A month after Chinese top technology vendors stole the limelight at the Consumer Electronics Show in Las Vegas, they are taking center stage once again at the Mobile World Congress－the world's biggest exhibition for the mobile industry, being held in Barcelona this week.

Technologies to be used in fifth-generation telecom networks are attracting the biggest interest at the event, which is running from Monday to Thursday, with Chinese companies showcasing products alongside global giants including Samsung Electronics Co and Nokia Corp.

ZTE Corp, the Guangdong-based telecom equipment maker, is demonstrating its high-frequency prototype and other key 5G technologies.

The company is hoping to take a lead in technology development, so when 5G starts commercial use in five years from now, it will enjoy a technology edge, said industry observers.

China Mobile Communications Co, the country's largest carrier by subscriber, is also aiming at the 5G market, despite only kicking off its 4G services a little more than two years ago.
