Coverage maps are modelled on predictive coverage and therefore may not reflect the ‘on the ground’ experience for all end users. There are several factors that can impact mobile coverage including buildings, foliage/trees, bad weather, hills or mountains, the number of nearby people using the same mobile site and hardware compatibility.The assumptions that underpin these predictive coverage models differ across the MNOs. The assumptions can also change across time for a given MNO. These changes could mean that increases or decreases in the measurement of coverage from year to year may not necessarily reflect changes in the predicted ‘on the ground’ experience of end users. Instead, the changes may reflect differences in assumptions that underpin the modelling of the predictive coverage maps or variations in the precision/accuracy of the models. Slight fluctuations in coverage areas from year to year could also result from optimisation activities undertaken by the MNOs, such as adjusting the tilt of antennas to reduce interference. Additionally, the introduction of new versions of prediction models/tools and potential differences in rounding and aggregation can result in minor variability in coverage predictions year to year.In addition, from 2018 to 2021, the MNOs have provided coverage maps based on different standard of coverage. In providing coverage maps in accordance with the RKR, the MNOs have interpreted the requirements differently. Telstra’s coverage maps are based on predicted coverage for external antennas and TPG’s are based on predicted outdoor coverage. Optus’ coverage maps are to a large extent reflecting predicted coverage for external antennas. In general, coverage maps which are based on external antenna coverage predict wider coverage areas than coverage maps based on outdoor coverage.
