RADIO WAVE BLOCKING METHOD AND RADIO WAVE SHUTTER
PROBLEM TO BE SOLVED: To make it possible to prevent a communication network of the connection destination of a mobile terminal from automatically switching to a communication network having weak electric field intensity.SOLUTION: A radio wave blocking method for attaching a radio wave shutter 100 including a radio wave blocking sheet 110 for blocking a radio wave 500 other than a set transmission frequency in a state of covering a window 300 of a building includes the steps of: the radio wave blocking sheet 110 setting the transmission frequency on the basis of electric field intensity in a room 10 of a radio wave at a data communication frequency used in data communication and electric field intensity in the room 10 of a radio wave of a voice call frequency used in a voice call; and the radio wave blocking sheet 110 blocking the radio wave 500 other than the transmission frequency.SELECTED DRAWING: Figure 1
【課題】携帯端末の接続先の通信網が、電界強度が弱い通信網へと自動的に切り替わることを防止可能にする。【解決手段】設定された透過周波数以外の電波５００を遮断する電波遮断シート１１０を有する電波シャッター１００を、建物の窓３００を覆う状態で取り付ける電波遮断方法であって、電波遮断シート１１０が、データ通信にて使用されるデータ通信周波数の電波の室内１０における電界強度と、音声通話にて使用される音声通話周波数の電波の室内１０における電界強度とに基づいて、透過周波数を設定するステップと、電波遮断シート１１０が、透過周波数以外の電波５００を遮断するステップとを有する。【選択図】図１
