多频段室外覆盖室内穿透损耗研究

Study on Multiband Penetration Loss from Outdoor to Indoor

随着移动互联网的发展,用户对无处不在的通信需求越来越强烈,因此,无线通信深度覆盖需求也越来越高。针对传统室外覆盖室内穿透损耗测试方法的局限性提出一种新的测试方法,该方法应用大数据分析的思想,利用室内外大量移动测试数据的直接对比,得出室外覆盖室内的穿透损耗。同时,为支撑LTE FDD/TD-LTE融合组网,本文利用所述方法对FDD 900 MHz/1800 MHz,TDD F频段、D频段分别进行了多处测试,用于指导LTE网络规划指标设计及规划方法研究。

With the development of mobile Internet, the requirements of users for ubiquitous communications are more and more urgent and the requirements for the depth coverage of wireless communications is increasingly high demanded. According to the limitation of the conventional testing method of penetration loss from outdoor to indoor, a novel testing method was proposed. In the method, large amounts of indoor and outdoor mobile tested data were directly compared based on the big data analysis to obtain the penetration loss from outdoor to indoor. In the meantime, in order to support the TD-LTE/LTE FDD integrated networking, the FDD 900 MHz/1800 MHz, TDD F band and D band were tested by means of the proposed method to guide the LTE network planning metrics design and the planning method research.
