LG runs a successful 6G THz outdoor transmission test

By Thomas Hindmarch August 19, 2021

LG Electronics has announced a successful short-range test for 6G terahertz (THz) data, bringing the eventual 6G future that much closer.

LG worked in conjunction with the Fraunhofer-Gesellschaft research laboratory in Germany to conduct the test, which saw the data transmitted wirelessly between the Fraunhofer Heinrich Hertz Institute and the Berlin Institute of Technology. It successfully traveled over 100 meters in an outdoor setting, which breaks records that were previously set under controlled laboratory conditions.

LG did not specify what the data was, how much was transmitted, or how long it took, but previous 6G transmission tests have achieved 48GB-per-second speeds. (Pulling down a full digital installation of Microsoft Flight Simulator in under three seconds? Sure, I’ll take that.)

Pulling off a short-range data transmission may not sound that impressive at the moment, with 5G available just about everywhere, but LG’s transmission test is a new milestone for 6G, which is still in its relative infancy. Previous tests have shown that in theory, 6G could be as much as a hundred times faster than 5G, but it’s currently limited by its short-range and high power requirements.

LG and its German collaborators were able to boost the 6G signal’s transmission distance by codeveloping a new kind of power amplifier that uses adaptive beamforming technology — which uses signals from an array of transmitters in order to increase their strength — to boost 6G output. LG was testing a lot of new tech here, all at once, and it seems to have worked out.

“The success of this test demonstrates that we are ever closer to the successful application of terahertz radio communication spectrum in the upcoming 6G era,” said I.P. Park, the president of LG, in a prepared release.

Again, this is a step along the road to a full-fledged 6G rollout, which is generally planned for the future but still doesn’t have a firm release date. LG claims in its press release to have targeted 2025 for global 6G standardization, with commercialization to come over the course of the following four years, but that seems to be one of the more optimistic forecasts to date.

In other words, it’s probably not worth waiting for 6G instead of upgrading to a 5G-capable phone.

The 15 most important smartphones that changed the world forever

Huawei P30 Pro and P30

If there’s any piece of technology that has made a significant impact on the lives of everyone, it’s the cellular phone — specifically, the smartphone. It’s literally a tiny computer that fits into your pocket, and brings a plethora of information, entertainment, and lets you capture visual memories or be productive wherever you go. Pretty much everyone has a smartphone these days, for better or for worse.

But have you ever thought about which smartphones have been the most important and influential ones that shaped the rest of the industry? Let’s take a look at what we consider to be the most important smartphones of all time.

What is 5G UW? The real meaning behind the icon on your phone

You've probably noticed that there's been much more hype around 5G than for any of the wireless technologies that came before. Some of that is just marketing, of course; we are living in an increasingly connected era, and there are far more people toting smartphones now than there were in 2012 when 4G/LTE was just beginning to go mainstream. However, it's also not an exaggeration to say that with considerably faster speeds and the ability to handle many more devices, 5G is a much bigger step into the next stage of global connectivity. You've also probably noticed it yourself with a "5G UW" icon at the top of your phone.

As with most new technologies, 5G comes with some new challenges for both carriers and consumers. One of the most significant of these has been working out the best way to deploy 5G services across the much wider range of frequencies that it's capable of operating on. This wasn't nearly as significant a problem in the days of 3G and 4G/LTE services, which all operated in a much narrower range of radio spectrum.

What is 5G? Speeds, coverage, comparisons, and more

It's been years in the making, but 5G — the next big chapter in wireless technology — is finally approaching the mainstream. While we haven't yet reached the point where it's available everywhere, nearly all of the best smartphones are 5G-capable these days, and you're far more likely to see a 5G icon lit up on your phone than not.

There's more to 5G than just a fancy new number, though. The technology has been considerably more complicated for carriers to roll out since it covers a much wider range of frequencies than older 4G/LTE technology, with different trade-offs for each. It's also a much farther-reaching wireless technology, promising the kind of global connectivity that was once merely a dream found in futuristic sci-fi novels.
