26、 present document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Introduction Ultra Wide Band (UWB) radio technology enables a new generation of high-speed data devices for short-range communic
27、ation purposes as well as location tracking and Sensor devices and opens new markets 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
28、interfaces. In addition, UWB devices with an operating bandwidth of several hundreds of MHz up to several GHz allow tens of centimeter-level accuracy real time localization and positioning even in the presence of severe multipath effects caused by walls, furniture or any other harsh radio propagatio
29、n environments. Based on the broad variety of 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 system
30、s like OFDM over spread spectrum based system 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 chan
31、nel bandwidth of a UWB signal gives a specific 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 TS 102 883 V1.1.1 (2012-08)71 Scope The present document su
32、mmarize the available information of possible 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 actual regulation. The present document will be used as a reference for existing and fu
33、ture ETSI standards covering UWB technologies. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
