Characterizing the properties of higher frequencies for 5G applications

拟议的项目将研究杂乱室内环境中的无线电传播，其中短程5G无线通信链路可以在2到30 GHz之间的频率上实现。一个选定的，真实世界，室内，环境将使用软件建模，软件射线跟踪将被用来预测窄带和宽带特性的无线电链路之间的发射机/接收机对位于选定的环境根据商定的概率密度函数。然后，将报告感兴趣的无线电信道特性的累积概率分布，这些特性将包括：传输损耗、多径延迟窗口和均方根延迟扩展，以及主路径信号分量以及次路径（用于分集）和多径信号分量的接收和离开角度。 然后，将使用矢量网络分析仪来测量数据，从这些数据中可以估计样本无线信道特性，以便与射线跟踪结果进行比较和校准。 最终报告将包括射线跟踪和测量结果的比较，以及2 GHz-30 GHz范围内几个不同中心频率下的无线信道特性的比较。

The proposed project will study radio propagation in cluttered indoor environments where short range 5G wireless communication links could be implemented at frequencies between 2 and 30 GHz. A selected, real-world, indoor, environment will be modelled using software, and software ray tracing will be used to predict both the narrowband and the wideband characteristics of radio links between transmitter/receiver pairs located within the selected environment in accordance with an agreed-upon probability density function. Cumulative probability distributions will then be reported for radio channel characteristics of interest, which will include: transmission loss, multipath delay window, and rms delay spread, as well as angles of reception and departure for both primary path signal components, as well as secondary path (for diversity) and multipath signal components. A vector network analyzer will then be used to measure data from which sample wireless channel characteristics can be estimated for comparison with, and calibration of, the ray tracing results. The final report will include comparisons of ray tracing & measurement results, as well as a comparison of wireless channel characteristics at several different centre frequencies within the 2 GHz-30 GHz range.
