Samsung says in a statement that 5G is the next generation of the existing 4G long-term evolution (LTE) network technology, and will provide data transmission speeds up to several hundred times faster than current 4G networks.
Samsung’s new adaptive array transceiver technology transmits data in the millimetre-wave band, at a frequency of 28GHz, at a speed of up to 1.056Gbps, to a distance of up to 2km.
“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 says.
The Korean manufacturer plans to accelerate the research and development of 5G mobile communications technologies, including adaptive array transceivers at the millimetre-wave bands, to commercialise the technologies by 2020.
“The millimetre wave band is the most effective solution to recent surges in wireless Internet usage. Samsung’s recent success in developing the adaptive array transceiver technology has brought us one step closer to the commercialisation of 5G mobile communications in the millimetre wave bands,” says executive vice-president of Samsung Electronics, Chang Yeong Kim.
The successful testing of 5G comes less than a year after LTE. The technology operates at more than double the speed of any mobile connection and provides significant multiples faster than the 2G and 3G connections common across the country.
While 5G is still a long way from being made available to the general public, Africa Analysis telecoms analyst Dobek Pater believes the adoption of 5G will depend on the need thereof. “In the past, operators have been prepared to take a big risk on ROI in building out 3G networks and now LTE networks. They may not have an appetite for that with 5G, depending when it becomes available as a standardised and approved technology.”
He adds that local mobile operators have been some of the first in the world to deploy new access technologies like 3G and LTE, and local operators may decide to deploy the new technology. “But it would probably be more for marketing than true commercial reasons. However, I think, with the 5G technology, operators will think long and hard about its business case before deployment, unlike with earlier technologies.”
