2.3 Product Features

Multi-Mode eRRU
ZXSDR R8882 L268 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 L268supports 2T4R (license needed), R8882 L188, R8882 L708, and R8882 L808
support 2T2R, which can optimize spectrum efficiency greatly and improve network uplink
performance. As a result, it brings better customer experience.
Higher Efficiency, Lower TCO
l ZXSDR R8882 L268's PA efficiency can reach up to 30% thanks to the most advanced
Doherty PA, DPD linear technology.
l
It supports dynamic adaptive PA power supply due to the output power, which reduces
power consumption.
