Line of sight networking was obsoleted by WiFi and Bluetooth. What problem does this solve?

The plant using to light to communicate "water me" is cute though, hehe.

It is easier to prevent signal leakage with light.

If you mean this specific solution, then yes - Bluetooth is probably more advanced. If you mean general "line of sight" networking, then no. Laser connections between buildings are doing just fine and provide communication on bigger ranges than customer-grade wireless. There's also no interference between many lasers in the same area. Once calibrated, laser links provide stable (or at least more stable than wifi) quality.
