Remcom’s Wireless InSite Real Time Module provides Wireless InSite^® with a very rapid propagation capability for urban environments. Using deterministic models, the RT Module produces higher fidelity results than empirical techniques but at greatly reduced computation times compared to full physics-based models.

How Wireless InSite Real Time Works

The RT Module is available as a feature in Wireless InSite, and takes advantage of Wireless InSite’s powerful geometry processing capability. Given the location of a transmitter and receiver, the RT Module determines the relevant geometry between them and performs a rapid computation of path loss. Loss results are returned in milliseconds, depending upon the propagation model, the size and complexity of the urban environment, and the locations of the transmitter and receiver. These almost instant computation times allow for coverage of large areas, or for near-real-time simulations of transmitter and receiver networks.

The RT Module also allows user-defined objects to be placed into the urban “scene” and their effects on the electromagnetic environment subsequently integrated into the propagation computation. This allows the user to simulate the effect of vehicles and other moving objects in the results.

Wireless InSite Real Time Deterministic Models

Remcom’s VPUP (Vertical Plane Urban Propagation) model improves on several limitations of the conventional empirical methods. VPUP considers propagation in the vertical plane, and allows arbitrary base and mobile station heights, corrects the acknowledged analytically errant expressions, and offers several other significant analytical improvements over empirical models.

Triple Path Geodesic is a Remcom-developed deterministic model designed to enhance vertical plane urban calculations. It combines the vertical plane computation of VPUP with a computation in a lateral slant plane (the plane perpendicular to the vertical which also contains both the transmitter and receiver). The energy traveling in this slant plane is combined with the vertical, producing a final path loss.

Wireless InSite Real Time as an API

For application developers who wish to develop their own graphical user interfaces and visualization tools, or who wish to integrate the Real Time module’s capability into an existing application, the RT Module is available as a library with a C++ API, which can operate independent of Wireless InSite.
