n261 · 28 GHz mmWave
n261 is a 3GPP 5G NR band (28 GHz mmWave), TDD duplex, uplink 27500–28350 MHz and downlink 27500–28350 MHz. It is millimetre wave: huge bandwidth and very short range, mainly for hotspot capacity. Of the 155 networks we check, 1 use it (United States).12

What it means for IoT devices
- n261 adds capacity in United States: it raises city speeds, but coverage comes from the low bands.
- This is a TDD band: FDD-only modules cannot use it.
Our dongles (MF833V, Dongle 400, F40) do not support n261.
