Wireless InSite^® Release 2.4 offers many enhancements, including a Communication System Analysis module, improved analysis of wideband signal propagation, modeling of atmospheric ducting effects and plane wave sources for modeling airborne and satellite based transmitters. Another new feature is the recently announced Real Time Module for obtaining very fast physics-based path loss predictions for communication links in urban environments. For the complete list of new features and their benefits, read the New Features List.

The Release 2.4 user interface module runs on the Windows XP and Vista operating systems. The propagation analysis modules run on both Windows and Linux operating systems and can take advantage of multiple processors to reduce the computation time. Complete details can be found in the  User's Manual.

Overview

Wireless InSite allows RF communications engineers to accurately analyze the impact of the physical environment on the performance of wireless communication systems. The software provides a broad range of site-specific predictions of propagation and communication channel characteristics in complex urban, indoor, rural and mixed path environments. Most of these results are derived from accurate solutions to the underlying EM wave propagation problem determined by the UTD (Uniform Theory of Diffraction) and FDTD (Finite Difference Time Domain) methods.

In addition to the basic ray-tracing capability, Wireless InSite can utilize the optional Moving Window and Urban Canyon FDTD propagation models.  Distinct from the ray-based methods, these models simulate propagation by directly solving Maxwell's equations using the Finite-Difference Time-Domain (FDTD) method. Moving Window FDTD is used to simulate propagation of radio waves at UHF and VHF frequencies over irregular terrain. Urban Canyon is intended for high-rise urban environments where the transmitting and receiving antennas are located close to the ground relative to building heights. Wireless InSite's innovative methods provide a powerful new tool in the hands of communication system design engineers.
