While 802.11ah does operate at sub-1GHz, BLE Long Range seems to be 2.4GHz, just with much more robust coding. DECT-NR on 1.9GHz wil be lower in frequency than that and on less shared spectrum. The comparison is not the same everywhere, as the European 868MHz bamd allows much less power (25mW vs. 1000mW) and much less bandwidth (5MHz vs. 25MHz) than USA 915MHz. Similarly the USA 1.9GHz DECT band allows less power (100mW vs. 250mW) and less bandwidth (5channels vs. 10channels) than the European band. So even before meshing DECT-NR has some major advantages over 802.11ah, in Europe.
