Implementation at UVM

UVM had a recently implemented a communication systems laboratory course but provided students with no device-level experience. To address this shortcoming, our approach is to migrate the present systems-level experiments into three existing theoretical courses. The laboratory course will be updated by adapting/implementing the USF model focusing on the characterization communication devices.

Through this approach, we contend that undergraduates at UVM will be able to develop a diverse skill set applicable for future work in digital and/or wireless communication systems.

UVM’s ECE program is relatively small (~20 graduates/year) and thus our implementation of a comprehensive, undergraduate communications curriculum may serve as a model for similarly sized departments.

A Comprehensive, Laboratory-Enhanced Communications Curriculum

Abstract: Over the past decade, wireless communications has come into its own and is posed to become a ubiquitous technology with the recent arrival of 3G cellular, wireless local area networks and wireless sensor networks. As such, today’s graduating electrical engineers need marketable skills which are typically not developed in undergraduate curricula. This project address this need through significant enhancements in the undergraduate communications curriculum offered by the Electrical and Computer Engineering Department (ECE) at UVM. The emphasis of these enhancements lies in the integration of hands-on experience in three typically, theory-based telecommunication courses and a separate lab course having a wireless communication device focus.

Exemplary Pedagogy Adapted

The activities, enabled by a NSF CCLI A&I award, feature infrastructure development and adaptation of exemplary pedagogy from the Wireless and Microwave Instruction (WAMI) program at the University of South Florida (USF). The USF program, supported through a NSF grant (DUE-9650529) and industry support, developed a state-of-the-art undergraduate laboratory course focusing on the integration of circuits and systems aspects of modern wireless applications. The WAMI laboratory is equipped with an array of CAD/CAE software packages and a complete set of microwave and RF instrumentation. The USF course now has a per-semester enrollment of ~50 students.

Our objective is to adapt USF’s approach for a program significantly smaller in size.
