The Study Of Application And Interference Of Repeater In Mobile Communication Network

As the mobile subscribers and skyscraper are increasing at full speed in the city ,and the requirement of the density and the cover in traffic is also rising constantly. These buildings are in large scale and high quality , there is a very strong function on shielding the signal of the cellularphone.Under the environment such as the substratum in the building , underground market and underground parking etc. the signal of mobile communication is weak, the mobilephone is unable to use normally.so the blind and shade areas of mobile communication have been formed ; In the middle floor , because of the overlay signal from different base stations around , generates the effect of the pingpong , the mobile phone becomes switched frequently,and even lost ,which seriously influence the normal use of the mobilephone; on the high floor in the building ,as restriction of the basic station, the signal is unable to be covered normally, which is a blind area of mobile communication too. In addition, in some buildings, though the mobilephone can be used normally , it is difficult for the mobilephone to reach the standard grade ,because the density of the subscribers is heavy,and the basic station channel is crowd.Especially the network covers the capacity the quality of mobile communication, are key factors that the operator obtains the competition advantage .The cover, the capacity and the quality of the network , reflect service level of mobile network fundamentally, themes of the...
