This article describes the different classes or types of 5G NR Base Stations (BS), including BS Type 1-C, BS Type 1-H, BS Type 1-O, and BS Type 2-O.
Introduction to 5G NR and Base Stations
5G NR (New Radio) is the latest wireless cellular standard, succeeding LTE/LTE-A. It adheres to 3GPP specifications from Release 15 onwards. In 5G NR, the Base Station (BS) is referred to as a gNB. These 5G NR BS operate in two frequency ranges: FR1 and FR2. (../../assets/5G-NR-BS-Channel-Bandwidths.jpg).
Table 1: Frequency Ranges
| Frequency range | Description |
|---|---|
| FR1 | 450 to 6000 MHz |
| FR2 | 24250 to 52600 MHz |
5G NR Base Stations must support specific channel bandwidths at different subcarrier spacings.

5G NR Base Station Classes
The following table outlines the different classes of 5G NR Base Stations (BS) or gNBs:
Table 3: 5G NR BS 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. |
