n79 – 5G NR Frequency Band – 4500MHz TDD

n79: Introducing 5G NR Frequency Band

CableFree 5G NR Radio Band n79

n79 is a frequency band designated by the 5G NR standard. Note that in 5G, the NR bands are defined with prefix of “n”. When the NR band is overlapping with the 4G LTE band, they share the same band number.

5G Band Name

TD 4500

Duplex Mode


Operating Band (MHz)

4400 to 5000 MHz


693333 to 733333

Supported Channel Bandwidths

40 50 60 80 100 MHz


n79 (TD 4500) is a 5G frequency band.

n79 Coverage

n79 coverage is relatively short to due to the propagation characteristics of the higher band frequencies.

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.
