n48: Introducing 5G NR Frequency Band
n48 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 3500
Duplex Mode
TDD
Operating Band (MHz)
3550 to 3700 MHz
NR-ARFCN
Supported Channel Bandwidths
10 15 20 40 50 60 80 90 100 MHz
Summary:
n48 (TD 3500) is a 5G frequency band.
n48 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.
