HERALD is a Sw tool useful in designing point-to-point radio links and networks, with close reference to guidelines and propagation models recommended by ITU-R. It deals with all the basic steps in link design: network topology, terminal site and hop configuration (including passive repeaters and diversity arrangements), link budget, performance predictions (path obstruction and reflection, multipath, rain). A complete interference analysis in a radio network is executed. HERALD uses customized Radio Equipment and Antenna Libraries (Access Format), with easy retrieval procedures.

VisSim/Comm is a software program for modeling and simulation of analog, digital or mixed-mode communication systems at the signal or physical level. VisSim/Comm combines an intuitive drag-and-drop block diagram interface with a powerful time-domain simulation engine that produces fast and accurate solutions for even the most complex communication systems. With VisSim/Comm engineers can simulate and view signal waveforms at any stage of communication system chain.

A comprehensive set of proven communication blocks including signal sources, encoders/decoders, modulators/demodulators, filters, channels, RF components and PLLs makes it easy to build, modify, and maintain complex communication systems. Additionally, VisSim/Comm includes built-in FIR and IIR filter design wizards to simplify and automate the filter design process.

VisSim/Comm also includes the VisSim Viewer, a run-time, view-only version that allows users to freely distribute models to individuals not licensed to use VisSim/Comm.
