Remcom announces major update to wireless InSite EM propagation software

Software/EDA

July 31, 2013

Remcom announces a new version of Wireless InSite®, its electromagnetic propagation software for the analysis of wireless communication systems. This major point release, which updates the product to Release 2.7, provides new capabilities related to statistical modeling of parameter uncertainty, calculation of maximum permissible exposure to EM radiation based on IEEE Standard C95.1-2005, and a new outdoor-to-indoor propagation model for conditions where indoor floor plans are not well known. These new capabilities allow users to predict the impact that unknown conditions of the scenario may have on results, whether for RF propagation analysis or for the new capability to assess radiation hazards. The release also introduces a new version of the accelerated and multi-threaded X3D Ray Model that will run in a CPU mode to support systems that do not have a CUDA-capable GPU, bringing multi-threading and the new advanced modeling capabilities to all Wireless InSite users.

Highlights of the release include:

Parameter Uncertainty
Wireless InSite’s Parameter Uncertainty capability enables the user to define distributions for various project inputs (material properties, frequency, and transmitter input power) in order to assess the impact that these uncertainties could have on calculated outputs. Using a Monte Carlo approach, calculations for the ray paths are evaluated over the parameter distributions to generate the minimum, maximum, mean, median, and standard deviation of received power, path gain, and path loss.

Maximum Permissible Exposure (MPE)
This module provides the ability to calculate MPE values and compare them to the safety thresholds defined by the IEEE Standard C95.1-2005. The user may conduct a hazard assessment and visually display the MPE relevant quantities, as well as their relation to the MPE thresholds.

Modified COST Building Penetration Model: 
The Modified COST Building Penetration Model simulates outdoor-to-indoor propagation when the building's interior floor plan is not known. Wireless InSite’s X3D model uses the interior field values along with two empirically derived parameters to capture average losses from fields’ angles of incidence and interior obstructions within the building. It then returns received power, path loss and path gain at receiver positions within the building.

Culvert Geometry Editor
A new Culvert Geometry Editor facilitates creating simple straight culverts or culverts with a single 45 º or 90º bend. The editor provides control over the culvert’s length, diameter, and the number of sides in the culvert’s circumference. The culvert geometry can then be used to calculate propagation within a tunnel or culvert.

Ryan Ohs, product manager for Wireless InSite, said, “The addition of MPE is important for anyone evaluating potential radiation safety hazards. These users include RF safety personnel at test ranges and government facilities as well as DOD personnel investigating exposure to radar, RF transmitters, or HPM systems. In addition, we’ve added features that are beneficial for all users who need to predict fields or potential RF hazards for scenarios in which some of the parameters are uncertain, allowing them to assess and bound the impact of those uncertainties on the final results.”

About Wireless InSite: Wireless InSite is a suite of 2D and 3D ray-tracing models and high-fidelity EM solvers for the analysis of site-specific radio propagation and wireless communication systems. It provides efficient and accurate predictions of propagation and communication channel characteristics in complex urban, indoor, rural and mixed path environments. Applications range from military defense to commercial communications, including wireless communication links, antenna orientation and coverage, and interference from multiple transmitters.
