The GRETA architecture for energy efficient radio identification and localization

This paper presents an overview of the innovative solutions developed within the Italian project GRETA (GREen TAgs and sensors with ultra-wide-band identification and localization capabilities), whose aim is the development of a distributed and comprehensive system for identification, localization, tracking and monitoring in indoor scenarios. The system is based on hybrid UWB-UHF RFID tags, and the realization and experimental validation of novel tag prototypes based on environmentally friendly materials is a major achievement of the project.
