RFID Journal Glossary

Ultra-Wideband
Any radio technology having a bandwidth exceeding the lesser of 500 MHz or 20 percent of the arithmetic center frequency, according to the Federal Communications Commission (FCC). Due to the extremely low emission levels currently allowed by regulatory agencies, UWB systems tend to be short-range and used indoors. High data-rate UWB can enable wireless monitors, the wireless printing of digital pictures from a camera without an intervening personal computer and the transfer of files among cell phone handsets and other handheld devices, such as personal digital audio and video players. UWB is used in location systems and real-time location systems.
