Samsung Electronics Co., the world’s top maker of smartphones, launched Thursday the world’s first smartphone that runs on a broadband long-term evolution advanced network, starting another round of competition among local mobile carriers over speed.

The device, the Galaxy S5 Broadband LTE-A, will first be launched through SK Telecom Co., South Korea’s top mobile carrier, and gradually add other players, namely KT Corp. and LG Uplus Corp.

The broadband LTE-A, three times faster than the current LTE network, will allow users to download a 10 megabyte video clip in 0.4 seconds.

Like the original Galaxy S5, the device is equipped with a 5.1-inch display, a 16-megapixel camera and a 2,800-mAh battery. It also keeps key features, such as a fingerprint scanner and heartbeat sensors.

The updated model has a Wide Quad HD Super AMOLED display, compared with the original device’s Full HD Super AMOLED. (Yonhap)
