Huawei Debuts SingleRAN for WiMAX to LTE TDD Migration

Huawei announced commercial availability of an integrated WiMAX and LTE TDD SingleRAN solution that enables operators to seamlessly migrate from WiMAX to LTE TDD networks.

Huawei's solution consists of a WiMAX and LTE TDD dual mode remote radio unit (RRU) and dual mode base band unit (BBU). Both support 2.3GHz, 2.5GHz and 3.5GHz mainstream Time-Division Duplexing (TDD) frequency bands. The solution also features Huawei's SingleEPC packet core network solution, which supports GPRS, UMTS, LTE, and WiMAX users alike.

Huawei noted that its WiMAX RRU has been widely applied in several operators' current operating WiMAX networks. It is a 4T4R (four transmitters and four receivers) design that supports multi-input multi-output (MIMO) and Beamforming (BF), and it can be flexibly configured as a WiMAX module, a LTE TDD module, or a WiMAX and LTE TDD dual mode module simply by upgrading the software.

Huawei supported China Mobile to deploy the world's first pre-commercial network using its LTE TDD solution. This network successfully demonstrated a variety of mobile broadband services, including high definition (HD) transmission, HD video conference, HD video monitoring, HD video-on-demand (VOD) and HD live broadcasting to visitors in the 2010 Shanghai World Expo Park and some key pavilions.
