EARFCN E-UTRA Absolute Radio Frequency Channel Number
Since the E-UTRA operates with more flexibility than UMTS , a updated method of identifying the centre carrier frequencies is used. The carrier frequency in the uplink and downlink is designated by the EARFCN (E-UTRA Absolute Radio Frequency Channel Number) in the range 0 - 65535. The channel raster is 100KHz for all bands, which means that the carrier centre frequency must be an integer multiple of 100KHz. The relation between EARFCN and the carrier frequency in MHz for the downlink/uplink is given by an equation and associated table of frequency bands.
