Google Network Planner for Tarana

Intended Audience & Abstract

This document is intended for use by engineers interested in designing and deploying Tarana Gigabit products. It is assumed that the reader has a good working knowledge of RF, fixed wireless access, and networking concepts.

This document describes guidelines for using Google Network Planner to design broadband wireless access with Tarana Gigabit products. This is intended to be a starting point for new Tarana deployments.

Google Network Planner is an accurate, fast, easy-to-use tool that is integrated with Google geospatial data for highly accurate (1 meter resolution) visualization. This includes street as well as 3D modeling of terrain, trees, and buildings. Google Cloud compute power runs advanced RF propagation (ray tracing) models, individual link analysis, and heat maps based on real-world data that is constantly maintained and updated.

Tarana recommends the use of Google Network Planner where available to achieve accurate, high quality results.

NOTE: A companion zip file is also provided that contains resource files described in this document. This file is available in the resources library on the Tarana G1 portal:

Configuring Your First Tarana Network

Google Network Planner is a powerful tool that can provide fast, accurate results. Before using it with Tarana equipment, some initial set up is required. Specifically, the following steps must occur:

  • Upload Tarana antenna files
  • Create and map sites, cells, and sectors
  • Define frequencies and bands
  • Configure heat map settings to match Tarana specifications for received signal strength (RSSI)

Logging In

To log into Google Network Planner, open a browser and enter the URL: Click login to enter your credentials for the planner.

Adding Antenna Files

To accurately model a Tarana Gigabit product, antenna files must be loaded into the planner. These files are available from the Tarana G1 portal: To add the files, click the View Antennas icon in the lefthand navigation pane.

View available antennas

Once on the Antennas page, click, hold, and drag the antenna files onto the page to upload them to the planner. Click Upload to continue.

Drag and drop antenna files into the planner

Upload antenna files

Once the files are uploaded, confirm they appear on the left-hand side of the screen.

Working with Projects

To modify the settings for a project, click the gear icon in the lower left-hand corner of the screen.

Modify project settings

Figure 9: Modify project settings

When planning for a 5 GHz network, the Network Type should be set to Fixed Wireless. For CBRS, set Network Type to Mobility Macro. Specific frequencies (bands) are configured in the Bands portion of the settings.

Configuring network type and band

More detailed configuration is also available. The image below shows the steps to create a custom configuration for four 40 MHz-wide channels starting at 5725 MHz. It also sets the RN antenna height to 5 meters above ground level (AGL) and 1 meter above the roofline. The Tarana_RN_5GHz_R0 antenna file is used in this example.

Site, Cell, and Sector Creation (Bulk uploads)

Once a project has been modified to the correct frequency settings, then sites, cells, and individual sectors can be created within the project. The easiest way to do this is with a bulk upload via a CSV file. The image below shows an example of what this file looks like. Note that this example is for a single 5 GHz cell with four BN sectors. The example CSV file can be expanded to include additional 5 GHz cells and sectors at this site (using a different AGL or band) or for additional sites, azimuths, etc.

Bulk upload of new sites, cells, and sectors

Once the CSV file has been created, it must be imported into the planner. To do this, click Import at the top of the screen. Click Computer to upload the file from your computer’s file system.

Importing a CSV file

Alternatively, the CSV file may also be dragged and dropped onto the map screen.

Two options for uploading a CSV file

Figure 15: Two options for uploading a CSV file

Once the CSV file has been uploaded, the user is prompted to verify the import process. This provides a chance to confirm that the entries in the CSV file are being interpreted correctly. To verify the upload process ensure the following is true:

  • The left-most column is all green checked circles
  • The channel and band rows have no annotations next to them
  • There are no question mark bubbles next to any row

Verify CSV file upload

Figure 16: Verify CSV file upload

If everything looks correct, click the Upload button in the top right-hand corner to proceed. You will see a message that the sites are uploading. The amount of time this takes will be determined by the number of sites.

Sites uploading

Figure 17: Sites uploading

As sites are uploaded, they will appear on the map.

Mapped site

Create Ray Tracing/Propagation Mapping

Once sites have been uploaded to the planner, the next step is to initiate a study. A study is when Google Network Planner creates ray tracing and propagation mapping for each uploaded site. To start this process, click Run all study layers from the map.

Once the study is initiated, the blue Run all study layers button will display a “Computing …” message until the study is complete.

Coverage Options

When a study completes, coverage display options are available for selection. To view options, click the View overlays icon on the left-hand side of the map screen and then click Coverage.

Planner coverage options

Creating a Custom Coverage Heat Map

Google Network Planner allows for customizing heat maps for received power. To create a custom heat map, make sure Received power has been selected on the map.

Note: for accurate results, these values must be edited to reflect Tarana-specific values.

Hover the mouse over the Received Power legend in the upper right and click Edit.

Open heat chart legend settings

In the Intervals section, click Custom to display the current mapping of received power to colors and modify as desired.

Edit (sync) RSSI values
