SDR Distributed Base Station

ZTE distributed base station of GSM & UMTS SDR series products, is suitable for
multiple indoor and outdoor coverage scenarios. There are many types of
combination portfolios according to different RRUs connecting with BBU. It
develops a new solution for 2G/3G mixed networking and network evolution by only
one set of RAN equipments, so that the network construction cost is greatly
decreased.
Highlights
Series of RRU, Suitable for Various Coverage Scenarios
Series of RRUs with high output power and diversified power amplifier
transmitting and receiving design, are suitable for various coverage scenarios.
It enables operators to further balance the relationship between radio network
performance and investment.

Shelf Plug-in Dual-Mode BBU, Reliable Design & Easy Installation
ZTE BBU module has hot-standby design for main control board. Baseband resources
are shared in the form of resource pool, and common resources are shared between
GSM & UMTS, such as main control unit, transmission and CPRI interfaces. These
ideas promote the reliability and availability of dual-mode applications. BBU
can also be conveniently deployed on the wall, on the ground, etc. No dedicated
equipment space is required, easy for site selection, fast network deployment.

All IP Micro TCA architecture, Flexible Networking
Adopts Micro TCA architecture, ATM/IP dual protocol stacks, provides various
interfaces.

Dual Mode Configuration, Smooth Evolution
UMTS and GSM can be supported simultaneously. GSM/GPRS/ EDGE/Enhanced
EDGE/UMTS/HSPA/HSPA+ are fully satisfied as well as future evolution to LTE.

Multi-Carriers and Multi-Frequencies Support
RRU module supports UMTS carriers or GSM carriers in single mode, and GSM/UMTS
dual mode in multi-frequencies.

High Efficiency Power Amplifier, Low Power consumption
The PA efficiency achieves 50% with Doherty + DPD Technology that independently
developed by ZTE. 80W power amplifier (TOC) is supported, which can effectively
reduce the OPEX
