Assessing the Effectiveness of the Ray Tracing Model in Planning MIMO Systems

It is important to consider the properties and parameters of the communication channels when planning wireless networks. For systems with MIMO (Multiple-Input-Multiple-Output) this task becomes much more complex. To predict the parameters of the MIMO channel, it is necessary to obtain a reliable estimate of the channel matrix. There are many MIMO models that can be used to estimate this matrix, but there is much less information about how and which models to use when planning networks. This article aims to fill in these gaps, starting with a ray-tracing model. To verify the developed model, experimental studies were conducted on the example of an indoor network.
