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 :


*  Import of SRTM (NASA) terrain maps, and of ASTER (NASA/METI, Japan) maps


*  Interface to Google Earth to import / export network topology


*  Update to the most recent ITU-R Recs (P.530, P.838, P.527 ...)


*  Comparison of predicted performance with ITU-R or North America performance objectives


*  Reading Antenna diagrams from NSMA (ASCII) files


*  Crane rain attenuation model (in addition to ITU-R model)

HERALD también habla Espanol   -   HERALD também fala Português

Choice of output document language (English, Spanish, Portuguese, or Italian)



HERALD key benefits:


*  Easy-to-use approach to the design of p-p (multi-hop) mw links and networks
