Enabling Accurate Ray-Tracing Predictions for 5G Communication Channels

在私人和公共空间、室内和室外规划和安装无线系统主要依赖于测量和经验模型。然而，下一代通信系统的出现和物联网（IoT）的普及，创造了一个前所未有的复杂性的无线生态系统。此外，考虑到加拿大人在大流行时期面临的挑战，很难夸大智能设计工具在医院，学校，养老院和其他公共场所的无线通信，传感和监控系统中的重要性。无线系统提供符合社交距离规则的非接触式监测，但代价是向其他系统添加干扰信号，并导致封闭空间中弱势群体的辐射暴露。 该项目将产生高保真和计算效率高的仿真技术，用于对现有、新兴和未来无线通信系统（包括第五代（5G）及以后的通信系统）在复杂环境中的电磁波传播进行建模。这样的技术可以预测由发射机系统在给定环境中产生的信号电平。它们可用于优化网络接入点的位置，评估来自和朝向相邻系统的干扰，评估用户暴露于电磁辐射的情况以及执行网络性能研究。该项目是基于多伦多大学的一个研究小组与iBwave（一家致力于改善建筑物内无线网络设计的加拿大公司）之间的伙伴关系，该研究小组在无线通信系统的传播建模方面有着长期的记录。

Planning and installation of wireless systems in private and public spaces, indoor and outdoor, has primarily relied on measurements and empirical models. However, the emergence of next-generation communication systems and the proliferation of the Internet of Things (IoT), create a wireless ecosystem of unprecedented complexity. Moreover, considering the present challenges that Canadians are facing at the time of a pandemic, it is hard to overstate the importance of intelligent design tools for wireless communication, sensing and monitoring systems in hospitals, schools, retirement homes and other public spaces. Wireless systems offer contact-less monitoring that is compatible with social distancing rules, at the cost of adding interfering signals to other systems and contributing to the radiation exposure of vulnerable groups in confined spaces. This project will produce high-fidelity and computationally efficient simulation techniques for modeling electromagnetic wave propagation in complex environments for existing, emerging and future wireless communication systems, including communication systems of fifth generation (5G) and beyond. Such techniques can predict the signal levels created by a system of transmitters in a given environment. They can be used to optimize the position of network access points, assess interference from and towards neighboring systems, evaluate user exposure to electromagnetic radiation and perform network performance studies. The project is based on a partnership between a University of Toronto research group with a long track record in propagation modeling for wireless communication systems, with iBwave, a Canadian company that is dedicated to improving in-building wireless network design.
