LINKPlanner V4.3.4 Release Now Available

A new release of the LINKPlanner is available from

The key feature of V4.3.4 is:

Bug Fixes

  • Fixed error with rule formatting for 1+1 and 2+0 links

The key features of V4.3.3 are:

New or changed features

  • New Feature - Availability calculations for PMP Link Performance and ability to define Required Availability
    • Updated the Subscriber Module Link Performance to give similar capabilities as the PTP link, allowing the user to define a minimum availability requirement for the existing minimum modulation mode requirement. SMs which don’t meet these requirements will not be incorporated into the Performance Summary at the Access Point.
    • The predicted availability for each modulation mode and the estimated receive time in mode are shown in the Performance Details. The user can choose between using the ITU-R availability model or the Vigants-Barnett model, which can be changed in the Project Properties. The same model is used for both PTP and PMP links.
    • The default Min Required Availability is configured to 99.9%, this may result in some existing marginal links, which were shown as good but had very small fade margins and hence low availability, now failing to meet this default level. This will primarily affect links where the Min Mod Mode Required was set above the default of x1 QPSK MIMO-A.
  • New Feature - PMP Link Formatting Rules
  • PMP/PTP 450i
    • Updated BOM with additional parts and added more to Optional Extras
      • Modified lightning protection options and added Cat5E cables and grounding to PTP links and the AP.
      • Added additional cables, connectors, installation tools etc. to the optional extras for PTP, AP and SM.
    • Added Industry Canada part numbers
      • Existing projects which were configured with the Canadian regulation will show a change in the BOM to give the appropriate Industry Canada part number instead of the Global part number. It is not possible to configure a DES option with the Industry Canada part number.
    • Removed Preliminary from Brazil and Mexico for PTP 450i
  • PTP 650
    • Removed Mid Capacity option (all Mid Capacity users can now upgrade for free to Full).
      • When opening a project which previously contained links configured to Mid Capacity, they will have now been automatically upgraded to Full. This will change the BOM slightly to show a Lite to Full Capacity upgrade key, instead of the previous Mid to Full Capacity key. It is not necessary to purchase any different keys.
  • PTP 700
    • Updated transmit powers and sensitivity values, this will show a degradation on predicted performance for most links from the previous version.
    • Added Industry Canada part numbers
    • Removed Preliminary from FCC countries for 4.5 and 4.9 GHz
  • PTP 820
    • Updated 1+1 BOM for PTP 820C and PTP 820S to remove PoE and add Optical Fibre support
      • Note that this changes the BOM for 1+1 links for PTP 820C and PTP 820S compared with earlier versions of LINKPlanner
    • Added additional 3ft antennas to APAC and EMEA region
    • Added 60 MHz bandwidth to Lower 6 GHz FCC for 2+0 ACAP and ACCP
    • Added Warranty part numbers to Optional Extras
  • Obsoleted PTP 250m 500 and PTP 600 products (except at 4.5 and 4.8 GHz)
    • These products are no longer available for order and will not be available in the PTP BOM Estimator.

Bug Fixes

  • Fixed error when calculating cable lengths in the BOM, which was over-predicting the amount of cable required in some cases
    • The error was doubling the length of the cable on the remote end of the link, which depending on the height of the remote end may have result in an extra cable drum or a larger size cable drum being selected.
  • Differentiate between PMP azimuth and tilt angle error indication when bearing is out of range
    • If the azimuth is shown as out of range, the SM will either need to be connected to a different AP, or the azimuth angle of the AP antenna will need to be changed to bring the SM into the coverage area of the SM.
    • If the tilt angle is shown as out of range and the antenna tilt is more than 30° uptilt, then the SM is below the main antenna beam of the AP. Increasing the height of the SM is likely to bring it back into the main pattern.
  • Add additional explanatory notes to BOM items for PTP-SYNC for PTP 650 and PTP 700 and PoE Injector for PTP 820C and updated other notes on the BOM
  • Prevent the "Test profile service" from returning successful when username or password are incorrect
