    The problem with laser communication is that it doesn’t take much rain, snow or fog to block the signal.

      Similar “free-space optics” systems have been tested since the late 1990s, but past attempts were limited by weather conditions and fragile alignment systems. Taara claims its devices overcome many of those limitations with improved beam tracking and more resilient design.

      They claim they’ve overcome that hurdle though, as per the article.

        Yes, but the article is literally nothing without that information.

        The only interesting thing about a new approach to laser internet is if they’ve solved the critical issue holding it back.

        Okay, photo taken (by Gabriele Barni) from 17.1177 km (claimed metric kilometers) straight distance to the buildings:
        .

        You can imagine how wobbly the image was.

        How to compensate it? Wide, powerful beam? Gonna be blinded by an invisible light?

        Quote from the video:

        This is as simple as a digital camera with a laser pointer.
