The ITU Radiocommunication Assembly considering a) that the Radio Regulations (RR) specify three “radio Regions” (RR Nos. 392 to 399); b) that, between the three Regions, there are many differences in allocated services and allocated band limits; c) that worldwide allocations can: simplify the Table of Frequency Allocations; ease coordination requirements; promote equipment availability for international markets and reduce production costs, thus helping to meet the requirements of developing countries in particular; facilitate activities that depend on internationally operable equipment (i.e. flight traffic control); d) that the factors to consider when evaluating the need for a worldwide allocation versus separate regional allocations in a specific frequency range need to be delineated.
