Activate the Site Survey
The built-in site survey tool is activated from the Ascom setting menu in the following way:
1. On the handset, go into the Settings > Ascom settings > Wi-Fi.
2. Enter the password 40022 to open the settings.
3. In the opened menu, tap Wi-Fi signal monitor.
4. The site survey tool will be shown in the current screen as an overlay in PIP mode.
If Wi-Fi is disabled, the site survey will display the "Wi-Fi disabled" text. With enabled but not
connected Wi-Fi, the site survey will not show any text or will show symbols.
5. To turn off the site survey, repeat the steps above and press the Back or Home button once the site
survey display has been expanded. Alternatively (any screen), long press the site survey overlay and
drag it down to the Drag down to dismiss tray.
Evaluate the Radio Environment
To evaluate the VoWiFi system RF environment, follow the procedure below:
1. Configure the handset for the Wi-Fi network environment, refer to the Wi-Fi chapter in Configuration
Manual, Ascom Myco 3, TD 93309EN.
2. Open the build-in or third-party Wi-Fi analyzing tool and perform a site survey.
Be sure to walk slowly. Since the value is filtered sudden drops in field strength caused by the
environment, for example walking through a door into a room, will be delayed. Thus, it is
important to walk slowly through the site to cover all weak spots.
Coverage and Roaming Test
The purpose of the test is to verify that the handset is able to roam between different APs without losing
connectivity or experiencing interruptions or distortions to the voice quality. The support engineer makes a
call from a handset that can be physically moved around to another handset in a fixed location and then
physically moves through an Extended Service Set (ESS).
