Abstract

Interference assessment between the solar power satellite (SPS) system and fixed satellite service (FSS), terrestrial fixed service (FS), wireless LAN, and radio astronomy (RA) has been reviewed in this paper. We have found that interference constraints in the 2.45- and 12.25-GHz bands are relatively severe. Some strategies for the relaxation of interference have been discussed, and co-existence between FSS and SPS systems can be achieved. Interference with RA is the most severe potential interference problem, and further studies will be necessary, e.g., selection of harmless interference transmitter frequencies or effective interference reduction approaches. The 5.8-GHz SPS transmitter frequency is hopefully an alternative frequency that will contribute to small antenna size, small interference potentialities to RA and FSS/FS services, etc.
