About the FR1 / FR2 split

3GPP divides 5G NR spectrum into two frequency ranges. FR1 covers 410 MHz to 7.125 GHz and hosts the bulk of commercial deployments — low-band coverage layers on n28, n71 and n8, the mid-band capacity workhorses on n77, n78 and n41, and legacy re-farmed FDD carriers on n1, n3 and n66. FR2 sits in the millimetre-wave region from 24.25 GHz up to 71 GHz and is reserved for TDD bands n257, n258, n260 and n261, where very wide 100–400 MHz channels are available at the cost of far shorter range and much stricter blockage.

Duplex mode is colour-coded: FDD bands have paired uplink and downlink allocations; TDD bands share a single block for both directions via time multiplexing; SDL / SUL bands are supplemental one-way carriers that must be aggregated with a normal carrier.
