After South Korea became the first country in the world to commercialise the 5G wireless network for mobile subscribers, there's been much anticipation on how 5G can change everyday life.
To dive deeper into the issue, we have our IT correspondent Oh Soo-young in the studio with us.
So Soo-young, we keep hearing that 5G will be 20 times faster than LTE. How will this massive improvement in speed translate into our daily lives?
Well, if you want to download a video and it took you twenty seconds with LTE, it will now only take a second. Also, the lag time that you experience with 4G will drop by 90%, down to just 1 millisecond. That's 100 times faster than a blink of an eye.
To show how this can fit into our daily lives, I visited a couple of places in Seoul.
A 5G pop-up center in Gangnam has attracted more than 50 thousand visitors, in the first two weeks since it opened earlier this month.
Using VR goggles that run seamlessly on 5G, you can star in your favourite K-Pop performances and even find a celebrity companion to go on a virtual date with.
"It's so three-dimensional. I can even see the wrinkles "
You can play online games and watch sports in real time from various angles and through the eyes of multiple players.
"It was a lot more immersive and visceral and it was easy to play as well. Pretty quick. There was no lag or anything like that. It was just like playing on a game console, you know."
Taking a break at a hotel is also expected to become an upgraded experience.
At an AI hotel in Eastern Seoul, powered by KT Corporation, most room service functions , like amenities and controlling the air conditioning, are already available on demand through AI, and of course the most important thing
"What is the wifi password?"
The hotel plans to enhance these services even more with the introduction of 5G robots this year.
Telecom firms have also introduced 5G offices, restaurants and even concerts that run on the super-fast network.
