Samsung Electronics said Monday it had made a key breakthrough in developing mobile technologies for so-called fifth-generation networks that would provide data transmission up to several hundred times faster than the current fourth-generation, or 4G, technology.

The breakthrough helped Samsung overcome limitations in transmitting large volumes of data over long distances using a broad band of frequencies, the company said in a news release. Samsung, the world’s biggest maker of mobile phones, said it would accelerate the research and development to commercialize those technologies by 2020.
