CSL New World and ZTE aim to claim first SDR-based HSPA+ network

17 Feb 2009

Chinese equipment vendor ZTE and Hong Kong’s largest mobile operator by subscribers, CSL New World Mobility (CSL), have announced that they will work together to build the world’s first large-scale all-IP network based on Software Defined Radio (SDR) and HSPA+ mobile broadband technology. CSL, a subsidiary of Australia’s Telstra, said it selected ZTE via a competitive tender to upgrade its existing infrastructure with a fully integrated 2G/3G all-IP SDR-based network. Furthermore, ZTE and CSL successfully completed testing of QAM64 HSPA+ network capability in Hong Kong on 15 February, capable of delivering up to 21Mbps download speed. According to a press release, SDR-based solutions enable operators to upgrade to next generation networks, including HSPA+, MIMO and LTE. CSL CEO Tarek Robbiati said that Hong Kong’s urban geography presented a tough challenge to the project’s aims: ‘Many skyscrapers and the dense population create a complicated wireless environment. So the reconstruction of a converged all-IP 2G/3G network is a challenging task. We congratulate ZTE on the system’s outstanding performance in QAM64 testing and we believe our work with them will help CSL New World Mobility to…deliver its 2.5 million subscribers superior service,’ he claimed. ZTE CEO Yin Yimin said, ‘ZTE set up a special project team comprised of more than 300 engineers and technical experts to work with CSL. We are very proud that together we are enabling the world’s first SDR-based HSPA+ network.’
