UMTS frequency bands vs UARFCN
This tutorial on UMTS covers UMTS frequency bands vs UARFCN.
RF carrier frequency in UMTS is calculated based on UARFCN. UARFCN stands
UTRA Absolute Radio Frequency Channel Number.
In GSM, ARFCN is used to calculate the carrier frequency.
UARFCN calculation formulas are mentioned below.
Uplink: NUL = 5 * (FUL - FUL_Off)
Downlink: NDL = 5 * (FDL - FDL_Off)
FUL_Off and FDL_Off is defined in TS 21.101 standard released by 3GPP,
with this we can obtain following UARFCNs.
| UMTS Frequency band | Carrier Frequency range(MHz) | UARFCN |
|---|---|---|
| Band I | 1922.4-1977.6(FUL), 2112.4-2167.6(FDL) | 9612-9888(UL), 10592-10838(DL) |
| Band II | 1852.4-1907.6(FUL), 1932.4-1987.6(FDL) | 9262-9538(UL), 9662-9938(DL) |
| Band III | 1712.4-1782.6(FUL), 1807.4-1877.6(FDL) | 937-1288(UL), 1162-1513(DL) |
| Band IV | 1712.4-1752.6(FUL), 2112.4-2152.6(FDL) | 1312-1513(UL), 1537-1738(DL) |
| Band V | 826.4-846.6(FUL), 871.4-891.6(FDL) | 4132-4233(UL), 4357-4458(DL) |
| Band VI | 832.4-837.6(FUL), 877.4-882.6(FDL) | 4162-4188(UL), 4387-4413(DL) |
