 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.
Main Functions :
 Site/Hop Configuration;
Link Budget; Path Profile Analysis (clearance, reflections);
Multipath
Outage; Rain Unavailability;
Interference
analysis;
Passive
repeaters;
One-click
access to Background Theory.
Significant
Features :
