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.
Ad hoc peer-to-peer networks can provide reliable communications in emergency situations where fixed infrastructures, like base stations, may not be available. This example demonstrates Wireless InSite's Transceivers capability.
In this presentation, an example showcasing Wireless InSite's novel diffuse scattering technique is applied to an office environment at 73 GHz and is compared against measurements. The effect of diffuse scattering can clearly be seen on the cross polarized components.
This presentation demonstrates a new predictive tool for simulating Full Dimension Multiple Input, Multiple Output (FD-MIMO) in urban environments. We evaluate a hypothetical small cell base station employing FD-MIMO for cases using different numbers of transmit antennas, then analyze predicted multipath in the environment and compare performance of beamforming techniques for each of the simulated cases.
In this interview from The Mobile Network, Remcom discusses how a new approach to Massive MIMO channel modeling will be key to success of 5G network rollouts and applications.
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.
This webinar demonstrates Wireless InSite’s MIMO simulation capability to predict the multipath and channel characteristics for a Massive MIMO system in an urban small cell. Different beamforming techniques are applied to the simulation results in order to predict the beams to several mobile devices and observe how they change as one device moves along a route through the city.
This webinar demonstrates Wireless InSite’s diffuse scattering capability. An indoor office environment is used to show specific key effects of diffuse scattering, including its impact on complex impulse response and increased cross-polarization of received signals.
This webinar demonstrates the Wireless InSite workflow with a special focus on the new MIMO capability.
This demonstration shows how Wireless InSite meets 3GPP and METIS channel modeling requirements for 5G.
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 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.
This video introduces Wireless InSite’s Floor Plan tools and shows the user how to create and edit an indoor environment. The demonstration includes the placement of walls, doorways, and windows, along with material selection from Wireless InSite’s material database. In addition to the 2D floor plan editor, the video also demonstrates how to make edits within the 3D display.
