Residential Indoor Coverage Network Structure Design And Optimization Study

With the development of communication technology and the rapid growth of the number of mobile users, the intensity and coverage of the city traffic requirements is also increasing. Those building large-scale, quality and distribution of dense buildings played a mobile phone signal shielding effect..In building the bottom there are a lot of underground shopping malls, offices, parking lots.Mobile signal is so weak that results in the mobile communications not working properly, forming a shaded area of the phone call or a blind spot; Overlapping signals from different base stations around the formation of a ping-pong effect in the middle floors of buildings, phone switching frequency, and occasionally have a dropped call phenomenon, affecting a customer’s normal use of mobile phones; In building high-rise, the base station antennas to cover the height and angle constraints lead to achieve full coverage, which also formed the blind spots of mobile calls. Within the large-scale buildings, due to the density of mobile phone users, the base station traffic is high, easy to form the channel congestion, lead to the phone line difficulties. Mobile communication network quality, capacity, covering the effect of the operators to improve service level to increase the competitiveness of key indoor wireless micro-cellular coverage in this case. It also reflects the level of a city’s infrastructure development.Concern in this paper, it is expected indoor coverage technology theory and the different requirements of different operators at home and abroad to analyze, integrate theory with practice, to explore a solution for operators and urban indoor distribution trends inThis thesis is divided into the following phases:analysis of design ideas-the overall interior design-including the design of system functions through the analysis of different scenarios of different operators, capacity assessment; interior design program verification-an operator, for example, design, validate, and optimize the indoor distribution system.
