Samsung Electronics says it has developed the world’s first adaptive array transceiver technology operating in the millimetre-wave Ka bands for cellular communications.
The new technology sits at the core of 5G mobile communications system and will provide data transmission up to several hundred times faster than current 4G networks.
Samsung says 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,” said Chang Yeong Kim. Samsung’s head of digital media and communications.
“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,” he said “While it was a recognised option, it has been long believed that the millimetre-wave bands had limitations in transmitting data over long distances due to its unfavourable propagation characteristics.
“But Samsung’s new adaptive array transceiver technology has proved itself as a successful solution. It transmits data in the millimetre-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps 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 millimetre-wave bands, much higher than the conventional frequency bands ranging from several hundred MHz to several GHz.”
Kis said Samsung plans to accelerate the research and development of 5G mobile communications technologies, including adaptive array transceiver at the millimetre-wave bands, to commercialise those technologies by 2020. Samsung said its innovations will invigorate research into 5G cellular communications across the world.
The competition for technology leadership in next-generation mobile communications development is getting increasingly fierce. China established a government-led IMT-2020 5G Promotion Group in February 2012, while the European Commission also plans to invest €50 million in 2013 to bring 5G services to the market by 2020.
“Once commercialised, 5G mobile communications technology will be capable of ultra-high-speed data transmission up to several hundred times faster than even the 4G LTE-Advanced technology due for launch later this year,” said Kim.
“Our new technology will allow users to transmit massive data files including high quality digital movies practically without limitation. As a result, subscribers will be able to enjoy a wide range of services such as 3D movies and games, real-time streaming of ultra high-definition (UHD) content, and remote medical services.”
