5G NR UE Power Classes Explained

5g nr user equipment power class wireless technology

This page describes the 5G NR UE Power Classes or types, specifically class 1, class 2, class 3, and class 4. It outlines the minimum peak EIRP and maximum output power limits for 5G NR UEs, according to the 3GPP standard.

Introduction

5G NR (New Radio) represents the latest generation of wireless cellular technology, building upon the foundation laid by 4G standards like LTE and LTE-Advanced.

It adheres to the 3GPP specifications, starting from Release-15 onwards. In the context of 5G NR, a mobile subscriber or station is referred to as a UE (User Equipment). 5G NR UEs are designed to operate across two primary frequency ranges: FR1 (450 to 6000 MHz) and FR2 (24250 to 52600 MHz).

Table 1 shows the downlink and uplink frequency ranges for n257, n258, n260, and n261 FR2 bands.

Table 1: 5G NR Band Frequency Ranges

5G NR Band	Uplink range (UE transmit/BS receive)	Downlink range (BS transmit/UE receive)	Duplex mode
n257	26500 to 29500 MHz	26500 to 29500 MHz	TDD
n258	24250 to 27500 MHz	24250 to 27500 MHz	TDD
n260	37000 to 40000 MHz	37000 to 40000 MHz	TDD
n261	27500 to 28350 MHz	27500 to 28350 MHz	TDD

The following tables provide the 5G NR UE power class specifications, including the minimum peak EIRP (Effective Isotropic Radiated Power) and maximum output power limits. TRP stands for Total Radiated Power.
