As noted, the tracking indicator adopted for the target is the proportion of the population within range of a mobile signal. To this could be added an affordability indicator relevant for LDCs such as the price of a mobile broadband subscription as a percentage of income. It could be argued that if LDCs have reached appropriate thresholds for these two supply side indicators—100% mobile broadband coverage and prices less than 5% of per capita income—then they have created the necessary preconditions for Internet use and achieved the target.
