三星5G技术将在2020年实现商业化

韩国三星电子(Samsung Electronics)宣布率先开发出在毫米波(millimeter-wave) Ka频段运作、支持蜂窝通讯的的自适应数组收发器(adaptive array transceiver)技术；该公司表示，此新技术将会是未来“5G”移动通讯系统的核心，将可提供比目前 4G 网络高数百倍的传输速率。 三星预期， 5G 通讯时代将在2020年左右来临，将为使用者提供无所不在的Gbps等级通讯体验，届时每个基站都可达到数十Gbps的传输速率。而迄今产业界几乎还没开始推动所谓的5G技术标准；在世界许多地区，支持 4G 技术的网络甚至尚未布署。 根 据三星的说法，高速率 5G 蜂窝网络需要很大范围的频宽，就像是若想加强水流量就要更粗的水管那样；而一直以来毫米波因为具备不利传播的特性，都被认为在长距离传输资料方面有其限 制，但新的自适应数组收发器技术能在28GHz频段以1.056Gbps速率传输信息，传输距离可达2公里。 三星指出，该自适应数组收发器技术采用64个天线单元，能有效克服毫米波频段的无线电传播耗损──比传统频段高出几百MHz到数GHz──问题。该公司也表示将加速5G技术的研发，预定在2020年将毫米波频段的自适应数组收发器技术商业化。

{pagination} Samsung wants to launch 5G in 2020 Dylan McGrath South Korean giant claims first adaptive array transceiver technology operating in the millimeter-wave bands. Samsung Electronics Co. Ltd. said it has developed the world's first adaptive array transceiver technology operating in the millimeter-wave Ka bands for cellular communications. The South Korean giant said the new technology forms the core of a 5G mobile communications system and can provide data transmission up to several hundred times faster than 4G networks. According to Samsung, 5G, which Samsung hopes to have available around 2020, will be capable of providing a ubiquitous Gbps experience to subscribers anywhere and offers data transmission speeds of up to several tens of Gbps per base station. To date, there has been almost no standardization effort around 5G. In many parts of the world, equipment supporting 4G has not yet been deployed. According to Samsung, the implementation of a high-speed 5G cellular network requires a broad band of frequencies, much like an increased water flow requires a wider pipe. Tt has been long believed that the millimeter-wave bands had limitations in transmitting data over long distances due to its unfavorable propagation characteristics, Samsung said. But the new adaptive array transceiver technology transmits data in the millimeter-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to 2 kilometers, Samsung said. The firm maintains that the adaptive array transceiver technology, using 64 antenna elements, can be a viable solution for overcoming the radio propagation loss at millimeter-wave bands, much higher than the conventional frequency bands ranging from several hundred MHz to several GHz. Samsung said it plans to accelerate the research and development of 5G technologies, including adaptive array transceiver at the millimeter-wave bands, to commercialize those technologies by 2020. Samsung expects its latest innovation to spur research into 5G across the world, triggering the creation of international alliances and the timely commercialization of related mobile broadband services.
