 HERALD
P-P Radio Link Design Software
A PC program for Windows that assists the Radio
Engineer in the design of Point-to-Point Microwave Links and Networks, in
the frequency range from 450 MHz up to 90 GHz
HERALD (HElp for RAdio Link Design) is an easy-to-use yet powerful
tool, covering the gap
between simple spreadsheet computations and sophisticated (high cost)
design suites.
