摘要:

海域数据通信需求随着沿海渔业、海上旅游业发展变得日益迫切。对近海覆盖的业务特点、覆盖规划难点、覆盖优化技术与方法以及实际应用场景进行分析研究,提出综合采用 TD-LTE 系统特殊参数配置、优化海面无线传播链路预算、优化海面覆盖基站站址规划以及覆盖增强等技术。提出的优化方法在上川岛和下川岛进行了实际应用。仿真结果和实测数据表明,TD-LTE网络覆盖优化方法的实施,明显提高了网络覆盖率和通信服务质量。

关键词: 近海无线覆盖, TD-LTE, 链路预算, 覆盖增强

Abstract:

With the development of coastal fisheries and marine tourism,the demand for wireless coverage on offshore is becoming more and more urgent.Based on the analysis on the characteristics of the mobile communication business,the difficulties of offshore coverage planning,coverage optimization techniques for the actual application scenarios of coastal areas,a TD-LTE network coverage optimization method which made comprehensive use of the following technologies including special TD-LTE system parameter configuration,optimization of wireless communication link budget,optimization of the base station site planning and coverage enhancement technologies was proposed.The proposed optimization method was practically implemented in the Shangchuan Island and Xiachuan Island.The simulation results and measured data in the project field show that the implementation of TD-LTE network coverage optimization method has obviously improved the network coverage rate and communication service quality.

Key words: wireless coverage on offshore, TD-LTE, link budget, coverage enhancement
