About :- *5G .
Recently, a report from Deloitte estimated that China and other first-
adopter countries "could sustain more than a decade of competitive
advantage" and reap big economic gains from early investments in
the next generation of mobile technology. The Deloitte report
describes 5G as a prize to be won, while others have chosen to
portray it as a staging ground for geopolitical rivalries.
In fact, 5G is a neutral technology that will support many
dimensions of tomorrow's digital economy. The 5G revolution will
arrive in two stages. The first will provide super-fast internet
connections for homes and businesses, enabling ultra-high definition
video and virtual and augmented reality; it will also help bring
broadband to the roughly 1 billion homes lacking broadband access
in emerging markets. A second wave, due to be completed in
December 2019, will support more futuristic applications, such as
robotic surgery and autonomous cars.
Each generation of mobile technology outperforms the one before it,
and 5G will be 100 times faster than 4G, and 50 times more
responsive. Beyond a certain speed, however,data transmission
becomes unreliable: Signal gets impeded by noise, a form of digital
corruption that introduces errors into the data.

2. Scientists have known this since 1948, when an American
mathematician named Claude Shannon determined that there is a
limit to the speed at which data can be transmitted without error.
That's why every breakthrough in the telecommunications
infrastructure "copper,optical fibre, wireless transmission" has been
accompanied by parallel improvements in digital coding technology,
ensuring that data didn't get scrambled on their high-speed journey.
As telecom networks got faster, managing this trade-off between
reliability and speed grew more challenging. Now that 5G's blazing

3. bandwidth is just around the corner, data will have to be encoded in
the right way.
Not long ago at its Shenzhen headquarters, Huawei welcomed a
visiting scholar from Turkey named Erdal Arikan who 10 years ago
wrote a paper containing the seeds of a breakthrough that will
enable fifth-generation mobile technology (5G) to transmit huge
quantities of data at extremely high speeds, reliably and without
error. An MIT-trained expert in electrical engineering at Bilkrent
University in Ankara, Turkey, his paper looked at the possibilities of
something called polar codes, a mathematical technique which, he
believed, might push data transmission speeds to within a hair's
breadth of the Shannon limit. Huawei had begun its own research on
5G technology around the same that the professor had published his
paper. Although polar coding was still in its early stages, the
company decided to make further investments in this embryonic
technology. Last December, the coding technique pioneered by
Arikan was adopted as a basic element of 5G standards.
5G will usher in a digital economy whose momentumbuilds as the
technologies supporting it become more widely adopted. These
technologies will be largely invisible, and most people won?t know
anything about them. But like Arikan's polar codes, they will be
quietly running in the background,taking what had been science
fiction and turning it into reality.
