SPS International Agreements

If the result of the aforementioned broad interpretation is acceptable to the ITU, and there is little reason to believe that it would not, it would be within the competence of ITU to follow its IFRB procedures relative to the registration of frequency assignments in case of microwave power transmission in the same manner as it has in relation to other frequencies of the radio spectrum. However, before any such procedures can be prudently put into effect, it will be necessary for the ITU to determine through appropriate studies and relevant findings any radio frequency (RF) interference, including the detailed and specific effects on radio astronomy, ship-borne radar, communications systems and other services. It may be noted that some preliminary studies have already been undertaken by the International Radio Consultative Committee (CCIR), an ITU organ, in connection with preparations for the 1979 WARC. Such studies will have to be periodically updated to keep abreast of scientific and technological developments which may result in reduction or possibly even in complete elimination of RF interference as may perhaps be the case if laser beams were used for power transmission. 3.3 Microwave Exposure Standards One of the major concerns involving the transmission of microwave beams from geostationary satellites to selected places on earth relates to the all-important question of what effect exposure to such transmission is going to have on humans and biota
