Ultra-wideband (UWB) rules and design compliance issues

In April of 2002 the FCC published its Report and Order governing the use of UWB devices. This established Subpart 15F of the Rules. UWB technology is used in many applications including imaging devices and communication. This paper will present basics of UWB devices and the FCC's response to their proposed uses and limitations. UWB interfering effects on radio communications and satellite positioning systems are also discussed. Requirements for UWB, including changes published in March 2003, will be presented as well as the implementation of the associated test procedures, published in the FCC's Report and Order.
