Formula & Theory
FR1: 410–7125 MHz, FR2-1: 24250–52600 MHz, FR2-2: 52600–71000 MHz, λ = c / fThis formula is used to calculate antenna parameters for 5g nr frequency range & band classifier.
Overview
Use this 5G NR frequency band calculator to classify any carrier frequency from 410 MHz to 71,000 MHz into 3GPP Frequency Range 1 (Sub-7 GHz) or Frequency Range 2 (mmWave).
Input Guide
Enter Carrier Frequency exactly in the units shown by this 5g nr frequency range & band classifier. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Carrier Frequency — use MHz.
Output Guide
The results describe the calculated 5g nr frequency range & band classifier values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The 5G NR Frequency Range & Band Classifier uses FR1: 410–7125 MHz, FR2-1: 24250–52600 MHz, FR2-2: 52600–71000 MHz, λ = c / f. Supply Carrier Frequency (MHz) in the displayed units, then use the calculated values as the first engineering target for this 5g nr design or analysis.
Design Notes
3GPP TS 38.101 defines two main frequency regimes: FR1 (Sub-6 GHz / Sub-7 GHz) and FR2 (mmWave). Release 17 extended FR2 into FR2-2, opening up spectrum from 52.6 GHz up to 71.0 GHz for high-capacity unlicensed and licensed mmWave links.
Build and Tuning Notes
FR1 frequencies support FDD, TDD, and SUL modes with 15, 30, or 60 kHz Sub-Carrier Spacings. FR2 frequencies operate exclusively in TDD mode using wider 60, 120, 240, 480, or 960 kHz Sub-Carrier Spacings to overcome high phase noise.
Frequently Asked Questions
What is the exact frequency boundary for 5G FR1?
3GPP TS 38.101-1 defines FR1 from 410 MHz to 7,125 MHz (often called Sub-6 GHz or Sub-7 GHz).
What is the difference between FR2-1 and FR2-2 in 5G NR?
FR2-1 covers 24.25 GHz to 52.6 GHz (3GPP Release 15). FR2-2 extends mmWave coverage from 52.6 GHz to 71.0 GHz (3GPP Release 17/18).
Why is there an unassigned spectrum gap between 7.125 GHz and 24.25 GHz?
Frequencies between 7.125 GHz and 24.25 GHz are reserved for legacy satellite, radar, and terrestrial point-to-point links. (Note: 6G research and 3GPP Rel-19 are evaluating upper mid-band 7–24 GHz spectrum).
