From the relatively little I understand the lower the radio frequency the lower the bandwidth but more range it has/can pass through, while conversely the higher frequency the more bandwidth but shorter range/harder to penetrate obstacles (see eg: 5G). LoRa is the former and used for very low bandwidth applications, so not really suitable for browsing websites but has been used for for remote IoT stats, text messaging, etc.

(Fwiw I wasn't the one who downvoted but thought it'd be worth mentioning)

It's not so much about the frequency (though what you say is true), as there's LoRa at 2.4 GHz as well. I'm guessing the one in the article was 868/915 MHz, though.
