This paper presents the analysis of a particular case of study consisting of a full pallet with multiple UHF tags readings using a single handheld reader and following the EPC Class1 Generation 2 standard [1]. To perform the analysis, an empirical experiment to obtain the RSSI (Received Strength Signal Intensity) transmitted from a handheld reader and the number of readings for each tag over a fixed period of time was designed. A pallet consisting of 15 boxes filled with plastic objects was employed and measures were taken at different reading angles. To experiment with different materials the configuration of the test pallet was modified including some metallic objects in two random boxes. Finally, some conclusions regarding correlation between RSSI, tag location and number of tag readings are presented for both cases.
