Uhhhh. I'd take a look at LoRaWAN or SigFox technology, but that needs appropriate support in your IoT stuff.
The alternative would be a small battery-powered 4G hotspot like the Huawei E5573CS-322.

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. :-)
Espressif also have a shorter distance but lower power option that uses WiFi tech called ESP-Now that is worth looking at: http://espressif.com/en/products/software/esp-now/overview
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?
