Lora is different from the others, in that it is for low-data-long-range. All those others are to connect a device to a local network. Lora is to connect to a remote network.
DECT (which I last saw in devices that I was programming in 2005), zigbee and 802.11 are all local network mediums.
802.11ac maxes out at maybe 60-80m, zigbee maxes out at around 80m and DECT (last I used it) maxed out at maybe 100m.
Lora still works up to 15000m LoS.
802.11ah, not 802.11ac.
good catch :-)
In respect of 802.11ah, it's still under 1000m, outdoors, IIRC. Great for the use-case of covering your factory in sensors, not so for the use-cases that LoRa is intended for.
