Theory Analysis of the Leaky Communication in Underground and Discussion on Actualizing Projects of the System

For probing into the effectively actualizing projects of the leaky mobile communication system in underground, the distributing rule of the leaky electromagnetic fields is researched. The key factors of influencing the leaky electromagnetic fields are deduced by the theory analysis of transmission of the wireless leaky electromagnetic fields in underground. The application of the leaky communication is discussed, and the three actualizing projects of mobile communication in underground on different occasion, what is used leaky cables and amplifiers. The application model of the leaky communication system in underground is founded, and author gives voice to the organizing net of the system. The circumstance and actuality of transmission of the leaky electromagnetic fields in underground are analyzed, and the mutuality opinions of the choice of the application equipment and the distributing of the electromagnetic fields intensity of the system are advanced. Discussion results indicate that mobile communication system with leaky cable and both directions amplifier in underground is actualized better.
