How is Arfcn calculated in GSM?

The actual frequencies (uplink and downlink) used inside the frequency range are determined by the ARFCN. … Frequency Bands.

EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.

The Absolute Radio Frequency Channel Number (ARFCN) is a unique number given to each radio channel in GSM. The ARFCN can be used to calculate the exact frequency of the radio channel . Within the GSM900 band ARFCN 1 to 124 are used. In the GSM1800 band ARFCN 512 to 885 are used.
