1. Launch the AirAccessHS GUI
2. Right click on the Node-B icon and select 'Configure Node-B' from the menu appearing
3. Select your desired band and enter the channel number in the 'TX Channel number' box. The exact DL frequency will be calculated based on the formula specified in 3GPP 25.101 section 5.4.3
Examples for band I, II & V:
Band I:
UARFCN (UL) = 5*(ULFreq) UARFCN (UL) range 9612 to 9888
ULFreq=UARFCN (UL) / 5
UARFCN (DL) = 5*(DLFreq) UARFCN (UL) range 10562 to 10838
DLFreq = UARFCN (DL) / 5
Band II:
UARFCN (UL) = 5*(ULFreq) UARFCN (UL) range 9262 to 9538
UARFCN (DL) = 5*(DLFreq) UARFCN (DL) range 9662 to 9938
Band V:
UARFCN (UL) = 5*(ULFreq) UARFCN (UL) range 4132 to 4233
UARFCN (DL) = 5*(DLFreq) UARFCN (DL) range 4357 to 4458
