How is Arfcn calculated in GSM?

The frequency calculator lets you quickly find the frequency, given wavelength, and either the velocity or period . Table of contents: Frequency definition and the frequency formula. Frequency equation from the wavelength.

The actual frequencies (uplink and downlink) used inside the frequency range are determined by the ARFCN. … Frequency Bands. GSM 850T-GSM810ARFCN128 through 251350-425Uplink (UL) Formula (MHz)FUL(n) = 824.2 + 0.2*(n-128)FUL(n) = 806 + .2*(n-350)Downlink (DL) Formula (MHz)FDL(n) = FUL(n)+45FDL(n) = FUL(n)+45Frequency Bands – Keysight RFMW Sitemap rfmw.em.keysight.com › rfcomms › refdocs › gsm › gen_bse_cell_band

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.
