EM.CUBE's Propagation.module is a site-specific wave propagation modeling tool that enables engineers to quickly determine how radio waves propagate in a given urban or natural environment. EMAGWARE has refined and transformed the functionality of its EMTerrano product into EM.CUBE's new propagation.module. The integration of EMTerrano into EM.CUBE has also allowed the opportunity to inject powerful new features into this venerable software tool.
The rapid growth of wireless communications along with the high costs associated with the design and deployment of effective wireless infrastructures have created an urgent need for computer aided design tools for communication network planning. Wireless engineers have long been using statistical prediction models based on measurements that often exhibit considerable errors especially in areas having mixed building sizes. Advanced ray tracing solutions like EM.CUBE's, on the other hand, find the dominant propagation paths specific to the site in question. These methods model the physical channel and the mechanisms by which radio signals propagate from transmitters to receivers. EM.CUBE's propagation.module calculates the true signal characteristics at the actual locations using databases of buildings and terrain at a specific site, not those of an average or representative environment.
