If you look carefully on the cell phone, it has "No internet connection" but can still access content hosted on the notebook computer wirelessly.

On a Linux Mint machine I set up an Apache server, created a WiFi hotspot, and put an HTML file on the notebook computer's hard drive. Then I connected my Android cell phone wirelessly to that home server. In a web browser on the cell phone, I entered the IP address of the server and was able to view the content on the home server. My wife's Apple phone also was able to connect wirelessly and download the content. There was no internet connection and no cell phone towers required to do this. It was simply a home network using three wireless devices.

This could serve a useful purpose. A home server could have useful content stored on it. All neighbors within range of that signal could access the web pages, media, books, or other content on that home server. Even without an internet connection or cell phone towers, neighbors could communicate wirelessly, if they are within range of each other. This would be especially useful in apartment buildings, college dorms, on a bus, or in other crowded areas where devices are closer together. People could share content even without a corporation acting as a middle man.
