Remcom Updates Wireless InSite EM Propogation Software

Remcom announced 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.

According to the company, 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.

The 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.

The maximum permissible exposure (MPE) 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.

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.
