Examples of how transmissions can be spread in time during the observation period Tobs. a Example of an evenly distributed spreading. b Example on the other hand of using all available transmission time in a single burst. c Also an example of using all available transmission time in a single burst, but due to the offset in the burst are there actually 2 burst in a single observation period Tobs. Therefore, the device in example cdoes not conform to the duty cycle regulations
