The present paper analyses and measures the effects that the presence of a metallic surface can induce on the integrated antennae of HF RFID systems operating on a 13.56 MHz frequency. The results of the conducted measurements have been compared with those arrived at by means of the Ansoft HFSS application. Thus, the conducted tests and simulations reveal the fact that the resonant frequency increases...
In order to reach a high performance level in a street lighting control system, two important aspects must be taken into account: the selection of the adequate communication protocol, on the one hand, and the selection of the network topology that supports the architecture, on the other hand. Given these circumstances, the present paper focuses on an assessment of the performance of the mesh and tree...
