The superfast communications heralded by fifth-generation wireless technology will ultimately underpin everything from toasters to telephones, from electric cars to power grids. There is also a more powerful Galaxy S10 that ships with support for 5G technology and the smartphone has finally launched, but there's a catch here.
The carriers say 5G-enabled smartphones are capable of downloading data 20 times faster than existing 4G devices, which in theory would enable users to download movie files nearly instantly.
The implications of the new technology have pitted Washington against Beijing - whose firms dominate 5G technology - in an increasingly bitter standoff.
Claim and counterclaim: South Korea says it beat the U.S. by a few hours because three of its carriers-SK Telecom, KT, and LG Uplus-launched 5G services at 11 p.m. local time on Wednesday.
To date, SK Telecom has 27 million subscribers.
The company said it was working with its memory-chip making affiliate SK Hynix to build a highly digitised and connected factory powered by 5G technology. On Wednesday, Verizon of the United States said it launched the world's first 5G service.
South Korea claimed to be the first country to launch 5G, but that was disputed by USA carriers like AT&T, which say they rolled out 5G in limited areas as early as past year.
Meanwhile in the US, Verizon is offering the Moto Z3 with a 5G Moto Mod. SK Telecom will be launching commercial 5G services nationwide on Friday, April 5, in line with its competitors. "This is the latest in our string of 5G firsts". "I hope faster speeds will help me manage my time better". The service, however, was made available to mobile hotspot devices but is not yet on phones.
Japan is also expected to roll out a limited deployment in 2019 before full services start in time for next year's Tokyo Olympics.
Some will, no doubt, contend that the South Korean launches have already taken place, with widespread reports of 5G launches in the country on April 3.
5G is said to herald a new level of connectivity and speed.
"We're expecting the leap from 4G to 5G to be a much greater leap than ever before".
"South Korea is preparing to become the first country in the world, which will launch a super fast mobile Internet 5G", - stated in the message.
