You're correct. The key thing to understand is when people talk about "internet" and "connectivity" in the context of LoRa, we're talking about very small packets (like a few bytes), transmitted using "chirp encoding" which is a clever hack to send small packets reliably over long distances). You're not going to be watching youtube on this, and probably not even checking email. Previous discussion about this: https://www.amazon.com/Amazon-Sidewalk/b?node=21328123011 https://www.amazon.com/Amazon-Sidewalk/b?node=21328123011 via https://news.ycombinator.com/item?id=27115809&p=2 https://news.ycombinator.com/item?id=27115809&p=2 The wireless tech behind this is called LoRa (Long Range) radio https://enterpriseiotinsights.com/20201208/channels/news/lora-alliance-semtech-in-talks-with-amazon-to-switch-sidewalk-over-to-lorawan https://enterpriseiotinsights.com/20201208/channels/news/lor... Most use cases I have head about base don LoRa radio are for tracking (clients send GPS coordinates once every 10 mins), transmitted packets are caught by one (or more?) gateway, which FWDs the packet to a server on the internet. I think ACKs can be sent back from the server, but not required.
