摘要

P To provide a visibility determination method between radio stations which premises installation of the antenna of the radio station in a veranda or installation ON a building wall, reduces huge calculation amount, is more realistic and simultaneously improves determination precision. PSOLUTION: The method determines visibility between a base station X and a subscriber station which constitute a radio circuit. A visibility determination point assumes an installation place of the subscriber station which is installed ON a building 15, and constitutes a radio circuit with the base station X. When a shelter does not exist ON a propagation path of the radio circuit and the side plane of the building 15 is recognized which can take its overall view from the base station X, a certain point ON a vertical line constituting the side plane is made the visibility determination point and the visibility between the base station X and the subscriber station is determined by calculating visibility between the determination point and a candidate point of the base station X.
