Welcome to the Drexel Wireless Systems Laboratory

"Wireless Innovations for Tomorrow"

We are a research group focused on applying techniques from many different disciplines to develop and commercialize revolutionary new wireless technologies

Our Lab

The central philosophy of the Drexel Wireless Systems Laboratory (DWSL) is to take a systems-centric view of new and emerging wireless technologies using a combination of interdisciplinary research and hardware prototyping. Two recurring themes involve the extension of: i.) software defined / cognitive radio to modalities beyond only radio, and ii.) the principle of "diversity" outside of exclusive use in radio frequency communications. The realization of this research philosophy has taken the following forms:

  • Interdisciplinary research across traditionally separate areas towards practical applications. For example, DWSL smart textile research involves collaboration between engineering, medicine, and fashion design for the realization of unobtrusive biomedical smart textile systems. Similarly, DWSL reconfigurable antenna research is not only informed by computational electromagnetics and radio frequency design. The research also considers how reconfigurable antenna design influences, and is influenced by, metrics in algorithms pertaining to link adaptive modulation, ad-hoc network interference mitigation, interference alignment, dynamics spectrum access, network routing tables, as well as physical layer encryption key generation and user authentication.

  • Hardware Prototyping of systems usually considered only theoretically or by simulation. Specifically, this goal involves extending emerging technologies in software defined and cognitive radio to include: i.) transceiver hardware reconfigurability, as opposed to flexibility only in modulation and signal processing software, and ii.) optical and ultrasonic communication modalities, as opposed to exclusive use of radio frequency (RF).

  • Extension of the principle of "diversity" outside of exclusive use in RF communications to hybrid modality communications systems that make simultaneous, coordinated use of two or more signal propagation media. Examples of this extension include: i.) hybrid radio frequency and free space optical communications for indoor office local area networking and ii.) hybrid radio frequency and ultrasonic communications for local area networking in specialized military and industrial applications.

Ongoing projects at DWSL encompass a wide ranging number of research areas that reflects its systems level approach to studying and solving problems in wireless communications. The lab is also working with faculty members across the university to extend its research impact into diverse areas such as medicine and fashion for biomedical applications.
