Mapping and visualizing connectivity of telecommunication services is crucial to the work of regulators, government entities and operators since it facilitate the decision-making process to reduce the digital divide. Therefore, this Recommendation provides guidance, especially when it is needed to identify unserved and underserved areas. Moreover, connectivity should be understood not only as the telecommunications service’s presence or absence, but also as a concept that should be built upon different perspectives. This Recommendation defines a high-level framework for mapping and visualization strategies that include guidelines to define first how to identify and measure the level of connectivity and secondly tools and functionalities that are useful in representing the status of this connectivity.
