I had never heard of either of those two technologies but I would definitely do some googling now, thanks for the tip.
I would rather avoid a 4G hotspot attached to my wheelchair for a couple of reasons, chief among them is the data costs would be really high. If I were to extend my home Wi-Fi network I've already paid for my Internet connection, I'm just making my home Wi-Fi network WAY BIGGER than it was intended to be. :-)
Your links sent me down a rabbit hole of Iot stuff and now I'm super excited about it. Had no idea that lte-m is so widespread.
It's only a matter of time before it's easier and cheaper to get any kind of networked devices onto a carrier network than the users wifi. The implications are kinda scary though: does this mean it's only a matter of time before the majority of personal devices talk to their users with a telco/govement middle man network?
The alternative would be a small battery-powered 4G hotspot like the Huawei E5573CS-322.
