Network as a Service PlayBook Widget: EARFCN Calculator

EARFCN Calculator

This widget computes the EARFCN for an LTE carrier based on its Downlink and Uplink frequencies.
Please fill Uplink and Downlink frequencies squares.

Basics for this widget are addressed on section 2.3 of the RAN LLD Module

1. ENTER UPLINK AND DOWNLINK FREQs (IN MHz)
2. IF FREQS LIE WITHIN MULTIPLE BANDS, ENTER THE BAND NUMBER AT THE POPOUT (SEE CHANNELS AVAILABLES)
3. READ UPLINK AND DOWNLINK EARFCNs RESPECTIVELY

• Uplink Nu = 10 * (FUL - FUL_low) + Noffs-UL, where FUL_low ≤ FUL ≤ FUL_high
• Downlink Nd = 10 * (FDL - FDL_low) + Noffs-UL, where FDL_low ≤ FDL ≤ FDL_high
