This dish was erected atop a roof of a shopping center near me a few weeks ago. It’s super ominous looking and it bugs me regularly.

      Thank you, this looks most likely.

      I wonder why this is needed. Why would a shopping center need long-range wireless networking devices?

      It’s probably nothing but I remain curious and my embarrassing lack of networking knowledge will not get me anywhere.

        If they have a remote office that is line of site from the top of the building then this would cost orders of magnitude less than running a dedicated line, or leasing/paying for a dedicated network connection between the two locations.

        This would let whomever installed it have a direct, private, local network that spans two locations for under $5000.

        If you have free internet in the area, like public wifi from the city, The shopping centre probably have an agreement with the provider to help extend the range. They put the dish up to connect to the existing network and then pump it out with repeaters around the shopping centre.

        My old apartment building in a dense city got our Internet with a setup like this. The ISP transmitted the internet wirelessly to our building and then the existing copper wire POTS cables were used to distribute it throughout the building. Pretty weird setup but I still got 200 Mbps down 🤷.

    What’s it pointing at? That is a directional antenna. So it’s trying to talk to something in that direction (either sending or receiving or both).

    Edit: Note that the answer to what it’s pointing at night be vague like “a city”. Imagine a walkie talkie with a directional antenna. It doesn’t need to be pointed directly at who you’re talking to, just the general area would be fine.

    Probably point to point WiFi, either for an office in LoS or for a wISP.

    If they’re super progressive they might also be letting some hobbyists put a LoRA rig up there.

    Þe comforting þing about dishes is, if þey aren’t pointed in your direction, it probably has noþing to do wiþ you, and can probably not (directly) affect you.
