Samsung claims 5G mobile data transmission breakthrough
Samsung suggests its tech could be used in commercial
products as soon as 2020
BBC News
May 13, 2013
Samsung says it has developed technology that could sit
"at the core of 5G" - the successor to the 4G mobile-
communications standard.
The company says its equipment is capable of transmitting
data at more than 1Gbps across a distance of up to 2km
(1.2 miles).
It suggests the tech would eventually allow users to
stream ultra-high-definition video while on the move.
However, one expert says the news needs to be put in
context.
Prof Rahim Tafazolli - who heads up the University of
Surrey's 5G research efforts - suggests that even if the
latest development was used, it would only be "a small
part of the larger jigsaw" of technologies needed to
deliver 5G.
His words carry weight since his own �35m project to
develop a 5G standard is part-funded by Samsung.
3D video
Samsung says it has developed the world's first "adaptive
array transceiver" technology, an innovation that allows
part of the super-high-frequency Ka band of the radio
spectrum - at 28GHz - to be used for cellular data
transmission.
The firm indicates its equipment, which features 64
antenna elements, overcomes a problem involved with using
this frequency, which can cause the signal to weaken in
rainy conditions.
"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," said Chang-
Yeong Kim. head of the firm's Digital Media &
Communication Centre in Seoul.
A press release added that the South Korean firm hoped
devices based on the technology could be brought to
market by 2020, offering mobile data transfers "up to
several hundred times faster" than today's 4G tech.
"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," it said.
Capacity crunch
Prof Tafazolli stressed it would still be some years
before the 5G standard was finalised.
His own team's efforts were focused on transmitting data
over an even higher frequency band in the radio spectrum,
he added.
He also said it was not inevitable that whatever
technology was agreed on would offer much faster data
speeds, suggesting that finding a way for the next-
generation system to cope with the expected growth in
demand for mobile data use might take priority.
"Some of the companies are still putting too much
emphasis on speed when discussing going from one
generation to another generation," he said.
"In my opinion 4G achieves a decent speed and what we
need to do is crack the capacity crunch we are facing."
Prof Tafazolli's work is funded by Samsung, Huawei,
Fujitsu Laboratories and the UK government, among others.
Alternative work is being carried out in Japan, China and
elsewhere.
Developing the technologies involved in 5G could prove
lucrative.
As an industry standard, its inventors would have to
license the innovations involved to rivals, but they
would be able to charge a small fee for each device that
used them.
Discussions about which part of the radio spectrum to use
will take place at the UN's World Radiocommunication
Conference in 2015.
