Network giant CSL launches 4G smartphone

CSL, the largest wireless network operator in Hong Kong, has teamed up with Taiwanese handset maker HTC to offer local mobile subscribers the first of a wave of new 4G smartphones set to reach the city this year.

The carrier, a unit of Australian telecommunications giant Telstra, is currently the sole network operator in Hong Kong that runs a high-speed 4G mobile infrastructure based on the industry standard called Long Term Evolution (LTE).
