发明名称 BUILDING WITH ELECTROMAGNETIC SHIELD STRUCTURE FOR INDIVIDUAL FLOORS
摘要 A building with an electromagnetic shield structure for individual floors uses an electromagnetic shielding material in a body of the building and in openings such as windows and doorways, and the external wall surface of the building is covered with an electromagnetic shielding layer. An electromagnetically shielded space within the building is divided into individual floors by floor partitions using an electromagnetic shielding material. Wireless communication utilizing electric waves is carried out within the building, with the same frequency band or any desired frequency band being allotted to each floor. With the above arrangement, sets of communications equipment using the same frequency band on one floor can communicate with one another without interfering with sets on another floor, even though the sets of equipment on the other floors use the same frequency band. Accordingly, by installing sets of communications equipment of a fixed frequency band irrespective of the number of floors in the building, information can be communicated freely within the building.
