Duplex Mode
SDL
Operating Band (MHz)
1432 to 1517 MHz

n75: Overview of Band
n75 (DL 1500+ MHz) is a 5G frequency band for Supplimentary Downlink applications.
n75 coverage is moderate to long due to the propagation characteristics of the mid band frequencies.
5G Equipment for Band n75
High quality equipment for this band is available from numerous vendors. An example of a Remote Radio Head (RRH) for this band is shown here:

General Information about 5G Bands
5G NR (New Radio) has been developed to operate in two distinct bands; sub-6 GHz (3GPP 38.104-5.2.1 FR1), and mmWave (3GPP 38.104-5.2.2 FR2). Despite actually running into the 7 GHz band, FR1 continues to be commonly referred to as the “Sub-6 GHz” band.
- FR1: 410 to 7125 MHz
- FR2: 24250 to 52600 MHz
Each band may operate in either FDD or TDD duplex mode. A band may be a supplementary downlink-only (SDL) or uplink-only (SUL) band used to provide additional capacity in the respective direction.
5G Bands are also classified as SA – (Stand Alone), meaning they can operate totally independent on 4G LTE networks, or NSA (Non Stand Alone), which requires the data call to be established over 4G LTE with the 5G carrier then added as a secondary layer.
5G NR uses four different Subcarrier Spacing (SCS) modes; 15, 30, and 60 kHz for sub-6 GHz (FR1) bands; 60 and 120 kHz for mmWave (FR2) bands. Channel bandwidths vary based on SCS, with many only supporting a 5 MHz channel width with an SCS of 15 kHz.
