Samsung unveils core tech of 5G mobile comms

Samsung Electronics announced last week that it has created the industry's first adaptive array transceiver technology operating in the millimetre-wave Ka bands geared for cellular communications. 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, Samsung claims.

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 standardisation 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 millimetre-wave bands had limitations in transmitting data over long distances due to its unfavourable propagation characteristics, Samsung said.

But the new adaptive array transceiver technology transmits data in the millimetre-wave band at a frequency of 28GHz at a speed of up to 1.056Gbit/s to a distance of up to 2km, 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 millimetre-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 millimetre-wave bands, to commercialise 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 commercialisation of related mobile broadband services.
