GPS survey with Ekahau – setting up

Intended Audience: Anyone wishing to perform GPS survey using Windows 10, GpsGate and Ekahau Site Survey Pro.

Requirements: Ekahau Site Survey Pro, compatible USB GPS receiver (I am using a Garmin 62s handhled GPS unit), Windows Operating System

Step 1 – Download and install the latest version of GPSGate Splitter

This application is referred to as “GpsGate Splitter” on/by the website.

Latest version: at the time of writing.

I strongly recommend you download the most up-to-date version of this software.

Download Link:

Follow the on-screen instructions to complete the install of Franson GpsGate.

Step 2 – Ensure your USB GPS receiver is recognised by Windows

Plug in your USB GPS

I am using a Garmin 62s handheld GPS unit:

The Garmin unit should be configured with the “Interface” set to “Garmin Spanner”. When I plug the unit into my laptop, the Garmin asks whether or not to enter USB Mass Storage mode, Say NO.

To ensure Windows has correctly identified your GPS receiver and has the appropriate drivers installed, we go to Control Panel > Device Manager

01 Device Manager
This is what we don’t want to see!

This unknown device, is my Garmin GPS unit, but until Windows correctly identifies the connected hardware, we will not be able to get any GPS data into Ekahau.

Fortunately, for me the solution was easy,

02 Update Driver Software..
Right-click on the unknown device, Update Driver Software
03 Search Automatically
Search automatically!

Windows was able to find appropriate drivers.

04 Garmin USB GPS

If Windows does not manage to find the drivers for your specific device, I recommend you check the manufacturers website or start Googling for the drivers specific to your particular brand/model of GPS receiver.

Step 3 – Run GpsGate as administrator

The very first time you launch GpsGate, you should “run as administrator”.

05 Run as administrator

Subsequent manual launches of GpsGate do not need to be “run as administrator”.

Step 4 – Check GpsGate input / output

When I launch GpsGate no window appears, but an icon appears in the system tray. Left-click on the GpsGate icon > Settings

06 GPS receiver running ok
GPS receiver is recognised by GpsGate

Check the “Output” tab

07 Virtual COM port running ok
On the “Output” tab, Virtual COM / Garmin Emulator should read “Running OK!”

If you see an error message, check the appendix at the end of this article.

Step 5 – Launch Ekahau Site Survey Pro

To ensure that GPS data is being received by Ekahau, select the Survey tab and check the “Use GPS” box.

08 co-ordinates with ESS
If everything is working correctly, your current coordinates will appear on the right hand side of the toolbar

Hover the mouse cursor over the warning triangle to view the warning message.

Appendix – Troubleshooting GPS Survey with Ekahau

If co-ordinates do not appear in Ekahau, here are a few things I would try:

  1. Shutdown GpsGate and re-launch the application “as administrator”
  2. Check the version of GpsGate, (Current version is displayed in the title bar of the GpsGate application window). If not the most recent version, download and install the latest and greatest version.
  3. Open the GpsGate window, navigate to the “Output” tab

    Select “Virtual COM 1” within the “Active output” dialog and check the status
  • From my limited time experimenting with GpsGate:
  • [5] Failed to create virtual serial port

    – GpsGate has NOT been “run as administrator”
  • [1275] Failed to create virtual serial port

    – The operating system is 64-bit, some older versions of GpsGate require additional workaround steps to make them work
  • 64-bit workaround (NOT required with the latest version of GpsGate), after some Googling, these two forum threads; need to perform the following:
    • Close Franson GpsGate
    • navigate to the installation folder of Franson GpsGate

      C:\Program Files (x86)\Franson\GpsGate 2.0\x64
    • copy the file “bizVSerialNT.sys” into

    • launch GpsGate “as administrator”

Once Virtual COM1 status reads “Running OK!” we should be able to launch Ekahau

Hopefully, this post has been useful, or at the very lease, NOT a waste of your time.

Thank you for your interest
