The global UMTS bands are clear as Band 1, 8 or Band 2, 5, but LTE bands are much more complex. Band 3 is reportedly the most widely used band for LTE deployment. The reasons that network operators deploy 1800MHz LTE network are obvious: good coverage, and the Rules of Thumb for Duplex Filters • Avoid Bandwidth > 4% of center frequency –At 600MHz, like to keep filter bandwidth <24MHz Rules of Thumb for Duplex Filters • Avoid Duplex gap < 1% –7MHz gap at 700MHz, 26MHz gap at 2.6GHz • Figure of Merit (bandwidth/duplex gap) < 4 • Distance to nearest interfererDistance to nearest interferer Do you want to use 2 external antennas for LTE and need space diversity? This video tells you how far apart to mount the antennas.Product Website: Difference 5G NR and 4G LTE. The studies of 5G NR (New Radio) in 3GPP started in 2015 and later became the first NR specifications in Release 15 in 2018 focusing on the use cases eMBB (enhanced Mobile Broadband) and URLLC (Ultra-Reliable and Low Latency Communication). channel spacing (width) options, @ 12.5kHz, @ 25 kHz and @ 150 kHz. With SATELLINE-EASy product family products, including the previously mentioned models, the RF frequency can be set in 6.25 kHz steps @ 12.5 kHz and @ 25 kHz channel spacing (width).

B2 (1900) is Band Duplex spacing of 45 MHz is used. In some countries the GSM-900 band has been extended to cover a larger frequency range. This 'extended GSM', E-GSM, to testing both 700 MHz LTE and P25 digital LMR networks.
Both DL and UL bands have a width and a gap isolated between them. The download link bandwidth plus the gap is equal to duplex spacing. Numerous regional

The selection of the subcarrier spacing in an OFDM-based system needs to carefully balance overhead from the cyclic prefix against sensitivity to Doppler spread/shift and other types of frequency errors and inaccuracies.
