HONG KONG, 3 JULY 2009 – Hong Kong-based mobile network operator CSL has replaced its network with what its partner ZTE calls “the world’s fastest SDR-based evolved high-speed packet access (HSPA+) commercial network” in an effort to achieve major network power reduction.
CSL, a subsidiary of Australia’s telecommunications company Telstra, will offer a download rate of up to 21 megabits per second using the 3G network for their third-generation (3G) subscribers as a result.
39 per cent power reduction
This project also brings environmental benefits to CSL. The BBU+RRU modular hardware deployed by China-based network solutions provider ZTE offers power reduction by about 39 per cent per year, and natural heat elimination to effectively help reduce 7,000 tonnes of carbon dioxide emissions. This energy savings is equivalent to the emissions from 1,000 automobiles in three years over 60,000 km.
Christian Daigneault, chief technology officer of CSL, said: “CSL is pleased with ZTE’s project delivery capabilities and expertise in handling CSL’s complex network requirements, ensuring a smooth and transparent migration that enables the highest data speed in the mobile industry.”
CSL’s Hong Kong SDR-based HSPA+ network project has set many industry records: the world’s first all-IP HSPA+ commercial network; the world’s first large-scale SDR-based application; and the first large-scale migration project.
