nation of policy options and relevant strategies and the projection of time needed to obtain agreements on geostationary orbit availability, microwave frequency allocation and microwave exposure standards. 4.1 Definitions and Interpretations One of the very first major issues in negotiating international agreements with respect to geostationary orbit availability, microwave frequency allocations and microwave exposure standards will be a definition of power transmission by microwaves from space, bearing in mind both the legal and scientific implications. In a recent draft report the International Radio Consultative Committee (CCIR) defined the scientific parameters of 1free-space energy transmission by microwaves' as "the point-to-point transfer of energy through free-space by a highly collimated microwave beam". The report added that this technique constitutes "a unique technology" which "differs from the use of microwaves in free-space for point-to-point communication purposes because of its very high efficiency and the magnitude of the power" and also differs from "the traditional methods of receiving and processing radio energy n m communications and location services. Closely associated with the issue of definition of microwave power transmission is that of 'telecommunication', particularly of the word 'signals' as it is used in the definition of telecommunication in the 1973 ITC. The definitions and their interpretations are key issues because the position taken in relation to them may determine whether or not the ITU has competence to deal with microwave energy transmission from space. This, in turn, may have far- reaching effects on U.S. policy options and strategies in
