Frequency to LTE and 5G Band Finder

Map any RF frequency to its 3GPP band allocations. Essential for spectrum analysis and interference hunting.

FDD vs TDD

FDD uses paired spectrum (separate uplink and downlink ranges). TDD uses unpaired spectrum (one shared range, separated in time). Both LTE and NR matches identify uplink or downlink. SDL/SDO bands provide downlink only; SUL bands provide uplink only.

The versioned catalogue includes 74 LTE and 92 NR entries. Every result opens its own band reference. Browse all LTE bands or all NR bands. A range match does not prove that a channel, bandwidth, device or regional deployment is valid; inspect the band-specific conditions.

Why several LTE bands can overlap at one frequency

A frequency alone does not uniquely identify an LTE band. For example, 1960 MHz lies inside the downlink ranges of both Band 2 (1930–1990 MHz) and Band 25 (1930–1995 MHz). The finder may show other matches too. Select the correct radio technology and direction, then check the deployed band's identity and channel number.

Overlapping allocation ranges do not by themselves prove interference. Actual occupied bandwidth, channel centres, timing, filtering and local spectrum assignments matter. This tool shows range matches; it does not predict adjacent-channel interference or certify a deployment.

LTE EARFCN, 5G NR-ARFCN and UMTS UARFCN

LTE uses EARFCN, 5G NR uses NR-ARFCN, and 3G UMTS uses UARFCN. They use different numbering rules. RF Utility provides an LTE EARFCN converter and a 5G NR-ARFCN converter; it does not currently provide a UMTS UARFCN calculator.

Calculation reference

A range match occurs when f_min ≤ f ≤ f_max.

Variables and units

All frequencies are MHz. FDD uses separate transmit/receive allocations; TDD shares one range in time.

Worked example

1842.5 MHz matches LTE Band 3 downlink and NR n3 downlink.

Assumptions and limitations

Covers 74 LTE and 92 NR band entries with both directions, including satellite and historical references. An allocation match alone does not prove a valid channel, bandwidth, operator deployment or permission to transmit. Every result links to its source and conditions.
