GSM ARFCN to frequency calculator | ARFCN to frequency conversion
This page GSM ARFCN to frequency conversion provides GSM ARFCN to frequency calculator. It mentions formula or equation used for GSM ARFCN to frequency calculation. The table below mentions GSM ARFCN, downlink frequency equation and corresponding uplink frequency equation for various GSM frequency bands viz. 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 basically number to represent the pair frequencies in the downlink and also in the uplink.
| 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 |
