Mobile Communication Indoor Coverage System Research And Realization

As the city grew rapidly and mobile users in the high-rise building more and more, traffic density and cover requirements are rising. These buildings large scale, quality good, on mobile phone signals have strong shielding effect. In large buildings underground mall, the low-level environment of underground parking, mobile communications, weak signal phone unable to normal use of mobile communication, formed the blind and shadow area; In the middle of the floor, because from around the overlap, different stations signal generated ping-pong effect, cell phones, even drop the words, frequent switching severely affected the normal use; mobile phone In high-rise buildings, and affected by the base station antennas, height limit is not normal coverage, mobile communication blind alleys. In addition, in some buildings, although cell phones can normal conversation, but a user density is big, base station channel crowded, mobile phone online difficulties.Mobile communication network coverage, capacity, quality is the operators of key factors obtain competitive advantage. Network coverage, network capacity, network quality fundamentally manifest the mobile network service level, is all mobile network optimization work theme. Indoor coverage system it is in this context of generation.The basic principles of indoor coverage system is to outdoor signal through wire introduced into the room, then through a small antenna to send out the signal so as to enhance the level of indoor coverage. Some works from this experience, analysis of Indoor coverage system, Discusses the design characteristics of different scenes and matters needing attention.According to the Multi-network fusion development background, Put forward multi network fusion indoor coverage system construction principle,process,some guidelines and Solutions, Achieve the goal of Supporting mobile communication indoor coverage system.
