[Abstract]:In order to win more users and seize the market, operators should actively innovate technology and increase investment. It is necessary to maintain the advantages of the traditional 2G business represented by GSM. At the same time, we must lay out the mature 3G network represented by WCDMA/TD-SCDMA and the LTE4G network which is the key construction in the future. Therefore, the pressure of network construction is increasing, how to better solve the signal coverage, meet the needs of users, multi-network long-term coexistence and collaborative development is an urgent problem to be solved in the future. With the gradual deepening of network construction, outdoor area coverage has been basically completed. Service statistics show that more than half of the traffic of 2G services takes place indoors, and more than 69.7% of the data services in 3G networks also occur in indoor environments. At present, the global communications industry has embarked on a step of converting from 3G to 4G. The subsequent development is bound to continue the rhythm of the early network construction, so the network depth coverage has gradually become the focus of attention of operators. Building indoor distribution system is an important means to improve the depth of network. It can effectively attract traffic and enhance users' perception, while extending the coverage area, providing greater network capacity and attracting more users. In recent years, it has been greatly developed because of the higher consumption of communication services and services, and the increase of operating income. This shows the mobile communication network to the indoor coverage of the importance. The optical fiber multi-standard distribution system is a highly integrated indoor coverage system for mobile communication, and the system has the advantages of miniaturization, intensification and energy saving. Thus, the family coverage problem of mobile communication signal is solved, which is convenient and fast and low cost.
