Measurement and functional validation of detect and avoid ultra wideband devices

Ultra Wideband (UWB) radio regulations have been discussed for long time because of the potential interference that UWB radios can cause to other radio systems with which they share the spectrum. A mitigation technique for UWB devices named Detect and Avoid (DAA) has been proposed as a potential solution to reduce the risk of interference. DAA testing presents specific challenges related to the low emission power of UWB devices, the validation of spectrum sensing algorithms and timing considerations. This paper presents the design of a test bed to validate the correct implementation of DAA mitigation techniques by UWB devices. It describes the testing challenges and the related test bed design solutions for both radiated and conducted test methods. A number of measurement campaigns against UWB devices with Detect-only capabilities were separately conducted at three test beds in China, Spain and Italy within the frame of FP7 project WALTER. The results of the measurements were analyzed and compared. As DAA is a basic form of a cognitive radio technique, the proposed test bed design and procedures could support future test implementations for cognitive radio devices.
