基于WCDMA室内覆盖的研究与分析.docVIP

. . .. .. . .. 【摘要】： 随着移动通信的日益普及,以及我国通信行业3G时代的全面到来,3G网络建设正在如火如荼的进行。在城市范围内,建筑物内的话务密度不断上升,室内的话务占总话务的比例日益趋高,且数据业务绝大多数都会在室内发生,网络覆盖、容量、质量、效益已经成为运营商获取竞争优势的关键因素。但目前,室内覆盖仍是3G网络覆盖的一个薄弱环节,仅仅依靠室外宏蜂窝基站的覆盖已经无法满足容量及通信质量的要求。本文通过实例,探讨了针对大型重要建筑进行3G室内覆盖的理论与实践,对实际工作有一定借鉴意义。 在论文的撰写过程中,作者收集了大量有关3G室内无线覆盖技术与应用、规划设计的文献。通过阐述了现阶段3G市场运营情况,提出了进行3G室内覆盖的必要性和紧迫性,并分析了河南联通目前阶段3G室内覆盖的整体情况和存在问题。论文从室内覆盖系统的组成入手,重点从工程角度对室内覆盖系统设计技术指标要求、传播损耗分析、频率分配与编号计划要求、工程建设原则等内容进行了分析和阐述。在对WCDMA室内覆盖的一般理论进行了探讨的同时,本文重点针对GSM与WCDMA共享室内覆盖系统的可行性进行了分析,在此基础上,以XX办公楼为案例,根据本案特点,结合相关系统建设原则、技术要求和设计规范,选择合适的室内覆盖组网方式,在实践中参与设计建设工程工作,并对工程系统进行了测试和优化. 关键词； 3G 网络覆盖 质量 效益 Summary With the increasing popularity of mobile communications, as well as 3G era of China communication industry, 3G network construction is like a raging fire of. Within the city limits, traffic density buildings rise, indoor traffic accounted for the total traffic increasingly high proportion, and data services, the majority will be in indoor, network coverage, capacity, quality, efficiency has become the key operators to obtain a competitive advantage factor. But at present, the indoor coverage is still a weak link in 3Gnetwork coverage, relying solely on the outdoor macro cell base stations coverage has been unable to meet the capacity and communication quality requirements. This paper, discusses the theory and practice of 3G indoor coverage for large and important buildings, has certain reference significance to the practical work.In the writing process, the author has collected a large number of documents about 3G technology and application, indoor wireless coverage planning and design. Through the present market operation of 3G, put forward the necessity and urgency of the 3G indoor coverage, and analysis of HENAN UNICOM, the overall situation at present stage of 3G indoor coverage and problems.This paper from the indoor coverage system from the engineering point of view, focus on indoor coverage design technical index requirements of the system, the propagati
