て上記情報通信機器に妨害を与える。However, for example, noise radio waves propagating from an external power line or noise radio waves from a motor in a building may interfere with the above-mentioned information communication equipment in a building through a substation or indoor power wiring, or by an external communication line. Also interferes with the above information and communication equipment through indoor communication wiring.
また、空調ダクトを介して外部の雑音電波が建物内に
導入され、上記情報通信機器に妨害を与える。In addition, external noise radio waves are introduced into the building through the air conditioning duct, and interfere with the information communication device.
さらに、強力な電波源である移動無線局や固定無線局
から発射される電波も情報通信機器に混信障害を与え
る。Further, radio waves emitted from a mobile radio station or a fixed radio station, which is a strong radio wave source, also cause interference with information communication equipment.
以上の原因により、現在では電波を利用した高信頼の
情報伝達は不可能となっている。Due to the above reasons, highly reliable information transmission using radio waves is currently impossible.
一方、電波資源は限られたものであり、利用し得る電

ねばならない等の問題があり、電波の有効な活用ができ
ない。On the other hand, radio resources are limited, and the number of available radio channels is limited to about 10 to 100 channels. Therefore, if a large number of information communication devices are to be used, interference will occur between the information communication devices, and as a result, the number of information communication devices that can be used at the same time will be limited. There is a problem with radio waves, such as having to wait until the use of the radio waves ends, and the radio waves cannot be effectively used.
以上のように、建物には内外の電磁波による障害があ

いばかりでなく誤動作も多い等の難点があり、従って電
波通信を使うことが要請されているが、上述のように電
波通信には外部からの電波の侵入や外部への漏洩という
問題があり、その実用化を阻んでいた。However, infrared rays have strong directivity and have not only low transmission capability but also many malfunctions. Therefore, it is required to use radio wave communication. There was a problem of invasion and leakage to the outside, which prevented its practical application.
