5G NR Base Station Classes | BS Type 1-C, Type 1-H, Type 1-O, Type 2-O

This page describes 5G NR Base Station Classes or types. The 5G NR BS classes include BS Type 1-C, BS Type 1-H, BS Type 1-O and BS Type 2-O.

Introduction:
The 5G NR (New Radio) is the latest wireless cellular standard which follows its predecessor LTE/LTE-A. It follows 3GPP specifications release-15 and beyond. BS (Base Staion) in 5G NR is known as gNB.

5G NR BS are available in following frequency ranges FR1 and FR2. Refer all the frequency channels >> of 5G NR system.

Frequency range Description
FR1 450 to 6000 MHz
FR2 24250 to 52600 MHz

Table-1: BS frequency bands

5G NR Base Station should support following channel bandwidths at different sub carrier spacing.

Following table mentions 5G NR Base Station (BS) or gNB classes.

5G NR BS classes Description
BS Type 1-C NR base station operating at FR1 with requirements set consisting only of conducted requirements defined at individual antenna connectors.
BS Type 1-H NR base station operating at FR1 with a requirement set consisting of conducted requirements defined at individual TAB (Transceiver Array Boundary) connectors and OTA (over the air) requirements defined at RIB (Radiated Interface Boundary).
BS Type 1-O NR base station operating at FR1 with a requirement set consisting only of OTA requirements defined at the RIB.
BS Type 2-O NR base station operating at FR2 with a requirement set consisting only of OTA requirements defined at the RIB.
