Wireless Networking Systems Lab

The Wireless Networking Systems Laboratory (WNSLab) was established with support from the state of Tennessee in 2004 to conduct cutting-edge research in advanced radio systems and statistical signal processing. WNSLab has a track record in support of various research projects funded by government agents (NSF, ONR, AFRL, ARO and ARL) and industry (Panasonic and Nissan North America). The first Ultra-wideband (UWB) Time Reversal Testbed was developed in the lab thanks to the support by the Office of Naval Research (ONR). With sponsorship via an ONR Earmark project, a large-scale cognitive radio network testbed was developed and later extended to explore indoor sensing and target tracking. Recently, some IoT devices were acquired and used in the lab to conduct research in IoT and smart manufacturing security
