【摘要】：为争取更多的用户,抢占市场,各运营商积极创新技术,增大投入,既要保持传统的以GSM为代表的2G业务所取得的优势,还要全力布置市场成熟的以WCDMA/TD-SCDMA为代表的3G网络,同时还要兼顾未来重点建设的LTE4G网络。所以,网络建设的压力越来越大,如何更好的解决信号覆盖,满足用户需求,多网长期共存协同发展是今后迫切需要解决的问题。伴随着网络建设的逐步深化,室外区域广覆盖已经基本完成。业务统计情况表明,2G业务有超过一半的话务量发生在室内,3G网络69.7%以上的数据业务也是发生在室内环境,而当前,全球通信产业已经迈开由3G向4G转换的步法,后续的发展势必会延续前期网络建设的节奏,所以,网络深度覆盖逐渐成为运营商关注的焦点。建设室内分布系统是改善网络深度的重要手段,它能够有效吸引话务量并提升用户的感知,在延伸覆盖区域的同时,提供更大的网络容量,吸引更多的用户,产生更大的通信业务和服务消费量,从而带来营业收入的增加,因此近年来获得了大力发展。由此可见移动通信网络对室内覆盖的重视程度。本文的光纤多制式分布系统是一种高集成度移动通信室内覆盖系统,且系统具有小型化、集约化、节能化的优点。从而解决移动通信信号的家庭覆盖问题,覆盖方便快捷且成本低。
[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.
