5G NR Band Finder
Enter a frequency in MHz and see every 5G NR band that covers it, with FR1/FR2, duplex mode and overlapping band matches.
FR1
FR1 covers sub-6 GHz NR frequencies, from roughly 410 MHz to 7.125 GHz. It includes both re-farmed LTE bands (n1, n3, n28) and new mid-band capacity bands (n77, n78, n41).
FR2
FR2 is the mmWave range above 24.25 GHz, offering very high bandwidth over short distances. This finder's band table covers FR1, the range used by the vast majority of commercial 5G networks.
TDD/FDD
Mid-band 5G capacity layers (n77, n78, n41) are almost always TDD, alternating uplink and downlink on one frequency. Low-band 5G (n1, n3, n5, n28) is typically FDD, reusing paired spectrum inherited from LTE.
Overlapping NR bands
n77 (3300-4200 MHz) is a superset of n78 (3300-3800 MHz), so any frequency in that shared range matches both. This finder always returns every matching band, never a single guess, so you can confirm which one your equipment or license actually uses.
Common cellular deployments
n28 and n71 typically carry wide-area outdoor coverage at low band. n77/n78 carry the bulk of 5G capacity in dense areas. The right band for a deployment always depends on the specific spectrum license, not just physical frequency.

Frequently Asked Questions
What 5G band uses 3500 MHz?
3500 MHz sits in NR band n78 (3300-3800 MHz) and is also covered by the wider n77 (3300-4200 MHz). n78 is the primary global 5G mid-band, deployed by most operators for capacity.
What is FR1?
FR1 covers sub-6 GHz NR frequencies, roughly 410 MHz to 7.125 GHz, home to the low-band coverage layers (n28, n71) and mid-band capacity layers (n77, n78) most networks rely on.
What is FR2?
FR2 covers mmWave frequencies above 24.25 GHz, used for very high-capacity, shorter-range 5G. This finder focuses on FR1 bands, which cover the large majority of commercial 5G deployments.
What is TDD vs FDD for 5G?
TDD bands (like n78, n41) share one frequency for uplink and downlink using time slots, common in mid-band 5G. FDD bands (like n1, n3, n28) use separate uplink and downlink frequencies, common in low-band 5G reused from LTE.
Can NR bands overlap?
Yes, n77 (3300-4200 MHz) fully contains n78 (3300-3800 MHz). A frequency inside that overlap is valid for both bands, and this finder lists all of them rather than picking one.
What are common cellular deployments at these frequencies?
Low-band NR (n28, n71) is typically used for wide-area coverage. Mid-band NR (n77, n78) is the main 5G capacity layer in most countries. Band choice always depends on the operator spectrum license in that market.
