- A Raspberry Pi 3 Model B+ or a newer model
- A micro SD card with at least 16GB
- WiFiMon Raspberry Pi operating system image (Installation option 1) or Raspberry Pi with installed Raspberry Pi OS (Installation option 2)
Setting up the WHP
There are two options for the WHP installation:
- Installation and configuration from the prepared WiFiMon WHP image (Installation option 1)
- Installation and configuration on the Raspberry Pi with already installed Raspberry Pi OS (Stretch or later) (Installation option 2)
Installation and configurationAnchor Option 1 Option 1
| Option 1 | |
| Option 1 |
The following steps apply for both installation options. WiFiMon users who will use the prepared WHP image (installation option 1) should simply edit the crontab and wireless.py files as discussed in the following. WiFiMon users who will not use the prepared WIFiMon WHP image (installation option 2) should follow the steps 2 up to 4.
Step 1: Write the image to the micro SD card
Follow the instructions at the official Raspberry Pi site. Skip the "Download the image" step and use the WiFiMon Raspberry Pi operating system image instead (download size is approx. 8 GB).

We advise the user to always secure Raspberry Pi by changing the default password.
Step 2: Start the Raspberry Pi
Follow the simple steps below:
...
You should see a red light on the Raspberry Pi and raspberries on the monitor. The WiFiMon Hardware Probe will boot up into a graphical desktop.

Secure the Raspberry Pi by changing the default password. Optionally, you may enable SSH to access the command line of a Raspberry Pi remotely or setup remote desktop. Next, you have to connect to the wireless network you want to measure.

Line 5 of the crontab is related to the streaming of wireless network interface metrics to the WiFiMon Analysis Server (WAS). Optionally, the intervals of the WHP measurements could be altered by appropriately configuring the crontab so that measurement are more or less frequent. The configuration of the crontab config given above sets up 10-minute intervals between the measurements of each test tool in a way in which there are no overlapping measurements.

In /home/pi, you will find the Python script wireless.py. The contents of the script are the following:

That's all! At this point you may (optionally) unplug the keyboard, the mouse and the monitor and let the WHP measure the performance of your wireless network!
