MotivationsMotivations

Recent Development– Cellular system: 3G, 4G, video, game,

– WIFI everywhere

– WIMAX,

– UWB, no cables

– Bluetooth, small devices connections

Job Market – Probably one of most easy and high paid majors recently

– Intel changes to wireless, Micron will follow? Cypress

Research Potential – multiuser communication & Cognitive radio are still an

open issues.

Teaching StylesTeaching Styles

Slides plus black board Slides can convey more information in an organized way Blackboard is better for equations and prevents you from not coming. A lesson from last semester: math

Course Website Print handouts with 3 slides per page before you come Homework assignment and solutions Project descriptions and preliminary codes

Feedback Too fast, too slow, small class advantages. Presentation, English, …

Reasons to be my studentsReasons to be my students

Wireless Communication and Networking have great market Usually highly paid and have potential to retire overnight Highly interdisciplinary Do not need to find research topics which are the most

difficult part. Research Assistant, Stipend Free trips to conferences in Alaska, Hawaii, Europe, Asia… A kind of nice (at least looks like) Work with hope and happiness Graduate fast
