Within the spectrum allocated for cellular mobile communications, the radio channels are identified by ARFCN. If the system is operating in FDD (Frequency Division Duplex) mode then the channel number is associated with both the uplink and downlink radio channels. Within the GSM900 spectrum ARFCN 1 to 124 are used. In GSM1800 , ARFCN 512 to 885 are used and in GSM1900 ARFCN 512 to 810 are used.
