Retail Merchandise Tracking System

Looking for an item in a large department store or mall can be like searching for a needle in a haystack, but that could change thanks to a hybrid location identification system that uses radio frequency transmitters and overhead LED lights, suggested by a team of researchers from Penn State and Hallym University in South Korea led by Mohsen Kavehrad, W.L. Weiss Chair Professor of Electrical Engineering and director of the Center for Information and Communications Technology Research at Penn State.
