2.2Functionality
ZXSDR R8862A S7100 is the remote radio unit of distributed base station. The
signal is transmitted /received through ZXSDR R8862A S7100 to/from base band
processing unit for further processing via standard CPRI interface.
By applying the distributed system, the feeder loss will be eliminated when the radio
unit is positioned close to the antenna. The coverage is enlarged with this solution.
The functions of ZXSDR R8862A S7100 include:

Support the LTE configuration of 1.4MHz/3MHz/5MHz/10MHz scalable
bandwidth defined in 3GPP

Band Supported: band 14
 Support 2T4R in one box which can optimize spectrum efficiency greatly and
improve network uplink performance

Support 64QAM modulation in both LTE downlink and uplink
 Support transmit power report function for every carrier

Support overload protection function for power amplifier
