Test method for UHF RFID readers in dense environment

Due to the lack of criterion on the efficiency of UHF RFID systems in dense environment, this paper shows a novel test method for UHF EPC C1 G2 RFID readers in a dense environment. A new parameter based on identification rate that describes the performance of readers working in dense environment is demonstrated and a new test method to generate this parameter is given. Experiment show that this test method is capable of measuring the performance of readers in dense environment.
