Ultra wide band is a generic term to describe radio systems having very large bandwidths. In UWB radio technology, a short pulse is sent out and the receiver looks at its timing or duration compared to a reference to determine its content. Multiple pulses may be required to form a bit of information and since a pulse is very short in time it has ultra wide band frequency spectrum.
According to FCC Notice of Proposed Rulemaking (NPRM) and Notice of Inquiry (NOI), Ultra Wideband (UWB) devices can be used for precise measurement of distances or locations and for obtaining the images of objects buried under ground or behind surfaces. UWB devices can also be used for wireless communications, particularly for short-range high-speed data transmissions suitable for broadband access to the Internet.
This group is related to the discussion of UWB technology ranging from physical layer issues to application level considerations whether it is Multiband OFDM proposal from MBOFDM Alliance by Texas Instruments or using DS CDMA as a physical layer specification for UWB or consideration of UWB based ad hoc network protocol architecture. The issues/problems relating to UWB technology or design of UWB devices or design of UWB software that can be good starting point for future work can also be discussed.
Here you will find links relating to UWB technologies in the market, working groups, academic UWB research programs, web portals for UWB, information about UWB books coming this year.
