Samsung announces breakthrough in 'ultra-high speed' 5G mobile phone network.


                                     

Samsung has developed 'ultra-high speed' fifth-generation technology that could allow users to download an entire film in a second, the electronics giant has said. The South Korean firm has successfully tested new equipment which it hopes will transmit data several hundred times faster than existing 4G networks.
It claims subscribers could use the technology to download high-quality digital films 'practically without limitation' and watch 3D movies or stream high-definition programmes in real-time.

HOW FAST WILL IT BE?
Samsung has been able to get speeds of 1 gigabit per second - far in excess of current 4G networks, which can manage 12 megabits per seconds.
According to Samsung, '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.'
Samsung believes its new transceiver is the world’s first device capable of providing 'ubiquitous' 5G broadband - and hopes to bring the service to customers by 2020.
It announced the development after conducting a test where data was transmitted at speeds of more than one gigabit per second over a distance of up to two kilometers. Customers using 4G services - currently provided in the UK by EE - access average speeds of between eight and 12 megabits per second (Mbps). '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 said in a blog post. The company believes the equipment could provide a solution to recent surges in wireless internet usage.
It added: 'Samsung’s 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.'

In the blog post, Samsung claims its technology uses high-frequency wavebands which were previously deemed unsuitable for mobile networks. Samsung has already trilled the technology over 2km distances, and found download speeds of 1 gigabit a second were possible, far higher than current 4G networks It said: '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, it has been long believed that the millimeter-wave bands had limitations in transmitting data over long distances due to its unfavorable 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 1.056 Gbps to a distance of up to two kilometers.'
