Moving vehicle or aircraft
Tower placement in urban environments
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.
Modern antennas utilize MIMO technology in order to meet consumer demands for high data rates. As such, throughput is a required design metric when evaluating one antenna design versus another and simulating device performance in a realistic scenario.
This presentation demonstrates a new predictive capability for simulating massive MIMO antennas and beamforming in dense urban propagation environments. Remcom's unique approach allows us to predict the signal-to-interference-plus-noise ratio (SINR) at specific device locations and the actual physical beams formed using these techniques, including unintentional distortions caused by pilot contamination.
To keep up with rising demand and new technologies, the wireless industry is researching a wide array of solutions for 5G, including Massive MIMO. Remcom’s Wireless InSite provides an efficient method to predict channel characteristics for large-array MIMO antennas in complex multipath environments.
This presentation demonstrates how the 3D ray tracing code in Wireless InSite can accurately predict received power coverage even in a multi-room environment containing many walls and different materials types. In order to verify the accuracy of the code, the floor plan of Remcom’s business offices was modeled in the software with a WiFi antenna and a third party tool was used to create a coverage plot of the received power throughout several of the suites.
In this short video from IMS 2018, Remcom's product marketing manager, Jeff Barney, describes the process of simulating the antenna element, modeling the channel propagation, and calculating the throughput modulation.
Remcom performed a study using Wireless InSite's MIMO capability to generate the complex channel matrices for several mobile devices in an urban scene. We then extracted these results and applied two standard beamforming algorithms (using mathematical analysis tools) to visualize beamforming in motion.
This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out.
This video expands a basic floor plan design into a six-story office building. Wireless InSite’s duplication tools make it easy to add levels and floors to the model. In addition, the creation of stairwells and a central glass atrium with a peaked roof are shown.
