The performance of radio waves in open environments has been studied for years. In contrast, the behavior of RFID (Radio Frequency Identification) inside metal enclosed areas is not yet thoroughly understood. The first part of this research project focuses on the 3-D mapping of RFID signal strength inside a 12m (40’) refrigerated marine container. The container was instrumented with 3 different types of radio frequency emitter: 2.4 GHz reader; 915 MHz reader and 433 MHz RF transmitter. The main goal is to find a frequency/configuration that would allow real time reading of the temperature in a shipment of perishable products using RFID.
