LINKPlanner v5.6.8 Now Available

A new release of the LINKPlanner is available from the download site.

The key features of 5.6.8 are:

cnWave 5G Fixed

  • Added high level Mu-MIMO throughput results, grouping and spatial multiplexing gain

On the AP the Performance Summary continues to show the SISO (Mu-MIMO Disabled) performance for the usual long term availability (configured on the PMP Links and typically 99%), as in previous releases. The PMP Links performance data also reflects the base SISO performance.

The Mu-MIMO performance is shown in a pop-up report by clicking on the “Mu-MIMO Report” option in the AP Performance Summary section.


This report shows the percentage usage of each group size and the comparison of the SISO Performance from the main AP Performance Summary with the Mu-MIMO Performance in typical dry conditions. The Spatial Multiplexing Gain shown is the ratio improvement of the Mu-MIMO over the SISO throughput.

Note that the Mu-MIMO performance will degrade during rain events and therefore the Mu-MIMO rates do not represent throughput rates that can be guaranteed long term for typical or higher availabilities. Instead they reflect the higher performance that can be expected during stable dry conditions.

  • Updated sensitivity values and increased throughput rates

Release 3 of the software has improved the throughput rates and added differentiation of sensitivity based on polarization, with horizontal polarization having improved sensitivity compared to vertical. There are small changes in the vertical sensitivity as well.

60 GHz cnWave

  • Added Asymmetric TDD for PTP links

PTP links can now choose between 7 different DL/UL ratios from 75/25 to 25/75. Note that when different radio products are used at each end of the link the throughput in both directions is constrained to the lower of the two products. The V1000 is further constrained by the Gigabit Ethernet line limit which reduces the difference between the two directions in the higher MCS.

  • Updated throughput rates for both PTP and PMP

The throughput rates have been updated to Layer 2 UDP one way rates and show improvement for all the CN products, with different rates for each device, but a reduction in throughput for the V5000.

  • Added Bridge in a Box parts to the BOM for V1000 and V2000 links

When a PTP link has either V1000 or V2000 at both ends of the link the BOM automatically adds the Bridge in a Box single kit part number, which provides a paired set of radios for easier installation. If the Bridge in a Box kit is not required it can be replaced with the part number for the individual radios using the Optional Extras (remember to increase the quantity to 2 to include a radio for each end of the link).


  • Retired Force 300-13 and Force 200
  • Added 11 Deg RF Elements Ultrahorn Antenna

PTP 820/850

  • Added new bundled PTP 850C radios and license key part numbers

These new PTP 850C part numbers include 5 of the most common license keys:

  • N000082K167 PTP 820/850 Act.Key - 10GE port Qty 1
  • N000082L027 PTP 820C/850C Act.Key - 2nd Core Activation Qty 1
  • N000082L048 PTP 820/850 Act.Key - MC-ABC, per Tx Chan Qty 2
  • N000082L056 PTP 820/850 Act.Key - XPIC, per Tx Chan Qty 2
  • N000082L126 PTP 820/850 Act.Key - Capacity 650M with ACM Enabled, Per Tx Chan Qty 2

They are automatically added in LINKPlanner for 2+0 XPIC or 4+0 XPIC links when the Ethernet Configuration is set to Single Ethernet (MC-ABC) or L1 Link Bonding and the bandwidth is between 50 and 80 MHz.

Bundled PTP 850C radios are available in 6, 11 and 18 GHz frequency bands only.

The unbundled radio part numbers and the license keys are all available in optional extras if the bundled radios are not required. The bundled radio part numbers are also available in optional extras for other configurations, remember if adding them manually to remove the license keys as well.

  • Updated capacity license keys

PTP 850C now has a 1.6G Capacity license key replacing the previous 2G license key. PTP 820E/850E no longer support a 1G capacity license key, the minimum license key for the 80 GHz radios is now 2.5G.

  • Updated PTP 820/850 sensitivity values

There are small changes to a number of the PTP 820 sensitivity values and up to 1.5 dB reduction in the PTP 850C sensitivity values.


  • Added support for XE3-4TN

To select the XE3-4TN in the WiFi Estimates choose Outdoor with Connectorized as the Antenna Option. As this is a connectorized radio there are various antenna options to choose from for both the 4x4 and 2x2 radios. Please complete the Antenna Selection choices for each radio.


  • Retired e430H, e500, e501S, e502S, e505 and ePMP 1000 Hotspot
  • Updated part numbers for XE3-4 and XV2-2 for new product revision


  • Added cnMaestro-X and Cambium Care Advanced Upgrade parts automatically to the BOM for WiFi 6 radios, cnMatrix Switches, cnWave 5G Fixed and cnWave 60 GHz (cnMaestro-X only)


  • Added Crown Castle towers to the online map (between releases)

Sites are only available in the United States and Puerto Rico. To display or hide the Tower Sites tick or untick the options in the online map display menu.


To view information about a site click on the site and a pop-up window will display the key information about the site.


To add a network site click on the “Create network site here” link and the site will automatically be populated into the network site list.

  • Automatically populate tower email with asset identifiers

When you select the Email link from the pop-up information, the email subject line contains the Asset ID and Asset Name.

Bug Fixes

  • Allow the user to create short links (>= 1m)
  • Fixed issues in the PTP Performance Details tables when modulation modes are restricted and remote product is changed
  • Replaced Maximum Obstruction row with Fresnel Zone Clearance in PTP and PMP Installation reports

The Fresnel Zone Clearance parameter shows the minimum clearance between the edge of the first Fresnel Zone and the closest point on the profile, which could be ground level, clutter or obstruction. The Maximum Obstruction previously shown only included added obstructions and the obstruction could be located further away from the Fresnel Zone than the ground level in another part of the path, so is not as useful in terms of identifying clearance along the path.

  • Corrected issue with PTP 820/850 Link C of 4+0 not updating FSPL and Gaseous Absorption Loss on band change
  • Prevent the cable selection from appearing when the product does not support it.
  • Added warning message for PTP 670/700 when there is no RF cable added to the BOM
