Abstract
According to the requirements of mobile signal indoor depth coverage and the limitation of exist-ing coverage solutions,a radio frequency system based on community antenna television(CATV) coaxial cable is proposed.The system principle and several key problems are analyzed,and parameters of the sys-tem design are calculated.Then,the structure of three main components—combiner,distributor and intelli-gent terminal and key modules such as impedance matching filter,synchronization,and amplifier are de-scribed.The field test results show that the proposed system meets the requirements of design and applica-tion,realizes the signal coverage of a 160 m2apartment,improves the cell measure report(MR) coverage, meanwhile has no influence on the performance of indoor distribution system.It has the advantages of low cost,fast construction and simple coordination compared with the existing solutions and it is a novel and practical way to realize indoor depth coverage.关键词
