Chapter 1 Product Overview
Compared with traditional eNodeB, eBBU+eRRU distributed eNodeB has lower power
consumption, which can greatly reduce the investment and cost on electric power, and
thus save the network operation cost.
5. Distributed networking, making good use of operators' network resources supporting
eBBU+eRRU distributed networking; supporting star networking mode between eBBU
and eRRU.
6. Adopting
a
more
perspective and generalized eNodeB platform.
eBBU adopts the platform designed for the future B3G and 4G. One hardware platform
can realize different standard modes, and several standard modes can coexist in one
eNodeB. In this way, operators' management can be simplified, and several eNodeBs
to be invested can be integrated into one eNodeB (multimode eNodeB). The operators
can select the evolution direction of the future network more flexibly.
1.2 Product Position in Network
ZXSDR R8882 L708 is a remote radio unit (eRRU) of distributed eNodeB. The signal is
transmitted or received through ZXSDR R8882 L708 to and from base band processing
unit for further processing through
CPRI
interface. By applying the distributed system, the
feeder loss will be reduced when the remote radio unit is positioned close to the antenna.
The coverage is enlarged with this solution.
