5G NR UE Power Classes | Class 1, Class 2, Class 3, Class 4

This page describes 5G NR UE Power Classes or types viz. class 1, class 2, class 3 and class 4. The 5G NR UE power classes include minimum peak EIRP and maximum output power limits as per 3GPP standard.

Introduction:
The 5G NR (New Radio) is the latest wireless cellular standard which follows 4G standard (LTE, LTE-a) It follows 3GPP specifications release-15 and beyond. Mobile Subscriber or station in 5G NR is known as UE (User Equipment).

5G NR UE can be used in frequency ranges FR1 (450 to 6000 MHz) and FR2 (24250 to 52600 MHz). Following table-1 mentions downlink and uplink frequency ranges for n257, n258, n260 and n261 FR2 bands.


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

Following tables mentions 5G NR UE power class 1 minimum peak EIRP and maximum output power limit specifications. Here EIRP stands for Effective Isotropic Radiated Power and TRP stands for Total Radiated Power.
