5G: 1Gbps and beyond
Samsung Electronics announced that it has successfully developed the world’s first adaptive array transceiver technology operating in the millimeter-wave Ka bands for cellular communications.
The new technology sits at the core of 5G mobile communications systems and will provide data transmission up to several hundred times faster than current 4G networks.
According to Samsung, 5G mobile communications technology is the next generation of the existing 4G Long Term Evolution (LTE) network technology.
“5G 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,” Samsung said in a press statement.
Millimeter-Wave Transceiver Technologies for 5G Cellular Networks
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.
While it was a recognized option, the prevalent view was that the millimeter-wave bands had limitations in transmitting data over long distances due to its unfavourable propagation characteristics.
However, Samsung’s new adaptive array transceiver technology has proved itself as a successful solution.
It transmits data in the millimeter-wave band at a frequency of 28 GHz at a speed of up to 1.056Gbps to a distance of up to 2 kilometres.
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 plans to accelerate the research and development of 5G mobile communications technologies, including adaptive array transceiver at the millimeter-wave bands, to commercialize those technologies by 2020.
