Huawei Technologies has demonstrated the world's first unified 4G system for operators at the Mobile World Congress in Barcelona.
The frequency-division duplex and time-division duplex (FDD/TDD) long-term evolution (LTE) system enables more efficient use of spectrum resources, and helps operators deliver the highest-quality mobile broadband networks at a significantly reduced cost, said Huawei.
Wan Biao, president of the Huawei Wireless product line, said, "Huawei hopes to pave the way for network convergence and evolution by developing innovative systems that enable operators to simplify and unify their networks in preparation for future mobile service demand".
In January 2009, Huawei was awarded the world's first LTE (4G) commercial contract by TeliaSonera, the largest telecommunication operator in Scandinavia and the Baltic countries.
Motorola is conducting UK 4G networking tests in Swindon.
