This paper presents an optimization model for antenna selection and deployment in ceiling mounted, single and multi-cell RFID systems. The proposed model utilises a three-dimensional (3D) antenna radiation pattern, taking into consideration of both antenna half power beam width and downtilt angle. Specifically, we have analysed the effects of cell structures on detection probability in single-cell...
This paper addresses the interference issue in a passive multi-cell radio frequency identification (RFID) system. Instead of considering the negative effect of interfering RF signals from adjacent readers, we investigate its constructive effect in providing extra RF power to tags in the cell of the desired reader system. Through detailed simulation and experimental analysis, it is found that the unsynchronised...
