1.3 Product Features
Multi-Mode eRRU
ZXSDR R8882 L708 is fully software defined device. It supports multi-mode at the same
frequency band simultaneously. Therefore, it fully satisfies operators’ requirements of
hybrid network deployment and long term evolution with the lowest cost.
MIMO Supported, Better Performance
R8882 L708 supports 2T2R, which can optimize spectrum efficiency greatly and improve
network uplink performance. As a result, it brings better customer experience.
Higher Efficiency, Lower TCO
z
ZXSDR R8882 L708’s PA efficiency can reach up to 30% thanks to the most advanced
Doherty PA, DPD linear technology.
z
It supports dynamic adaptive PA power supply due to the output power, which reduces
power consumption.
1.4 Product Functions
ZXSDR R8882 L708 is the remote radio unit of distributed base station. The signal is
transmitted or received through ZXSDR R8882 L708 to/from base band processing unit
for further processing via standard
CPRI
interface.
