Herald 3. 1 Radio Link Design Software. [CD Rom]

HERALD (HElp for RAdio Link Design) is a PC program for Windows that assists the radio engineer in the design of point-to-point (multi-hop) microwave links and networks, working in the frequency range from 0.4 to 58 GHz. HERALD 3.1 can be used by radio communications technicians and engineers as a practical tool for quick design of microwave links. HERALD can also be used as a training tool for graduate students or in short courses to show and test how propagation phenomena affect microwave link performance and how radio link engineering rules can be implemented. The HERALD design process is based on well-established design guidelines. Starting from basic hop configuration and link budget, reliable propagation models are applied to deal with the anomalous propagation events of rain, multipath, obstructions, and reflections. Close reference is made to recommendations of the ITU-R, the Radio branch of the International Telecommunications Union, formerly the CC
