Instantly convert an EARFCN to frequency (or a frequency back to EARFCN) for any LTE band. Automatic band detection, downlink & uplink frequency, and duplex mode — accurate to 3GPP TS 36.101.
📡 3GPP TS 36.101 · 100 kHz rasterTip: enter a DL or UL EARFCN — the calculator detects the band and direction automatically.
EARFCN (E-UTRA Absolute Radio Frequency Channel Number) is the integer that identifies an LTE carrier's centre frequency on a 100 kHz raster. Each band has a low-edge frequency and an EARFCN offset from 3GPP TS 36.101:
For TDD bands the uplink and downlink share the same EARFCN range. The calculator above applies the correct per-band parameters automatically.
| Band | Mode | DL low (MHz) | DL EARFCN | UL low (MHz) | UL EARFCN |

Based on 3GPP TS 36.101 Table 5.7.3-1 (common E-UTRA operating bands).
