CSL deploys ZTE’s industry-leading carrier aggregation technology to achieve next-generation performance

10 September 2013, Shenzhen, China – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, today helped CSL Limited complete a demonstration of Hong Kong’s first 300Mbps-ready 4G network, paving the way for wider-scale commercial deployment of next-generation mobile services to consumers and business customers.

ZTE’s industry-leading carrier aggregation (CA) technology was deployed by CSL in the demonstration. ZTE’s capabilities in CA and LTE-Advanced (LTE-A) solutions help CSL to leverage its unrivalled radio spectrum assets to serve the needs of customers who demand the highest-performance mobile services.

As a key enabling technology in next-generation LTE-A networks, carrier aggregation technology combines two or more carrier frequencies in the same or different bands into one channel, increasing peak transmission speeds. ZTE’s CA solution helps unlock the potential of the spectrum assets of CSL, which is the only mobile operator in Hong Kong equipped with a pair of 20MHz spectrum in the 1800MHz and 2600MHz frequency bands for 4G services.

“ZTE is pleased to support CSL in bringing next-generation mobile services to customers in Hong Kong,” said Julian Wang, Managing Director for Hong Kong at ZTE. “The deployment of CA technology will enable CSL to strengthen its position as Hong Kong’s leading operator.”　

“LTE-A is the next step in the evolution of 4G LTE network service for CSL and our customers, one that allows us to optimise our spectrum advantage. We’re very happy to receive the support from ZTE in enabling us to demonstrate this latest technology first in the Hong Kong,” noted Phil Mottram, Chief Executive Officer of CSL Limited.

CA effectively addresses signal interference between neighboring cells that share the same band to improve the performance of LTE networks. By achieving load balancing between the master and the slave cells to increase network capacity, CA enables operators to provide consumers with higher networks speeds and a richer and more diversified mobile user experience.

Operators in the Asia Pacific region including SK Telecom have started deploying CA technology to offer trial and commercial networks. By combining a pair of 10MHz spectrum in the 800MHz and 1800MHz bands, SK Telecom’s network is capable of supporting peak transmission rates of 150Mbps.

CSL and ZTE have been long-term partners in developing next-generation mobile technologies, and bringing faster and better user experience to subscribers. In June, CSL and ZTE successfully completed a demonstration of High-definition voice over LTE network, capable of delivering high-quality voice services.
