RFGSM ARFCN to Frequency Conversion and Calculator
Advertisement
This page provides a GSM ARFCN to frequency calculator and explains the ARFCN to frequency conversion process.
It includes the formulas used for GSM ARFCN to frequency calculation.
The table below details GSM ARFCN, downlink frequency equations, and corresponding uplink frequency equations for various GSM frequency bands. These include GSM 450, GSM 480, GSM 750, GSM 850, GSM 900 (P-GSM, E-GSM, GSM-R), DCS 1800, and PCS 1900.
In GSM, ARFCN stands for Absolute Radio Frequency Channel Number. It is a number that represents paired frequencies for both downlink and uplink communication.
GSM Frequency Bands and ARFCN Equations
| GSM Band | ARFCN (N) | Uplink Frequency Equation (FUL) | Downlink Frequency Equation |
|---|---|---|---|
| GSM 450 | 259-293 | 450.6 + 0.2 * (N - 259) | FUL(N) + 10 |
| GSM 480 | 306-340 | 479 + 0.2 * (N - 306) | FUL(N) + 10 |
| GSM 750 | 438-511 | 747.2 + 0.2 * (N - 438) | FUL(N) + 30 |
| GSM 850 | 128-251 | 824.2 + 0.2 * (N - 128) | FUL(N) + 45 |
| P-GSM | 1-124 | 890 + 0.2 * N | FUL(N) + 45 |
| E-GSM | 975-1023 | 890 + 0.2 * (N - 1024) | FUL(N) + 45 |
| GSM-R | 955-1023 | 890 + 0.2 * (N - 1024) | FUL(N) + 45 |
| DCS 1800 | 512-885 | 1710.2 + 0.2 * (N - 512) | FUL(N) + 95 |
| PCS 1900 | 512-810 | 1850.2 + 0.2 * (N - 512) | FUL(N) + 80 |
