InfiPLANNER: Link Planning Tool


"Point-to-Multipoint" Links

PtMP mode toolbar includes 3 sections:

  1. Base station parameters.
  2. Base station sectors parameters.
  3. Subscriber terminals parameters.

However, unlike PtP mode, the toolbar has a hierarchical structure due to the fact that each base station has many sectors and each sector has many connected subscriber terminals. Thus, if you go to the toolbar to configure the base station, you will find the list of its sectors. After selecting a sector, its parameters and list of subscriber terminals will be available.

PtMP planning

The PtMP mode is similar to the PtP, but has a number of features:

  1. Only geo-located mode is available.
  2. Base stations sectors configuration is performed first of all. Then subscriber terminals are added and connection with a particular sector is established.
  3. Access to the various interface functions is performed via the context menu of the point on the map.

Base station

Each base station (BS) is the sectors aggregation. Each BS can include up to 6 sectors.

The base station coordinates can be determined on the map by pressing the left mouse button in the proposed location and selecting "Add base station" in the context menu or pressing "2".


There is also an opportunity to search the area on the map by city name, street name, company name, house number, etc. In order to do this, use the search form located at the top of the working space.

The subsequent control of the point is performed through the special context menu available via click on the appropriate object. The menu includes the following functions (from left to right):

  1. The conversion from BS to CPE.
  2. Proceeding to toolbar for further base station parameters configuration.
  3. New base station sector creation .
  4. BS movement on the map.
  5. BS deletion.

Sectors should be created for each base station. Each sector should be oriented in azimuth and elevation angle. In order to add a new sector, press the corresponding button in the BS context menu. Each sector is represented on the map by the radiation pattern with an angle equal to the antenna radiation angle.


Sector antenna radiation pattern is presented conditionally. The main lobe maximum level is also conditional and does not determine the sector real energy potential. Thus, the directional diagram reflected on the map is intended for visual representation of the antenna radiation direction.

Once the sector has been added, it is necessary to clarify its orientation by azimuth and elevation angle.

  1. Azimuth can be changed directly on the map - it is necessary to capture the sector with the mouse and move it to the desired position. However, the map does not have the ability to orient by the elevation angle.
  2. For a more accurate orientation you must select the appropriate BS and sector in the toolbar. After that, a schematic diagram with azimuth and elevation angle will appear at the bottom of the working space. Here you can set the angles with accuracy up to 0.1 degree.

Wireless link parameters, device model, antenna height must be defined for each sector. These can be done from the sector settings toolbar and are similar to link setting in the PtP mode.

Subscriber terminal

Subscriber terminal coordinates are also determined on the map by pressing the left mouse button in the proposed location and selecting "Add subscriber" in the context menu or pressing "1".


In case the subscriber terminal is placed on the map in the area of the sector antenna radiation pattern, its addition is performed by the right mouse button. However, as mentioned above, the radiation pattern is conditional, the actual coverage is much larger.

The subscriber terminal management is similar to BS and performed through the context menu with the following functions:

  1. Conversion from CPE to BS.
  2. Proceeding to toolbar for further subscriber terminal parameters configuration.
  3. Wireless link with BS sector creation.
  4. CPE movement on the map.
  5. CPE deletion.

Wireless link creation is performed manually, regardless of which sector the subscriber terminal is in. In the context menu select the connection creation function, then move the mouse cursor to the BS sector coverage area and click the left button - the connection will be created. You can also move the cursor directly to the BS, in this case the CPE will be connected to the sector in which it is visible.

Subscriber terminal configuration can be performed after connection had been created. In PtMP mode CPE characteristics are inherited from the connected BS sector, so you only have to select the device model and antenna height. The path profile is also available at the bottom of the working space.

The color of the connection line between CPE and BS sector displays the overlapping of the first Fresnel zone:

  • Green - 0-40%.
  • Yellow - 40-60%.
  • Red - 60-100%.


The overlapping is not determined automatically, therefore, the connection line will be colored only when the connection is selected.


The mast pictogram is displayed for each CPE point.  If it is displayed without radio signals, it means that the CPE configuration is not completed. If the radio signal is present, then the CPEs are configured and you can review the estimation results.



Estimation results

All BS connections

All base station wireless links and specific BS sector view is available in PtMP mode. Unlike viewing links on the map, here you can see them in the list with the following information:

  1. BS and CPE coordinates.
  2. Path profile.
  3. Proceeding to link settings and estimation results.

In order to go to the view use "All links" button above the toolbar.

How to read the estimation results

In order to go to the estimation results use the "Result" button above the toolbar. 

The results are presented in summary and detail forms, similar to PtP mode. The summary report allows you to make an overall estimation of the planning link. It includes the following information:

  1. Links parameters and device models for each point.
  2. Modulation scheme and link characteristics for maximum availability.
  3. Modulation scheme and link characteristics for maximum throughput.


Link "Sector BS - CPE" characteristics estimation is performed without taking into account the sector connection with other subscribers. So, the maximum throughput is estimated for the situation when the sector connection to the CPE is the only one.
