ZTE Helps CSL with Cutover to HSPA+ Network

(Top News, 2 Jul 2009)

ZTE Corp., a global provider of telecommunications equipment and network solutions, together with Hong Kong’s leading mobile operator, CSL Limited (“CSL”), announced a significant milestone with the successful cutover of CSL’s Hong Kong network to the world’s fastest SDR-based HSPA+ commercial network; and a major achievement in network power reduction. CSL 3G subscribers are now experiencing high-speed wireless services through the ZTE-deployed HSPA+ 3G network with a download rate of up to 21Mbps.

This project brings significant environmental benefits to CSL and the Hong Kong community as a whole. The BBU+RRU modular hardware innovated and deployed by ZTE for this project offers highly efficient power consumption and natural heat elimination to effectively help reduce CO2 emissions. With the deployment of ZTE’s environmentally friendly equipment, the overall network power consumption of CSL’s network will be reduced by about 39 percent per year. This energy savings is equivalent to 7187 tons of CO2 emission, or emissions from 1,000 automobiles in 3 years over 60,000 km.

Following the high-speed SDR-based HSPA+ commercial network launch by CSL on March 30, 2009, ZTE has assisted CSL in a series of network migrations to transform its previous network to HSPA+ for its pre-paid, post-paid and corporate customers. CSL previously operated two GSM/WCDMA networks which required significant and costly network upgrades. The network migration needed to be done with no interruption of service and no impact to customer experience. After six months of planning and thousands of tests, ZTE has successfully completed the cutover.

“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,” said Mr. Christian Daigneault, Chief Technology Officer of CSL.

“We are pleased to help CSL build a high-speed, high efficiency network for the Hong Kong market,” said Mr. Xu Huijun, Vice President, ZTE Corporation. “Backed up by our high-quality products and effective team members, ZTE’s advanced SDR technology helps CSL optimise its operation efficiency while improving the network competency to meet its increasing customer needs.” CSL’s Hong Kong SDR-based HSPA+ network project has set many first 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.
