The Microcell/Indoor Module, an add-on module to EDX® SignalPro® and Signal®, provides for the planning of in-building networks along with micro-cell networks in the dense urban or campus environments. The Microcell/Indoor module includes 2D/3D ray tracing for in-depth analysis of the in-building and outdoor micro-cell environments as well as the EDX Simplified Model(ESIM) for fast what-if scenario modeling. The MIM allows for point studies, route studies and area-wide coverage studies enabling flexibility in the design process.
