ZXSDR R8854 Product Description 1 Overview 1.1 Introduction This document provides a high level description of ZTE ZXSDR R8854 (hereinafter R8854), which is a new compact 4T4R RRU (Remote Radio Unit) used in ZTE wireless total solution. R8854 provides 4-way transmission and 4-way reception to implement LTE 4T4R. The RRU is based on ZTE common RRU platform, and works in GSM, UMTS, LTE, NB-IoT single mode or multi-mode through software configuration.
ZXSDR R8854 Product Description Note: To be compliant with Radio Equipment Directive (RED) of European Union, this device is restricted to use and put into service due to the need for a spectrum license and/or the conditions attached to authorization for the use of frequencies within all European Union countries (BE/BG/CZ/DK/DE/EE/IE/EL/ES/FR/HR/IT/CY/LV/LT/LU/ HU/MT/NL/AT/PL/PT/RO/SI/SK/FI/SE/UK). 1.
ZXSDR R8854 Product Description Figure 1-2 Application Scenarios Antenna Antenna ANTENNA R8894 R8892N R8854 B8200 B8200 B8200 1.4 Functionality R8854 is a remote radio unit of distributed base station. The signal is transmitted through R8854 to base band processing unit for further processing via standard CPRI interface. The antenna should be installed and operated with minimum distance 4.55m between the radiator and human body.
