Dalam jaringan selular GSM, sebuah absolute radio-frequency channel number (ARFCN) adalah kode yang menentukan sepasang carrier radio dan channel yang digunakan untuk pemancar dan penerima di Um interface, satu untuk sinyal uplink dan satu untuk sinyal downlink. ARFCN di definisikan di GSM Specification 05.05 Section 2.
Setiap ARFCN mempunyai bandwidth 270.833 kHz. ARFCN menggunakan spasi kanal 200 kHz di band GSM. Spasi Uplink-downlink biasanya 45 atau 50 MHz.
Beda frekuensi (ARFCN) digunakan untuk komponen frequency-based dari GSMs multiple access scheme (FDMA — frequency-division multiple access). Bersama dengan komponen time-based (TDMA — time division multiple access) maka kanal fisik di definisikan dengan memilih thARFCN and a certain time slot. Note not to confuse this physical channel with the logical channels (e.g. BCH — Broadcast Control Channel) that are time-multiplexed onto it under the rules of GSM Specification 05.03.
