3. Whence 582/682? Over one-third of engineering time is spent on writing, editing, and preparing reports and oral presentations. A 1987--1991 survey of OSU Engineering alumni and employers showed preparation mismatched to importance on four topics: –writing skills, oral skills, problem solving, teamwork. A.B.E.T. encouraged increasing both design experience and teamwork. EE582/682 was introduced in 1995

6. From Student Feedback… More team time during regularly schedule hours –16 team hours –7 lecture hours –6 presentation hours More lab access –10 hours/week open lab (and by appointment) –Lab shared with EE508 Review meetings (weeks 2, 4 and 8) Peer evaluations Interim report serves as first iteration on the final report Clarity in schedule, expectations, and evaluation criteria.

Design Specifications Build and demonstrate a prototype modem –FCC compliant, 902-928 MHz –Distance 8.25m (DL569 length) –Character error rate 0.001 (simple to measure) –Data rate 9800 bps (proven reachable) –Development cost$100 (actual budget) –Packet duration7 sec –Delay30 sec (processing time) DL569 PCs Files and typed text Realistic and realism UHF Wi-Fi; 3 credits, 1 quarter

9. Resources for Success Instructors: office hours and lab hours (14 hours/week) Communications Primer and two lectures –Basics of digital communications –Pointers to further information Web Links at course web page –Starting points for RF components, antennas, coding, PC I/O, FCC Free-ware on-line and Matlab toolboxes Texts on reserve at SEL EE582 preparation

10. Hints for Success Start early –Make good progress before other courses become intense –For reporting, reserve time for editing Team-work –Identify tasks and partition effort among team members Take advantage of course resources Test sub-systems and pay attention to interfaces In software, leave parameters as variables (for easy mods) Respect team-mates Have fun building a working device
