Computer Communications - ECE 3600 A

The objective of this course is to study the basic concepts of communication networks, protocols and their performance.  

Students taking this course will have to read material before class, study the homework and/or any exam solutions given out to them, and submit homework on-time. Throughout the duration of the course we will have three quizzes that each would count for the 10% of the final grade. The final exam and the (roughly) biweekly homework will count towards a 35% and 30% of the final grade, respectively. Finally, 5% of the final grade will be determined based on your class participation (Note: Participation is not equal to attendance!).

Prerequisites for this course are elementary calculus, probability and circuits. Attendance is not mandatory but highly recommended.

Course Expectations, Requirements and Policies 

All students must follow the Georgia Tech Honor Code

I. Course requirements

  • Three in class quizzes 
  • Biweekly (roughly) homework
  • One final exam
  • Class participation

II. Grading Scale 

There is no curve in this course. However, we may elect to include extra credit assignments at various times during the semester. The grading breakdown is as follows: NOTE: Grading subject to minor changes. 
  • Quizzes 30%
  • Homeworks 30%
  • Final 35%.
  • Class participation 5%.

III. Letter Grades

Letter grades are given according to the following cutoffs with no rounding:
90.0 <= A <= 100 
80.0 <= B < 90.0 
70.0 <= C < 80.0 
60.0 <= D < 70.0 
0 <= F < 60.0

IV. Appealing Grades 

You have the right to question your grade on any assignment and quiz; but you must initiate discussion about the grade within one week of receiving the grade. All re-grade requests should be sent via email to the TA for your section. In the email, include your T-square id and a clear description of which questions you would like reviewed and why.

Grade issues addressed outside of the requirements listed above will not be considered. Pay attention to your grades. If something doesn't look right, address it immediately! Be sure to follow the guidelines outlined in the "Problem Escalation Policy".

It is your responsibility to ensure that all the grades in T-Square are correct before finals week. After that, the only grade appeal will be about grading your final. 

V. Problem Escalation Policy 

If you need help and/or have a problem, you should contact the following people in the following order:
(1) Your TA
(2) Your Head TA
(3) Your Instructor (e-mail)

If you are not comfortable talking to your TA about a particular issue, please contact the professor ASAP.

VI. Excused Absences and Late Homework Policy

If you must miss an exam for a school-approved reason, it is your responsibility to provide adequate documentation and get approval. If you miss your quiz without prior approval or a valid excuse, you may be approved to take a makeup examination, but you will be penalized 25% of the maximum score possible. 

***CAUTION: the preprinted note from the infirmary stating that you visited the infirmary is not sufficient documentation.*** Please contact the Dean of Students with your excuse and they can provide you with the proper documentation.

Late submission of homework is possible but with the following penalty scale: 
  •  Within an hour of the deadline: Max possible points reduced by 15%. 
  •  Within a day of the deadline: Max possible points reduced by 50%. 
  •  Within a week of the deadline: Max possible points reduced by 75%. 
  •  Anytime after a week of the deadline: Homework gets 0 points, regardless.

VII. Open Door Policy 

The instructor maintains an open door policy. You are free to visit me during the posted office hours or, if you prefer a different time, arrange an appointment (via email) with me. It is very important to contact me as soon as you feel that you might need to. Problems, unlike fine wines, typically do not to improve with age.

The last day you may drop the class for the Fall 2015 term is February 27th. By that date, the students will have feedback on the first two homework assignments and the first quiz.
