SK Telecom and POSTECH develop 5G antenna tech

Published

on

SK Telecom and Pohang University of Science and Technology (POSTECH) has developed a 5G antenna control technology and filed for a patent, they announced on Tuesday.

The pair’s technology maintains call quality in ultra-high 28GHz spectrum 5G by controlling the electrical characteristic of the antenna.

Ultra-high frequency reception sensitivity is affected by how users hold their smartphones or the angle of their head, but this technology was developed to offset that, they said.

Increasing reception sensitivity also decreases power consumption of smartphones.

Ultra-high spectrum such as 28GHz requires components to be placed in a smaller area compared to LTE, with SK Telecom and POSTECH saying they also took this into account when finishing testing for commercial launch.

SK Telecom, with compatriots KT and LG Uplus, is also preparing for the rollout of 5G in March in South Korea. The company excluded Huawei from its equipment vendor list in September last year. 

SK Telecom is a close ally of Samsung Electronics, and is extensively collaborating with them in 5G equipment research.

This Tesla Supercar Is The Future Of Electric Cars We Want Elon Musk To Build

Published

on

British concept artist Khyzyl Saleem took to Instagram and Facebook to reveal the Tesla Precept Concept, a Tesla supercar/hypercar in the eyes of an under-30 designer. More than just a flight of fancy, the design was Saleem’s final submission for his Meguiar’s art piece dubbed “Electrifying 2020,” and it looks brilliant.

Saleem took influence from modern hypercars like the Czinger 21C, Rimac Nevera, Lotus Evija, and the Porsche Mission R concept to finalize his creation. But in our eyes, the Tesla Precept more closely resembles the offspring of a first-gen Tesla Roadster and a McLaren supercar, particularly a 765LT. The front clip is a bit off with its intricate hood design, and the Tesla “mustache” grille looks like an afterthought, but the rear is not too bad. We fancy the recessed taillight and wing spoiler design, and that swooping design on the diffuser is fascinating.

The artist claims the design is a “super early and kinda rough version” that, given more time, would have been something more unique. Tesla’s incoming Roadster is not a bad-looking car, but the Precept Concept proves what could have been if Tesla designers had taken a swill of scotch before buttoning down for work.

Indiana Is The First State To Sue TikTok Over Child Safety Worries

Published

on

To tech-savvy and/or historically informed readers, the widespread concern about TikTok in the U.S. might smack of earlier moral panics. As mental health nonprofit Take This reports, it’s a matter of record that social media, video and tabletop games, clothing choices, music genres, and virtually anything else enjoyed by the young have been excoriated by American elders on one moral basis or another.

At the same time, serious questions have been raised about the safety of TikTok as a platform. We’ve reported in the past about the successes and failures of TikTok’s content moderation, from its largely hands-off, algorithmic approach to managing content to the borderline unethical treatment experienced by the human moderators the platform does possess. Content capable of generating severe psychological trauma in adult professional content managers certainly shouldn’t be emerging in children’s feeds.

Moderation and data security are also inescapably entwined. Hands-off moderation doesn’t just threaten the possibility of traumatic content in users’ feeds; it allows for sharing media at least some users are likely to see as unethical if not illegal. Add that to the documented pressures that Chinese law puts on social media platforms and it starts to seem like the Indiana lawsuit, right or wrong, at least has some kind of grounding.

Still, TikTok has answered critics and survived plenty of tough talk from the previous presidential administration. Whether it can continue to do so will depend both on the commitment of the platform’s user base and its ability to adapt to the requirements of American law.

How Fast Is The Electric Harley-Davidson Motorcycle Really?

Published

on

According to Livewire, the ONE has some impressive speed and acceleration numbers, going from 0-60 mph in just three seconds and topping out at 110 mph. Sure, 110 mph doesn’t seem awfully fast, but Harley-Davidson motorcycles were never known for being fast. According to testing by CycleWorld, the Livewire ONE lives up to its reputation, accelerating from 0-60 mph in 3.1 seconds — a fraction of a second slower than the marketed number.

Interestingly, in terms of acceleration, the Livewire ONE is second only to the FXDR 114, which has a 0-60 mph time of only 2.5 seconds, according to Harley Davidson of Kingwood. Being quick off the line is par for the course for an electric motorcycle, though — there are no gears to cycle through, and electric motor torque is usually much higher at low RPM. The highest top speed for a production Harley-Davidson bike also goes to the FXDR 114, which tops out at a respectable 160 mph, according to Peterson’s Harley-Davidson. As far as the Livewire ONE’s 110 mph top speed, that’s par for the course for Harley-Davidson, with most everything except for the FXDR 114.
