China ISP Spectrum Allocation ​

This page provides detailed information about the 4G/5G frequency band allocations for China's major carriers (China Mobile, China Telecom, China Unicom) and China Broadcasting Network (CBN), including common EARFCN/NR-ARFCN values and their corresponding frequency ranges.

About Channel Numbers

  • EARFCN (E-UTRA Absolute Radio Frequency Channel Number): 4G LTE channel number
  • NR-ARFCN (NR Absolute Radio Frequency Channel Number): 5G NR channel number

The center frequency can be calculated from these channel numbers. See Frequency Calculation Formulas at the bottom of this page.

Frequency Calculation Formulas ​

4G LTE EARFCN Calculation ​

For FDD bands, the downlink frequency is calculated as:

$$ F_{DL} = F_{DL,low} + 0.1 \times (EARFCN - N_{offs,DL}) $$

Common band parameters:

BandF_DL_low (MHz)N_offs_DLEARFCN Range
B1211000-599
B3180512001200-1949
B586924002400-2649
B892534503450-3799

For TDD bands:

BandF_low (MHz)N_offsEARFCN Range
B3420103620036200-36349
B3825703775037750-38249
B3918803825038250-38649
B4023003865038650-39649
B4124963965039650-41589

5G NR-ARFCN Calculation ​

According to 3GPP TS 38.104, NR-ARFCN to frequency conversion:

$$ F = F_{REF-Offs} + \Delta F_{Global} \times (N_{REF} - N_{REF-Offs}) $$

Frequency RangeΔF_GlobalF_REF-Offs (MHz)N_REF-OffsNR-ARFCN Range
0-3000 MHz5 kHz000-599999
3000-24250 MHz15 kHz3000600000600000-2016666
24250-100000 MHz60 kHz24250.0820166672016667-3279165

Calculation Example:

For NR-ARFCN 627264:

  • This value falls in the 600000-2016666 range, use the second set of parameters
  • F = 3000 + 0.015 × (627264 - 600000) = 3000 + 408.96 = 3408.96 MHz

5G Spectrum Refarming Progress ​

As of 2025, Chinese carriers are refarming the following bands for 5G:

CarrierOriginal BandRefarmed BandStatus
China MobileB38 (2.6G 4G)n41 (2.6G 5G)Mostly completed
China MobileB34 (2.0G 4G)n34 (2.0G 5G)In progress (2025)
