摘　　要：为了解决TD-LTE专网通信系统实地部署过程中耗费的高人力、高物力和高财力问题,设计完成了专网系统多场景链路预算软件。软件以链路预算流程为基础,依托Okumura-Hata模型、Cost231-Hata模型、海面无线传播模型、漏缆模型和Keenan-Motley室内模型,实现了陆地场景、海面场景、地铁场景、室内场景的全覆盖。用户借助该软件能够准确计算网络的覆盖范围,进而评估无线网络的的覆盖性能,指导基站的建设,为网络规划奠定重要基础。In order to solve such problems as high manpower, high material resources and high financial resources in the field deployment of TD-LTE private network communication system, a multi-scenario link budget software for private network system is designed and completed. The software is based on the link budget process and relies on the Okumura-Hata model, Cost231-Hata model,sea surface wireless propagation model, leaky cable model and Keenan-Motley indoor model to realize the full coverage of land scenes,sea scenes, subway scenes and indoor scenes. With the help of this software, users can accurately calculate the coverage of the network,evaluate the coverage performance of wireless network, and guide the construction of base station, and lay an important foundation for network planning.
