5G NR Frequency Explorer
Interactive spectrum map of 5G NR operating bands per 3GPP TS 38.104. Toggle between FR1 (sub-7 GHz) and FR2 (mmWave), hover any band to inspect its DL / UL ranges, bandwidth options and duplex mode.
Hover a band rectangle above to inspect its DL / UL ranges, bandwidth and duplex.

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.

How to use this tool
- Choose FR1 or FR2. Switch the view between sub-7 GHz (FR1) and mmWave (FR2).
- Scan the spectrum map. See how the bands are laid out and where they overlap.
- Hover a band. Read its DL/UL frequencies, bandwidth and duplex for the band you care about.
Frequently asked questions
- What does the NR frequency explorer show?
- It draws the 5G NR bands on a spectrum map so you can see where each one sits and how they line up. Switch between FR1 (sub-7 GHz) and FR2 (mmWave) and hover any band to read its DL/UL ranges, channel bandwidth and duplex, all based on TS 38.104.
- Why do n77 and n78 overlap on the map?
- n78 (3.3–3.8 GHz) is a subset of the wider n77 (3.3–4.2 GHz), so they share the lower part of C-band. The explorer makes this visible, which helps explain why an operator on 3.5 GHz might report n77 or n78 depending on how the band is configured.
- Where is the boundary between FR1 and FR2?
- FR1 covers roughly 410 MHz up to 7125 MHz, and FR2 covers the mmWave range from about 24.25 GHz upward (n257/n258/n260/n261). The gap between them is not allocated to NR bands, which is why the two views are kept separate.
