Signal loss of RFID technology with short distance and high frequency

To obtain an automatic and intelligent monitoring system, RFID is used to aid with CCTV system which is an innovative method. Therefore, some problems exist as integrating these two technologies, and signal loss is one of the problems as RFID signal is vital to the final result. Since the targets which are necessary to be monitored through the CCTV system are dynamic, the experiments in this research are set to obtain dynamic data with specific environments, which traditional signal loss equations are not available. Empirical loss equation is accurate but computational complexity, a simply empirical loss equation is found in this research and the results are compared with the other existing loss equations.
