<p>PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield building prepared for radio LAN preventing the interference in an electromagnetic wave between both up and down floors to stop the lowering of call efficiency or inspection efficiency in the electromagnetic wave shield building having a radio LAN system set in a multi-layered story. SOLUTION: An electromagnetic wave shield building prepared for radio LAN sets a radio LAN system in a multi-layered story, every floor is constituted of a wall 4 applying an electromagnetic wave shield 11 thereto, a floor 5 consisting of a deck plate 12, a ceiling 6 and an outside window 8 applying no electromagnetic wave shield thereto, and a wave originating antenna 14 is set in the vicinity of a core wall in every floor. The interference in electromagnetic wave between both up and down floors is prevented to stop the interference in the electromagnetic wave causing the lowering of call efficiency or inspection efficiency, and smooth operation of the radio LAN system can be accomplished.</p> |
