Figure 1-1 ZTE Distributed eNodeB Solution
ZTE's LTE eBBU+eRRU distributed eNodeB solution has the following predominance:
1. Saving labor cost and engineering cost for networking.
eBBU+eRRU distributed eNodeB equipment is small in size, light in weight, and easy
for transportation and engineering construction.
2. Fast networking, also saving the fees of renting equipment room.
eBBU+eRRU distributed eNodeB is applicable to various sites, such as mounted on
steel tower, on building top, or on wall, etc. It's more flexible in selecting installation
site, and not

room. It can help operators to deploy
network rapidly. It can also save the fees of renting equipment room, and the network
operation cost.
3. Convenient in upgrade and capacity expansion; saving the initial stage cost of the
network.
eRRU can be mounted as close to antenna as possible, to save the cost of feed cable
and decrease the loss of feed cable. It also can enhance the output power of eRRU
and increase the coverage.
4. Low power consumption, power-saving.

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.

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.
