they become available on this page. My notes are based on the references. Please be advised that online notes are subject to change as courses develops.

1) Introduction to Mobile and Wireless Networks: An overview of 1G, 2G, mobile data services, and WLANs. In addition to an introduction into 3G and beyond 3G networks. A must read references are:

2) RF Propagation - The main sources for this subject are:


3) The Cellular Concept: cellular network fundamentals - capacity expansion techniques.

4) Multiple Access Schemes: FDMA, TDMA, CDMA, and Contention-based schemes

5) Example of a TDMA network - GSM

6) Example of a CDMA network - IS-95 and cdma2000

7) Review material for midterm exam

8) Wireless Local Area Networks - IEEE802.11

9) Mobile IP:

10) Privacy and Security for Wireless Networks - Notes





Assignment 1: Tuesday Feb 25, 2003 - Due date Tuesday March 11, 2003

Summarize, using your own words and in not more than one page for each, the following two papers:

  1. G. H. Forman, J. Zahorjan, "The Challenges of Mobile Computing," IEEE Computer, V 27, N 4, (April 1994), pp. 38-47
  2. D.J. Goodman, “The Wireless Internet: Promises and Challenges”, Computer, Vol. 33, No. 7, pp.36-41, July 2000.

Assignment 2a: Sunday March 16th, 2003 - Due date Sunday March 23rd, 2003 - solution

    Chapter 2: “Principles of Wireless Networks – A Unified Approach,” Kaveh Pahlavan and Prashant Krishnamurthy - Problems: 2.5, 2.7, 2.9, and 2.11

Hints (based on the questions I receive):

  1. For 2.5 - the breakpoint distance formula given in slides gives the distance in kilometers.

Assignment 2b: Reading Chapter 3 from Pahlavan's book -"Physical Layer Alternatives for Wireless Networks," - An introductory tutorials for digital communication is found at:  and (I tested this second link on my machine - it works fine!!)

There is no deliverable for Assignment 2b - However there is a quiz on the subject - refer to Quizes and Major Exams section.


Assignment 3: Tuesday April 1st, 2003 - Due date Tuesday April 8th, 2003  - solution

    Chapter 2: “Principles of Wireless Networks – A Unified Approach,” Kaveh Pahlavan and Prashant Krishnamurthy - Problems: 5.2, 5.4, and 5.5

Hints (based on the questions I receive):

  1. For problem 5.5 part c, you will need the CDMA capacity equation in Chapter 4 of Pahlavan's book

Assignment 4: Sunday May 4th, 2003 - Due date Sunday 25th, 2003 

    Chapter 2: “Principles of Wireless Networks – A Unified Approach,” Kaveh Pahlavan and Prashant Krishnamurthy

     - Problems: 7.1, 7.2,   8.5, 11.4 - solution


Quizes and Major Exams:

Check Your Status:

         Note: Compare your answers with the key solution posted above. The exam is made exceptional simple; in addition I have been         exceptionally generous in marking it - If you got a mark below 40 (i.e. less than 50%), I think you should reconsider your situation and please come to talk to me.
