The worldwide spectrum masks for UWB communication devices 1.3 Applications UWB technology can be applied in a wide variety of applications. Based on the FCC guidelines UWB technology is deployed in two basic communication systems. S High data rate IEEE 802.15.3a S Low data rate IEEE 802.15.4a The high data rate WPANs can be defined as wireless data connectivity between the hosts PC high quality real time video player and so on and the associated peripherals keyboard mouse speaker VCRs and so on . It will remove the wires and cables with high transfer data rate and rapid file sharing or download of images graphic files. In other hand the low data rate wireless communications will be primary focused on position location applications because of UWB s centimetre accuracy in rages of 100m. In the other aspect UWB applications are classified three major categories. S Communications and sensors S Position location and tracking S Radar Ultra-Wideband Antenna 23 Applications for wireless communications and sensors are the most attractive one due to the high speed data transmission and low power consumption. UWB will be applied to the movable wireless devices such as keyboard mouse printer monitor audio speaker mobile phone and digital camera. It will give us convenient and enrich daily life because the wires will disappear. And sensors which will be used to secure home automobiles and other property also make our life more comfortable. Specially it will contribute to patients in the hospital by using the monitoring of their respiration heart beat and other medical images with wireless devices. Position location and tracking also have a potential in UWB applications. Due to the centimetre accuracy UWB can be used to find a lost something or .
