在线计算ARFCN和频率比较方便，推荐几个网页工具
1. http://niviuk.free.fr/ （元老站，貌似需要科学方式才能登陆，飘过~）
2. https://itectec.com/3gpp-arfcn-frequency-converter/ (同时计算GSM/UMTS/LTE/5G)

计算公式如下
5G NR-ARFCN Frequency calculation (38.104)
FREF = FREF-Offs + ΔFGlobal (NREF – NREF-Offs)

LTE E-ARFCN Frequency calculation (36.101)
FDL = FDL_low + 0.1(NDL – NOffs-DL)
FUL = FUL_low + 0.1(NUL – NOffs-UL)

UMTS U-ARFCN Frequency calculation (25.101, 25.102)
FDL = FDL_Offset + 0.2(NDL)
FDL = FUL_Offset + 0.2(NUL)

GSM ARFCN Frequency calculation (45.001)
FDL = FDL_Offset + 0.2(NDL – NOffs-DL)
FUL = FUL_Offset + 0.2(NUL– NOffs-UL)
