Foreword

The BSC6900 is an important network element (NE) of

Huawei Single RAN solution. It adopts the industry-leading

multiple radio access technologies, IP transmission mode,

and modular design. It features high capacity, high

integration, excellent performance, and low power

consumption.

The BSC6900 can be flexibly configured as a BSC6900

GSM only, BSC6900 UMTS only, or BSC6900 GU as

required in different networks

Flexible Topologies and Smooth Evolution

The BSC6900 can be flexibly configured as a BSC6900 GSM,

BSC6900 UMTS, or BSC6900 GU; therefore, it is applicable to

various networking scenarios.

The BSC6900 can be configured as one of the three variants,

therefore facilitating the smooth evolution between GSM,

GSM&UMTS, and UMTS.
