The LTE standards have very little to say about the actual frequencies used for the LTE carriers. However in practice it is necessary to restrict the locations of the carrier centres to standardisation purposes.

It is assumed that within each supported band, LTE carriers exist on a 100kHz raster or grid.. In this way the frequency of the carrier frequency, i.e. the centre frequency of the radio channel can be expressed as m . 100 kHz, where is an integer.

To provide a means of identifying the different channels available a schme known as the EARFCN has been adopted.

## LTE EARFCN

LTE EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number. EARFCN number is within range 0 to 65535 .

${F}_{\mathrm{downlink}}={\mathrm{FDL}}_{\mathrm{Low}}+0.1\left(\mathrm{NDL}-{\mathrm{NDL}}_{\mathrm{Offset}}\right)$

${F}_{\mathrm{uplink}}={\mathrm{FUL}}_{\mathrm{Low}}+0.1\left(\mathrm{NUL}-{\mathrm{NUL}}_{\mathrm{Offset}}\right)$

Where:
NDL = downlink EARFCN
NUL = uplink EARFCN
NDLoffset = offset used to calculate downlink EARFCN
NULoffset = offset used to calculate uplink EARFCN

## LTE EARFCN channel / band chart

To provide a view of the EARFCN channel calculations, the table below provides a good indication of the ranges for many of the LTE frequency bands.

It can be seen that the downlink EARFCN starts at 0 and the Uplink starts at 18000.

You are wrong. Enter we'll discuss it. Write to me in PM.

Normul, I have been looking for it for a long time! thanks to all...

I would write you a couple of gentle ones here, but I will refrain. Education does not allow)))
