Supplementary Downlink ( SDL ) and Supplementary Uplink ( SUL ) are modes that allow only downlink or uplink in those bands . SDL and SUL are meant to provide additional capacity. In practice, industry looks at 5G spectrum in terms of low-band (600-700 kHz), mid-band (3-5 GHz) and high-band (26-100 GHz).

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.23 Nis 2020
Read moreWhat band is 3500 MHz?
n78 (3500 MHz), or commonly referred to as the 3.5 GHz 5G band, or C-band 5G , is the most commonly tested and deployed 5G frequency. The n78 band’s popularity is due to its relatively common availability, with lower cellular spectrum already in use by 3G and 4G networks.
Read moreWhat is DL Earfcn in LTE?
EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.
Read moreWhat is DL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies. Also each band is marked by LTE release number where it was defined.

A signal is said to be band-limited if the amplitude of its spectrum goes to zero for all frequencies beyond some threshold called the cutoff frequency .
