Samsung and KDDI demonstrate 5G technology while on a moving train
Samsung and Japanese telecom company KDDI announced this morning that last month they were able to demonstrate the use of 5G technology on a moving train. During the testing, successful handovers of downlink and uplink transmissions were achieved while the train was moving at a speed of 100 km/hour (equivalent to 62.1 mph). While this was going on, Samsung and KDDI were able to post a peak data speed of 1.7Gbps.

The equipment employed consisted of Samsung's pre-commercial 5G end-to-end solution. This package includes a 5G router, a 5G radio, and virtualized RAN and core. And the testing revealed some of the typical features expected with a 5G connection such as low latency (which means that the network responds to commands with very little delay), high throughput and other capabilities that would benefit both riders and operators of high-speed trains.

Besides being able to handle the downlink and uplink transmissions, the 5G connection allowed 8K video to be downloaded using equipment placed on board the train. In addition, a 4K video shot using a camera mounted on the train was successfully uploaded.

Yoshiaki Uchida, Senior Managing Executive Officer at KDDI, expects the company to launch its 5G services by 2020. The test took place in Japan from October 17th through the 19th, in a city close to Tokyo.

That is all fine, but how will the towers actually handle this much data? That is where the bottle neck will occur when there are hundreds/thousands of users connected to the tower(s). What improvement in the infrastructure will there be to handle this much data increase? My best guess would be adding more fiber-optic lines coming to and from the towers themselves?

What do you mean? You're not going to be streaming 1.7Gbps data constantly, its more like when you're browsing the page takes 0.01 seconds to open instead of 1 second and then you spend a few minutes on that page.... It's not going to need a massive infrastructure change.

With the increase of data speeds, people are going to be able to stream higher quality content, correct? Presumably 4k video on a mobile device or tether to other devices. As mobile speeds increase, the way we utilize our devices will change too. No? The reintroduction of Unlimited plans has caused people to stream more HD Contect. So having faster speed would support the reasoning of higher quality video, no? Along with other attached devices to the network as well.

"people are going to be able to stream higher quality content" yes they are ABLE to do that, but most of them won't do that because it will drain data plan really fast. And I'm sure they won't give "unlimited" data plan for 5G, at least for now.

To take away Unlimited with faster service would not be a positive move for any carrier. After taking unlimited, and then bringing it back, to take it away again would really be a bad move. With the race to roll out 5G first between Verizon and AT&T, I think they will keep Unlimited with 5G.

Samsung always pushes the tech forward

They’re not the only ones. AT&T has been testing 5G for the last year is so. Not just cellular service but home WiFi to

More Samsung Innovation! In the past two decades Samsung has been accelerating technology more than any body else in the world.

Forgive me if I say the facts that will make you disappointed. In April 2008, NASA partnered with Geoff Brown and Machine-to-Machine Intelligence (M2Mi) Corp to develop 5G communication technology. On 22 February 2016, NTT DoCoMo and Ericsson succeed in World's first trial to achieve a cumulative 20Gbit/s with two simultaneously connected mobile devices in 5G outdoor trial. So there is nothing special that samsung do in terms of 5G they just join the party.

And here in india we still have slow 4G so much so that I don't believe it is 4G. Been to vietnam, philippines, thailand and used their sim cards and they're fast af (except for that one time in Can tho where it was having difficulties). Way so far than ours.

India always have 5-10 yrs lag in terms of technology.

Don't I know it. That's why people here go abroad. Not just to work but to migrate.

For me, the speed is not the main issue in India. The unreliable connectivity is the problem IMO. In Bangalore and Mumbai at least.

The real problem is their population that will surpass china's really soon :v Provider's infrastructure just can't catch up with the growth of smartphone users

Go to other countries and compare. You'll realize what you thought was an okay and acceptable speed, actually isn't. And those are south east asian countries i've been, not the more advanced east asian countries (taiwan, japan, south kor, china [hong kong] etc.) and yet still faster than ours. Anyways, we should just be grateful we're not in north kor :D
