Why is this part of the 5G spec?
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.
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.
Range of DECT-2020 NR+ is comparable to Bluetooth Low Energy Long Range, which is plenty for a lot of applications but not in the same class as LoRa. But it's much higher bandwidth than LoRa and purportedly has determistic low latency, at least sufficient for audio, and they're marketing it for mission-critical and safety-critical applications.
