NTT and NEC use 5G to stream 8K footage of a steam locomotive to its passengers

Japanese telco NTT DoCoMo and compatriot conglomerate NEC have teamed up to stream 8K footage of a steam locomotive back into the train.

“8K ultra-high-definition live video featuring a steam locomotive train was transmitted from a 5G base station installed along a railroad to a 5G mobile station located inside a running SL train and put on an 8K display,” NEC said on Friday about the test conducted in November.

The test also streamed 4K content to passenger handsets, however with the lack of 5G handsets available, the content hit the passenger mobiles via Wi-Fi from a 5G station on the train.

The NEC base stations used supported 4.5GHz and 28GHz bands, with the test itself forming part of a Japanese government project to examine the outdoor use of 5G systems that have average data speeds of 4Gbps to 8 Gbps.

Last week at CES 2019, Samsung displayed a 5G smartphone prototype in a glass case.

The company also said it will be releasing a 5G handset in 2019, with Australian telco Telstra saying it has multiple agreements to offer 5G smartphones in the first half of 2019.

Telstra rival Optus announced on Monday that it had conducted a 5G data call across 60MHz of its 3.5GHz spectrum when setting up its 5G fixed wireless network.

The call was made between an Optus site and indoor Nokia customer premises equipment. The Singtel-owned telco said in November it will launch 5G fixed wireless services in Canberra and Brisbane this month, with other Australian capital cities to follow by March.

“Using the 5G 3.5 GHz 60 MHz band means that we will be able to deliver greater capacity compared to 4G, enabling the use of multiple devices as well ultra-high definition video streaming which is expected to be key for our customers when 5G begins rolling out this year,” Optus managing director networks Dennis Wong said.

“This is the first time in Australia that a data call has been made using 60 MHz channel bandwidth on an Optus live network and a 5G device.”

Intel Reveals Arc GPU Pricing As It Goes Head-To-Head With Nvidia

Published

on

At $329, the Intel Arc A770 doesn’t directly compete with the RTX 3070, but it’s vying for a spot among the affordable cards that can competently push a smooth 1440p gaming experience — to what effect is anyone’s guess right now. Early benchmarks suggest it should be able to manage under a decent load in most games. In fact, it’s expected to outpace even the 3060 Ti with enough optimization time, and may even come close to the 3070’s potential by the end of its lifecycle, all with less power draw.

Right now, the Arc A770 is the most powerful chip in Intel’s lineup, with equal amounts of both Ray-Tracing and Xe cores for a total of 32 each. It comes in 8GB and 16GB configurations with a 2.1GHz base clock and up to 560MB/s bus speed. Intel suggests it offers a 2x improvement there. We’re not sure which competing GPU it targeted to tout that figure, but we do know it handily beats the RTX 3060, at least according to Intel.

There’s also XeSS, Intel’s highly efficient supersampling technology that should offer sharper graphics and improved antialiasing without major performance hits. We’re said to be seeing up to a 65% performance improvement in that area, but we’re not sure which exact card Intel is judging against. There is a decent list of titles ready to support it at launch, and surely Intel is buttering the palms of its partners to attract more as time rolls on.

LG’s Rollable Phone Is Dead, But Samsung Will Give You A Slidable Screen Instead

Published

on

Choi didn’t go into detail about the screen resolution figures and whether the slideable concept was an OLED panel or an IPS LCD screen. In May 2022, Samsung Display showcased a few screen innovation prototypes, and one among them was a slideable OLED panel. However, it was geared toward phones with an Android UI running on them instead of PCs. We also don’t know if Samsung only plans to sell slideable panels for PCs, or whether it will be the first brand to actually make one such PC. Unlike its foldable smartphones that come in clamshell and tablet hybrid form factors, Samsung has been playing it relatively safe with its lineup of Galaxy Book laptops.

But that’s not where the tale of uncertainty for innovative PC form factors ends. Microsoft hasn’t really been keen on optimizing Windows for crazy form factors like foldables, and now, slideable PCs. In fact, the company abandoned its own ambitious dual-screen foldable PC, the Surface Neo, after announcing it at the 2019 hardware launch event. In fact, Microsoft even dumped the Windows 10X project, which was set to power foldable touchscreen-first PCs like the Surface Neo. With such as shaky history, any OEM on the planet would think twice before burning millions of dollars to make a slideable PC with a poorly optimized operating system to boot.

2023 Bentley Bentayga EWB First Drive: Living Like The Super-Rich

Published

on

Beyond the longer rear doors, what you don’t see are the mechanical changes. This is, Bentley is at pains to point out, no simple stretch of the regular SUV. There’s an entirely new underbody, unique to this Bentayga, and 2,500 or so new parts compared to the existing short wheelbase car. Enough that th automaker is insisting that this is effectively a new, standalone line, rather than just a derivative.

The 4.0-liter twin-turbocharged V8 is carried across, here tuned for 542 horsepower and 568 pound-foot of torque, along with all-wheel drive and an eight speed, dual-clutch transmission. 0-60 mph arrives in 4.5 seconds, Bentley says, just a tenth of a second slower than the standard wheelbase SUV with the same engine. Surging out of tunnels like a silicone-lubed lobster down a length of cast iron pipe, the Bentayga’s healthy torque feels like a happy precursor to the automaker’s all-electric evolution.

Right now there’s no sign of a hybrid Bentayga EWB, or one using Bentley’s mighty W12 engine. The latter propels the Bentayga Speed from 0-60 in a mere 3.8 seconds, and bests the EWB’s 180 miles per hour top speed by another 10 mph, but it’s a heavy powertrain. With the Bentayga EWB V8 already 13 pounds heftier than the Bentayga Speed W12, and a couple hundred pounds more than the regular Bentayga V8, it’s clear that pairing the longer SUV with the twelve-cylinder engine would result in a something even beefier.
