BIPT draws up mobile coverage maps (Atlas) based on data communicated by operators. These data are validated: via a validation process, BIPT checks that the maps are consistent with the measurement drive tests run before every update.

BIPT runs these tests on the entire Belgian territory. To be published, the maps have to achieve a minimum level of reliability. The map shows the presence of a signal depending on its strength (satisfactory, good or excellent signal).



Certain operators use a network management technique called RSRP boosting aiming at improving the performance of their 4G networks. The impact of RSRP boosting on the performance can be positive or negative, depending on the circumstances. Operators can choose different strategies concerning RSRP boosting. The latter can be used, with different degrees of intensity, throughout the national territory, or in parts of it. This difference in strategy has an impact on coverage maps. The coverage of operators using RSRP boosting seems indeed better than the coverage of operators who do not implement it.

RSRP boosting also increases the number of bars indicating the coverage quality, displayed on smartphones. Therefore, even if the signal is shown in orange (satisfying) in an area, the quality of user experience may not be optimal. In order to obtain a more complete picture regarding quality, BIPT also measures the quality of experience on mobile networks. Furthermore, it complements its coverage survey with the collection of data directly coming from the field.
