Formula & Theory
Wavelength (m) = 299.792458 / Frequency (MHz)This formula is used to calculate antenna parameters for 5g nr ntn frequency bands calculator.
Overview
Use this 5G NR NTN frequency band calculator to determine signal wavelength and classify satellite carrier frequencies across 3GPP Release 17/18 Non-Terrestrial Network specifications (TS 38.101-5) and standard ITU RF bands.
Input Guide
Enter NTN Carrier Frequency exactly in the units shown by this 5g nr ntn frequency bands. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- NTN Carrier Frequency — use MHz.
Output Guide
The results describe the calculated 5g nr ntn frequency bands values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The 5G NR NTN Frequency Bands uses Wavelength (m) = 299.792458 / Frequency (MHz). Supply NTN Carrier Frequency (MHz) in the displayed units, then use the calculated values as the first engineering target for this 5g nr design or analysis.
Design Notes
3GPP TS 38.101-5 defines dedicated NTN operating bands including Band n255 (L-Band MSS), Band n256 (S-Band MSS), and Band n254 (Ka-Band satellite). Unpaired frequency gaps between uplink and downlink blocks are reserved for guard bands and duplex separation.
Build and Tuning Notes
L-band (n255) and S-band (n256) operating frequencies are preferred for Direct-to-Cell / Mobile Satellite Services due to lower free-space path loss and favorable propagation through foliage compared to millimeter-wave frequencies.
Frequently Asked Questions
What are the exact frequency boundaries for 3GPP Band n255?
3GPP TS 38.101-5 defines Band n255 (L-Band MSS) with downlink frequencies from 1525 MHz to 1559 MHz and uplink frequencies from 1626.5 MHz to 1660.5 MHz.
What are the exact frequency boundaries for 3GPP Band n256?
3GPP TS 38.101-5 defines Band n256 (S-Band MSS) with downlink frequencies from 2170 MHz to 2200 MHz and uplink frequencies from 1980 MHz to 2010 MHz.
How is 3GPP Band n254 allocated in Ka-band?
3GPP Band n254 allocates specific Ka-band satellite sub-blocks (typically 17.7–20.2 GHz downlink and 27.5–30.0 GHz uplink) for high-throughput fixed satellite terminals and feeder links.
