SoC selected to expand Datang's 4G deployment in China

With the rapid development of Chinese mobile technology and growing requirements on voice and video media services, subscribers now require better coverage and higher-capacity mobile networks. The collaboration between DTM and Broadcom will play an important role in future TD-LTE expanding network deployments by providing a smooth migration path from 3G TDSCDMA to 4G TD-LTE.

"As Chinese consumers demand for continuous and high quality coverage that supports voice, video and data continues to rise at a dramatic rate, mobile operators are seeking a low-cost, easy to deploy solution," said Greg Fischer, Broadcom Vice President and General Manager for Broadband Carrier Access. "By leveraging our small cell SoCs, leading cellular vendors such as Datang Mobile can quickly and cost-effectively develop small cell solutions that address these increasing capacity demands."

"Datang Mobile is an innovator in the Chinese communications industry, and has demonstrated excellent R&D capabilities and proven expertise in building large cellular networks," said Wang Xinmin, Datang Mobile vice Chief Engineer and General Manager for Mobile Communications. "By integrating Broadcom's advanced small cell SoC technology, we can build best-in-class carrier-grade enterprise and residential small cell solutions to maximize spectrum efficiency and offer multiple radio access technologies with the highest capacity to our customers."
