What is EARFCN?

EARFCN (E-UTRA Absolute Radio Frequency Channel Number) is a unique number assigned to each LTE carrier frequency. Instead of using raw frequency values, LTE networks identify channels using EARFCN numbers.

EARFCN is the channel number that represents a specific LTE frequency.

Used in LTE (4G) networks
Maps directly to uplink and downlink frequencies
Defined by 3GPP specifications
Widely used in planning and optimization

Why EARFCN is Important in LTE

EARFCN plays a critical role in radio network operations:

Cell planning and frequency allocation
Drive test log analysis
Interference troubleshooting
LTE optimization and KPI analysis

EARFCN Formula (LTE Frequency Calculation)

Downlink Frequency

F_DL = F_{DL_low} + 0.1 × (N_DL − N_Offs-DL)

Uplink Frequency

F_UL = F_{UL_low} + 0.1 × (N_UL − N_Offs-UL)

N_DL = Downlink EARFCN
N_UL = Uplink EARFCN
Frequency unit = MHz
Channel spacing = 100 kHz

LTE Frequency Bands

Complete LTE operating bands based on 3GPP TS 36.101. Useful for EARFCN calculations, RF planning, and LTE optimization.
