During 2017, digital audio broadcasting (DAB) replaces frequency modulation (FM) broadcasting and becomes the only technology for national terrestrial audio broadcasting services in Norway. As Norway is the first country that replaces FM completely with DAB, it is of great importance to measure the signal strength of such a technology in massive deployments and to tune a simulation model as a reference for future studies. Therefore, field measurements of received signal strength are carried out in a typical Norwegian area in this work. Based on the data obtained from the measurements, a simulator with a recent empirical propagation model, namely, ITU-R P.1546-5, has been calibrated. The findings, in short, suggest that different clutter codes and attenuation parameters have to be tuned according to the measurement results in order to increase the precision of the simulation model. By properly tuning the parameters in the model, the precision has increased 91.7% compared with the default configuration. In addition, the tuned model is validated through another field measurement in a different area and obtains an increased precision of 72.9%.
