What factors affect the range of the RFDC transmissions?
In addition to those listed above, the most common operating environment factors that affect range are water and metal. Many materials, such as wood or paper, hold small amounts of water, but when many papers are held together, as in a records room for example, the effects of this can equal a thin wall of water. Water affects 2.45 GHz transmissions more than other frequencies, as this is the frequency that excites water molecule electrons. Most microwaves used for cooking operate within this range. Microwaves heat the water in a product, which is why food on a paper plate will get hot, but the plate will not. Back to Question List • What frequencies are used with RFDC devices? Typically 2.45 GHz. Back to Question List • Can RFDC be used around other RF systems such as RFID? Yes, though caution needs to be used. There is reason to expect interference from one RF source to another. Spread spectrum systems are designed to mitigate most of this interference, though in extreme cases, the re
