CTS 328: Simple 3D Designs and Validation with Hamina (Sponsored)

Clear To Send: Wireless Network Engineering

Rowell and Jussi discussed the use of 3D modeling for Wi-Fi design and validation using Hamina. Jussi demonstrated the tool they use, showing how it can predict signal behavior in a warehouse environment.

They also discussed the importance of 3D modeling for validating project details like shelf heights and the construction of walls.

There’s immense value of this tool for collaboration with non-Wi-Fi professionals.

3D modeling is useful in a stadium environment using slopes and raised floors. Jussi explained how the simplicity Hamina allows for complex designs. The importance of the material of the raised floor was also highlighted.

Jussi goes into how Hamina will be used to perform a validation survey. At Hamina, they developed a mobile app and hardware for this purpose, which stores data locally and uploads it to the cloud when an internet connection is available. The device, which can host four Wi-Fi 6E adapters and includes a USB-C connector for data, supports optional spectrum analysis. Jussi confirmed the device’s battery life is not affected by its size and it can last half a day before needing a charge.

Going into the various survey methods, specifically Point Survey, Line Survey, and Continuous Survey. Jussi explained that Point Survey is a simple method that collects data intermittently, whereas Line Survey collects data continuously but provides a bit more relaxation time between clicks.

As far as functionality goes, Jussi confirmed that the app continuously saves measurements to prevent data loss and can detect the vendor of the Access Point automatically. The app’s analysis features include primary and secondary coverage, channel interference, and the ability to view data for specific frequencies or SSIDs.
