C-band

n1 is a FR1 5G NR Band . It follows Frequency Division Duplexing (FDD) mode and the separate uplink and downlink bands allow for simultaneous transmission on two frequencies. The bands have a separation between them called the duplex spacing.

LTE bands are discrete slabs of frequencies that are used for telecommunications. So, for example, LTE Band 1 is stated to have a frequency of 2100 MHz (megahertz), but it actually uses frequencies between 1920 and 1980 MHz to uplink data and frequencies between 2110 and 2170 MHz to downlink data .

FR1 (4.1 GHz to 7.125 GHz) band of frequencies are used for carrying most of the traditional cellular mobile communications traffic, while the FR2 (24.25 GHz to 52.6 GHz) band of frequencies are focused on short-range, high data rate capabilities.

5G is the fifth generation of wireless technology and NR stands for a new radio interface and radio access technology for cellular networks —a physical connection method for radio based communication. Other kinds of radio access technologies include Bluetooth, Wi-Fi and 4G LTE.

5G cellular, or 5G NR, supports two frequency ranges, FR1, from 410 MHz to 7125 MHz , and FR2 from 24.45 GHz to 52.6 GHz. The FR1 range, also referred to as “Sub-6,” generally overlaps LTE cellular frequencies.
