Features – Version History

The latest Herald Professional release is 6.5 December 2016

If you are using an older version please contact us for an upgrade.  Full version licence holders (V6) are eligible for a free update.  Annual licence holders with a current valid licence may update for free. Expired annual licence holders may renew their licence through our online store or through the web site from where they purchased Herald Pro.

We now offer academic licences for students and teachers.  Please contact us for more information and to check whether you are eligible.

Changes in last update:


What’s new in HERALD Pro Rel. 6.5 – December 2016

  1. Extension of frequency range up to 90 GHz.
  2. Atmspheric absorption estimate (ITU-R Rec. P.676).
  3. Bug correction in Multipath Occ. Model dialog (no effect on final results).
  4. Rain: estimate of Fade Margin required for given unavailability.
  5. Removal of some limitations in Google *kml file reading (site import).

What’s new in HERALD Pro Rel. 6.4 – June 2015

  1. Herald Help in chm format.
  2. Bug correction in Antenna library management.
  3. Improved support of Google Earth exports.
  4. Brazilian customers: reading ANATEL frequency assignments for interference analysis.

What’s new in HERALD Pro Rel. 6.3 – December 2013

  1. Video and printed output documents can be produced in Portuguese (in addition to previous options for English, Spanish, or Italian)
  2. ITU Rain attenuation model has been updated to the most recent ITU-R Recs. P.530-15 and P.837-6; statistical parameters for rain intensity prediction are now read from ITU-R Databases (files ESARAIN_BETA_v5, ESARAIN_MT_v5, and ESARAIN_PR6_v5, included in the Herald Update kit).
  3. ITU Multipath model has been updated to the most recent ITU-R Rec. P.530-15; terrain roughness data are now read from ITU-R Database (file SaTableWorld.csv, included in the Herald Update kit), instead of being computed from SRTM maps.
  4. Antenna Pointing can be modified by the operator, according to a number of options (in previous releases, antennas were automatically pointed to the other Radio Site position); this new option is useful with sectorial or omni antennas, in particular to design Point-to-Multipoint networks.
  5. Different radio Equipments can be installed at the two Radio Sites (in previous releases, the same Radio Equipment was assumed at both Sites); again, this option can be useful in the design of Point-to-Multipoint networks.
  6. Additional minor improvements refer to display of Google Earth maps, reflection analysis, radio star management, enhancements in output documents (in Hop Report, signal losses are now preceded by a “-” minus sign).
  7. The Help text has been updated accordingly.

What’s new in HERALD Pro Rel. 6.1 – September 2012
1. Import of Path Profiles from ASTER maps (1arcsecond resolution, worldwide coverage, free download), as an alternative to SRTM maps
2. Update of the Rain Unavailability model to the most recent ITU-R Rec. 530-14
3. Improvements in radio star network management
4. Improvements in Google Earth mapping
5. AutoSave function to automatically save the Herald project

What’s new in HERALD Pro Rel. 6.0 – December 2011
1. Revision of Herald data storing procedures in order to comply with Win7 guidelines for system protection
2. Generation of Radio Star networks with a single command
3. Creation of Radio Site sub-sets to ease site management (export to Google Earth; definition of radio stars; …)
4. Improved Google Earth mapping with additional options to customize Radio Network representation as a Google map; user data and comments in pop-up windows, associated to each radio hop
5. Reading Antenna diagrams from ASCII files (according to NSMA standard)

What’s new in HERALD Pro Rel. 5.1 – April 2011
1. Google Earth: Import of Radio Site name and coordinates to Herald site list
2. Google Earth: Export of Radio Network map to be displayed as a Google view
3. Evaluation of ground Reflection coefficients according to ITU-R Rec. P.527
4. Improved use of NASA-SRTM digital elevation maps
5. Update to the most recent version of ITU-R Rec. P.530 and P.526 (rain and multipath models).

What’s new in HERALD Pro Rel. 5.0 – February 2010
1. Crane rain attenuation model (in addition to ITU model) to estimate rain unavailability
2. Estimate of obstruction loss caused by multiple obstacles, according to ITU-R Rec. P.526-10
3. Implementation of Longley-Rice model (ITM) to estimate reliability of radio links below about 3 GHz.
4. Import of radio site data from ASCII files
5. Revision of antenna data input for sectorial and omnidirectional antennas

What’s new in HERALD Pro Rel. 4.2 – June 2008
1. New procedures in setting performance and availability objectives and comparison with predicted results (options for using ITU or North America standards)
2. Related update of performance prediction procedures, equipments data, Radio Section reports
3. Option to use Imperial units (miles, feet, …) instead of metrical units in project documentation
4. Use of Dispersive Fade Margin model (DFM, North America standard), as an alternative to ITU-R Rec. P.530 model, to predict multipath outage in wide-band (frequency selective) digital radio systems
5. New Menu list “Customize” with all user options (Language, Coordinate system, Propagation models; Performance objectives …)
6. Dialog improvements: Hop Configuration (branching loss); Reflection analysis (options in Degradation prediction); Path profile (setting obstacles along a path)

What’s new in HERALD Pro Rel. 4.0 – April 2007
1. Use of SRTM Maps to import path profiles and estimate area roughness (multipath prediction)
2. Use of alternative site coordinate systems (geo coordinates, UTM coordinate, with various Datums)
3. Update of ITU-R Rain model with new parameters for rain attenuation as given in ITU-R Rec. P.837-3
