### <a name="SetMbObsDenmBeacon"></a>SetMbObsDenmBeacon

This module specifies a set of observations for a subset of DENM Use Cases listed in TS 103 759 Annex D.2 (see table D.3). The data types used for specifying the set observations per target class

 and the data types used for detailing other evidences which may need to be included in the report are given.

 This is a set of observations for the target class c-DenmTgt-BeaconCommon,

 where the trigger conditions for different observations are as follows.

   - @param Beacon-IntervalTooSmall: The difference between the generation time of two consecutive DENMs related to the 

 same traffic event (same actionId and detectionTime) transmitted by the same ITS station (same stationId) is 

 less than 80% of the minimum threshold value of the DENM repetition interval. This minimum threshold is set to 100 ms,

 considering the list of Day1 uses cases referenced in TS 103 759 table D.3 specified in C2C-CC Basic System Profile [[i.11]](#references)

 and C-Roads specifications [[i.12]](#references). The difference is calculated as the difference between the referenceTime in the second DENM and the

 referenceTime in the first DENM.
