Introduction Ultra Wide Band (UWB) radio technology enables a new generation of high-speed data devices for short-range communication purposes as well as location tracking and Sensor devices and opens new markets
35、 with a variety of innovative applications. UWB devices may form an integral part of other portable electronic equipment such as future generation cellular phones or laptops equipped with UWB enabled short-range air interfaces. In addition, UWB devices with an operating bandwidth of several hundreds
36、 of MHz up to several GHz allow tens of centimetre-level accuracy real time localization and positioning even in the presence of severe multipath effects caused by walls, furniture or any other harsh radio propagation environments. ETSI ETSI EN 303 883 V1.1.1 (2016-09) 7 Based on the broad variety o
37、f different applications and the broad possible frequency range of operation the number of possible deployed physical signal formats can be very large. The existing range of physical signal and modulation formats range from traditional carrier based systems like OFDM over spread spectrum based syste
38、m to carrier less systems based on base band pulses. The frequency regulation on the other side only defines a single set of transmission limits and values, which have to be fulfilled by all systems under the UWB regulation. Furthermore, the very high channel bandwidth of a UWB signal gives a specif
39、ic challenge to the needed measurement setup and the procedures. Existing measurement methods need to be extended and new possible techniques should be described in the present document. ETSI ETSI EN 303 883 V1.1.1 (2016-09) 8 1 Scope The present document summarizes the available information of poss
40、ible measurement techniques and procedures for the conformance measurement of various UWB signal formats in order to comply with the given transmission limits given in the current regulation. The present document will be used as a reference for existing and future ETSI standards covering UWB technol
