This paper provides an overview of three key dimensions that are considered to influence the optimal use of radio spectrum, and examples are given of how these might be "measured" in practice. The key efficiency dimensions are technical, economic and functional. All of these should be considered when assessing the extent to which optimal use of spectrum is being achieved. In general, maximising economic efficiency would seem to be the priority in the case of larger, national services such as cellular or TV broadcasting. Conversely, for more specialist applications such as private mobile radio or air traffic control, functional efficiency or "suitability for purpose" should be the overriding concern. In both cases, there is a need to optimise the technical efficiency in so far as this can be achieved without negating the functional benefits or rendering the service economically nonviable. There is no single, all-embracing algorithm that can compare the efficiency of one spectrum-using application with another. Hence the measurement and comparison of spectrum utilisation efficiency may rightly be considered to be as much an art as a scientific process. (3 pages)
