Frequency Bands and ARFCN

The following table shows the relationship between frequency band, ARFCN, and frequency.

Frequency Band	Uplink/Downlink Separation	Uplink Frequency Range (Transmit Device = Mobile)	Downlink Frequency Range (Transmit Device = Base)	ARFCN
GSM 450	10 MHz	450.4 to 457.6 MHz	460.4 to 467.6 MHz	259 to 293
GSM 480	10 MHz	478.8 to 486 MHz	488.8 to 496 MHz	306 to 340
GSM 750	30 MHz	747 to 762 MHz	777 to 792 MHz	438 to 511
GSM 850	45 MHz	824 to 849 MHz	869 to 894 MHz	128 to 251
P-GSM 900	45 MHz	890 to 915 MHz	935 to 960 MHz	1 to124
E-GSM 900	45 MHz	880 to 915 MHz	925 to 960 MHz	0 to124 and 975 to 1023
R-GSM 900	45 MHz	876 to 915 MHz	921 to 960 MHz	0 to124 and 955 to 1023
DCS 1800	45 MHz	1710 to 1785 MHz	1805 to 1880 MHz	512 to 885
PCS 1900	45 MHz	1850 to 1910 MHz	1930 to 1990 MHz	512 to 810

The examples below show how the software sets the frequency after you enter the Frequency Band, the ARFCN, and select Mobile or Base as the Transmit Device.

In the figure below, the P-GSM 900 frequency band is selected with Base as the Transmit Device. The corresponding frequency range from the table is 935 to 960 MHz. The entry of 124 forARFCN causes the software to set the frequency at the upper limit of the frequency range for Base (959.8 MHz).

Click the Generate Waveform button to update the frequency setting.

In the example below, the ARFCN is set to 1. The Frequency Band remains set at P-GSM 900 and Transmit Device remains set at Base. When the waveform is generated, the software sets the frequency to the lower limit of the frequency range for Base (935.2 MHz).
