n66 · 1700/2100 Extended AWS
n66 is a 3GPP 5G NR band (1700/2100 Extended AWS), FDD duplex, uplink 1710–1780 MHz and downlink 2110–2200 MHz. It is a capacity layer: wide and fast, with shorter reach than the low bands. Of the 155 networks we check, 4 use it (United States, Canada).12

What it means for IoT devices
- n66 adds capacity in United States, Canada: it raises city speeds, but coverage comes from the low bands.
Our dongles (MF833V, Dongle 400, F40) do not support n66.
