1.1 Distributed eNodeB Solution

To supply customers with more competitive communication equipment and solution in the
market, ZTE develops and promotes ZTE SDR eBBU (baseband unit) and eRRU (remote
radio unit) distributed eNodeB solution timely, which jointly perform LTE eNodeB service.

ZTE distributed eNodeB solution is shown in Figure 1-1.

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

restricted

by the space of

equipment

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.

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.

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.

The product basic functions are listed below:

z Supports the configuration of 5 MHz, 10 MHz, and 15 MHz scalable

bandwidth.

z R8882 L708 supports 698 MHz~716 MHz(uplink)/728 MHz~746 MHz(downlink).
z Supports 2x2 MIMO on downlink.
z Supports QPSK,16-QAM,64-QAM on downlink, QPSK and 16–QAM on uplink.
z Supports transmission and receive power detection.
z Supports overload power protection for power amplifier.
z Supports power amplifier switching on/off function.
z ZXSDR R8882 L708 software failure will not affect the running of eBBU and other

ZXSDR R8882 L708s which are connected to it.

z Supports field strength scanning, temperature query, VSWR query, dry contact,

hardware/software resetting.
