Spring 2009 ECEN4533 Data Communications
Instructor: Dr. George Scheets
E-Mail: george.scheets@okstate.edu
Phone: (405)744-6553
Tentative Office Hours: Engineering South 303
Monday, Tuesday, Thursday, & Friday: 1:30 - 2:30 pm
Wednesday: 10:30 - 11:30 am
Grading: 540 points total. 2 quizzes (40 points), 2 exams (200 points), 1 comprehensive final
exam (150 points), 2 projects (150 points), 1 homework exercise (20 points extra credit).
Late projects are accepted at a cost of 1 point per working day past the due date.
Students missing an exam or the final without notifying the instructor in advance will receive a zero.
At the instructor's option, make-up exams will be available for non-business related reasons, but will be harder. These make-ups will be given on the scheduled make-up time, which is Friday, May 8th, at 1600 hours.
No make-up quizzes will be given.
Grade Scale: 90/80/70 % = A/B/C etc. (initially). Final break points will be curved.
Cheating: Don't do it! Quizzes and exams should be your own work. The projects should be
your own or your team's work. Expect to get an 'F' for the course if you are caught cheating on a
quiz, exam, or project.
Required Text: Computer and Communication Networks, Nader Mir, Prentice Hall, 2007,
ISBN 0-13-174799-1.
Recommended Text: High Performance TCP/IP Networking, Mahbub Hassan & Raj Jain,
