This example demonstrates how a custom beamforming table can be used to model downlink data rates from three MIMO base stations for 5G New Radio in a section of Boston.

The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth. The geometry for the house was imported from a CAD file and a flat terrain was placed underneath the house.

The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.

In this example the signal transmission between a massive MIMO base station and a mobile device located in downtown Rosslyn is analyzed using Wireless InSite’s MIMO capability.

In this paper, results are presented of propagation experiments conducted to verify the accuracy of a novel ray-optical scattering model for EES.  

Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of the body shaped as a vertical strip. Although extensively validated in controlled laboratory experiments, the model does not scale to realistic 3D scenarios with many, randomly oriented bodies, on which multipath signals can be incident from any direction, not just normal to the strip. To address this, in this article we investigate computational electromagnetic methods based on raytracing.

The safe rollout of new or enhanced 5G services using C-band spectrum near airports in 2022-2023 will require realistic modeling of radio propagation to mitigate potential interference with legacy radar altimeters which remain in operation as of summer 2022. In this whitepaper, we use Wireless InSite to provide a realistic assessment of radar altimeter interference due to emissions from 5G base stations along a landing approach to runway 27L of Chicago O’Hare International Airport.

Drawing on expertise from the wireless industry, including carriers, operators, device manufacturers, and providers of wireless simulation tools, the IWPC created a comprehensive report that identifies the key features, obstacles, and potential solutions for deployment of mmWave for 5G.

This webinar demonstrates the strengths of Remcom’s XFdtd and Wireless InSite for designing and simulating smart home devices, analyzing propagation and beamforming capabilities, and assessing throughput performance of the devices via MIMO techniques.

Learn about WaveFarer's new features for automotive and indoor radar applications, including diffuse scattering from rough surfaces such as roads and the ability to transmit through walls, windows, and more. Remcom will demonstrate these and other new capabilities using a sample drive scenario as well as an indoor mmWave sensor scenario.

This short video clip demonstrates how Wireless InSite models engineered electromagnetic surfaces (EES) and compares coverage improvement with diffuser and grating EES placements on a glass window or a wall.

Tarun Chawla, Remcom's Director of Business Development, was a guest on the Sciencei Podcast. Tarun discussed the revolutionary technologies in wireless communications that have been developed during the past decades.

Using WaveFarer's included scripts, users can leverage Remcom's XGtd path viewer to generate ray path animations. This clip demonstrates the capability by showing backscatter in an indoor scenario, visualizing how waves diffract through doorways and penetrate walls.

In this video tutorial series, we walk through a step-by-step outdoor propagation analysis using Wireless InSite MIMO.
