解釋
接駁水源-
The millimeter has the largest frequency band and the highest velocity of communication, but it has the highest cost and technical defaults : multi - path effect, reflect and scatter caused by cloud, smoke, water - dropping, the buildings, the grounds and its shape, the interference caus ed by the thunder, the complexity of device, difficult maintenance, and so on. now the band of the leakage coaxial line is up to 3ghz, leakage coaxial line has some advantages : good adaptability to cloud, smoke, water - dropping, the buildings, the grounds and its shapes, good steady field, it has some technical defaults : lower resolution for location and measuring velocity, the more complex of its sending - receiving relay devices, weak anti - interference, the strict demand for the hole size in the line, the cleaner work environment and the higher cost
毫米波具有最大的帶寬和最高的通信速率，但也有最高的成本要求和較難克服的技術問題，即傳播的多徑效應，降水、雲霧、地形、地貌、建築物等的反射散射，打雷時的嚴重干擾，設備復雜，維護困難等等；泄漏同軸電纜的帶寬目前已做到3ghz ，具有對地形地貌建築物的適應性強，場強穩定，但它的定位測速精度低，它的收發中繼設備較復雜，抗干擾能力低，電纜上的開槽有著嚴格的尺寸要求，工作環境要求清潔，成本較高；傳統無線感應技術具有結構簡單，成本低廉，維護方便，定位精度較高的優點，但是，它沒有抗干擾能力。 -
