LINKPlanner v5.3.1 Now Available

A new release of the LINKPlanner is available from

There is a known issue with the BOM Estimator code when the Link Type is 2+x or 4+0. Please contact us on for a patch if you wish to use this feature.

The key features of 5.3.1 are:

New or changed features

  • PTP 820
    • Added Multiband support to PTP 850E and PTP 820E ESP

Multiband allows an 80 GHz radio as well as either an 18 or 23 GHz radio to share a common antenna. To activate Multiband in LINKPlanner choose the 80 GHz frequency and set the product to either PTP 850E or PTP 820E ESP then choose from the Link Type options listed below. In each case Link A will be an 80 GHz 1+0 link and Link B will be the 18 or 23 GHz link.

  • Multiband 1+0 – In this configuration Link B will also be a 1+0 link and can use either a PTP 820S or PTP 820C radio.
  • Multiband 2+0 Co-Polar (ACCP) – In this configuration Link B will be a 2+0 Co-Polar (ACCP) link using a PTP 820C radio and single polarization antenna
  • Multiband 2+0 Cross-Polar (ACAP) – In this configuration Link B will be a 2+0 Cross-Polar (ACAP) link using a PTP 820C radio and dual polarization antenna
  • Multiband 2+0 XPIC (CCDP) – In this configuration Link B will be a 2+0 XPIC (CCDP) link using a PTP 820C radio and dual polarization antenna
  • Changed default power supply for PTP 820C

The default power supply for PTP 820C is now the same as for PTP 820S (the AC Power Injector 56V). The previous power supply is still available in optional extras. If changing back to the original power supply remember to also remove the Gigabit Surge Suppressor and Power cord and reduce the number of Ethernet Connectors.

  • Obsolete CNT antennas
  • ePMP – Release 4.5 features
    • Added support for 4x4 Omni antenna and omni/split sector MU-MIMO

Please note that this 4x4 Omni antenna pattern does have nulls in it and therefore the performance will change depending on the azimuth angle selected. The grouping of subscribers is also dependent on the orientation of the antenna and subscribers group differently to when using the sector antenna.

  • Added Lower 6 GHz band for ePMP 3000L and Force 300 CSM
  • Added additional RF Elements Horn antennas on the AP

The 40, 50, 70 and 80 degree symmetrical horns and the 30, 60 and 90 degree asymmetric horns have been added to the AP for ePMP 1000, 2000 and 3000L

  • Added 10 MHz bandwidth on Force 300-19R in PTP mode
  • Obsolete ePMP 1000 without sync radios

These radios are used for the ePMP 1000 SM and in PTP when Gb Ethernet Port is set to None.

  • PTP 550
    • Added 10 MHz bandwidth on PTP 550E
  • PTP 670/700
    • Added parent level aggregation page for PTP 700 2+0
    • Added redundant antenna option for PTP 700 2+0

It is now possible to configure a PTP 700 to use a single antenna through a coupler or two antennas per end and to make the choice independently for each end of the link.

  • Allowed PTP 700 2+0 paths to use different cable types and cable losses

The cable type and length can be chosen independently for each radio to connect to the antenna, however to maintain balance on the links it is recommended to design the cables to have similar loss.

  • cnReach
    • Updated 700 MHz EIRP limit to comply with Part 27

This increases the EIRP from 44 dBm to 62.1 dBm

  • General
    • Added different options on setting the SM height in the Viewsheds

The single subscriber height option has been replaced by the following options:





  • Height above ground will use the configured height above ground level for all locations. In the menu this height will be shown as a height AGL, e.g. 10m AGL
  • Height above clutter is only enabled when Use Clutter is selected and the total height for all subscriber locations will be ground height + clutter height + fixed height above clutter. In the menu this height will be abbreviated as AC.
  • Min height above clutter is also only enabled when Use Clutter is selected. In this case both the Height Above Ground and Height Above Clutter can be configured. For each location LINKPlanner will use the height above clutter where that is higher than height above ground. This allows users to set a minimum install height above the ground, for example in rural areas where the clutter height is typically 0 m, but where the install may need to be say 5m above ground level and then increase the height in areas of higher clutter.
  • Added warning to SM downlink receive power if it exceeds maximum limits

The transmit power from the AP is fixed for all subscribers, which means that it is possible for close subscribers especially if a high gain SM antenna is selected to have a receive power at the SM above the recommended operating level for good performance. A warning is now shown at the SM if the receive power is too high.


Bug Fixes

  • Added support for lower throughput requirements

It is now possible to set the Mean IP Required below 5 Mbps and the Min IP Required below 1 Mbps and have it maintained in the project file.

  • Corrected modem quantities in PTP 820G 2x1+0 unit redundancy when TDM is enabled

Increased the modem quantity to two per end when TDM is enabled the same as without TDM

  • Updated PMP 450m sensitivity data, giving improvement in the 3 GHz bands
  • Corrected the PTP 820C HP port allocations in the installation reports
  • Fixed issue causing memory overload in the table views
  • Prevented PMP projects from appearing to be modified after opening
  • Replaced missing rows in Performance Details table for Force 300 products
  • Obsolete Radiowaves 8ft antennas
  • Removed additional brackets from Force 11n SMs in BOM Estimator
  • Corrected PTP 820 remote mount flex waveguides and hanger kit quantities

This affects PTP 820C and PTP 820C HP in 2+2 Co-Polar and 4+0 Cross-Polar and 4+0 XPIC configurations and most PTP 820F configurations when using remote mount antennas.

  • Removed TDD Sync panel in PTP Equipment Templates as it can’t be configured when range is not known
  • Improved warning when requesting viewsheds with invalid user credentials
  • Ensured that ptpprj project files load viewshed color
  • Updated Radio viewshed to use correct SM location height instead of always using ground height.

When using one of the options with height above clutter this may give more covered area than in the previous release.

  • Corrected viewshed label to use band frequency rather than center frequency of band
