Chinese equipment vendor ZTE and Hong Kong’s largest mobile operator by subscribers, CSL New World Mobility (CSL), have decided to 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, has 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 have successfully completed testing of QAM64 HSPA+ network capability in Hong Kong, capable of delivering up to 21 Mbps of download speed.
