SK Telecom, Samsung, and Cisco to collaborate in 5G smart offices
SK Telecom, Samsung Electronics, and Cisco will collaborate to develop and launch 5G-based smart office services.

SK Telecom will install Dense Wavelength Division Multiplexing (DWDM) equipment on railways in South Korea to boost the data transfer rate on trains from 10Gbps to 100Gbps, the telco has announced.

The company won the order from the Korea Rail Network Authority, a subsidiary agency supervising railways under the Ministry of Land, Infrastructure and Transport, to install the equipment for train lines in the country’s southern regions.

The deal is worth 6.8 billion won ($5.8 million) and the installation deadline will be the end of 2020. SK Telecom will use US vendor Ciena’s fibre solutions for the installations.

The DWDM network will connect LTE-R networks, train control systems, CCTVs, and ticketing systems, SK Telecom said.

This will boost the data transfer rate between them from the current 10Gbps to 100Gbps, and allow seamless communications between on-train staff and control even on express trains running at over 300 kilometres per hour, the telco said.

SK Telecom, together with Samsung Electronics, deployed their first LTE-R network on Busan Metro Line 1 back in 2017. LTE-R networks have since been widely deployed on South Korea’s railways.

Samsung and Japanese telco KDDI has also tested 5G networks for consumers on trains in Tokyo.

Bugatti W16 Mistral Puts A $5 Million Price On The End Of An Era

Published

on

It’s set into a completely new monocoque, Bugatti opting to rework its core platform rather than simply slice off the top of the coupe’s version. The curved windshield wraps around the A-pillars and into the side glass, the top line then flowing into the huge side air intakes. At the front, there’s a sizable horseshoe grille wider than on other Chiron cars.

Two roof-mounted engine air scoops work alongside the oil cooler intakes that are mounted on the side. Separating them allowed Bugatti’s designers to leave the side section of the W16 Mistral slimmer. The scoops have also been made from a custom carbon fiber structure, each of which is strong enough to support the entire weight of the roadster should it flip.

The lighting signature is where the W16 Mistral steps most decisively away from its coupe predecessors. The front has a quad-light signature that doubles as an aero aid, pulling airflow in through the clusters and then out of the front wheel arches. At the rear, the X-theme seen first on the Bugatti Bolide has been updated, here also working as a vent for the side oil coolers.

This Brand Makes The Worst Android Phones, According To 27% Of People We Polled

Published

on

Most respondents who participated in our poll seem to earnestly believe that Xiaomi makes the worst Android phones out there. More than 27% of the polled users think Xiaomi deserves this particular crown. On the face of it, the poll results seem grossly unfair towards Xiaomi, given that the company doesn’t even sell its phones to U.S. consumers. There is no denying, however, that Xiaomi needs to do a lot to change its brand perception in the U.S. if they ever plan on releasing smartphones in North America (again, that is).

With more than 21% of the votes, a virtually unknown smartphone brand for U.S. consumers comes in second place. The brand in question here is Realme — a sub-brand owned by OPPO. Realme is a very popular smartphone brand in Asia and is known mainly for its value-for-money devices that usually compete against similarly priced alternatives from Xiaomi.

Another smartphone brand that is in desperate need of a brand overhaul is Google. More than 18% of polled people thought Google makes the worst Android phones. That’s a lot of brickbats for a company behind the software that powers Android phones. The less favorable opinion seems to stem from a long list of issues that troubled the Google Pixel lineup.

Samsung and OnePlus find themselves in the last two places on this list with 17.23% and 15.54% of the votes, respectively. It could be that the other brands are simply less popular in the minds of U.S. citizens, or it could be that Samsung and OnePlus really and truly make the best Android phones — what do you think?

Lincoln Model L100 Concept Is Hyper-Luxury Electrification With Wild Doors And A Disco Floor

Published

on

Certainly, the exterior of the Model L100 Concept is memorable. Lincoln describes it as “the tension between exuberant elegance and subtle restraint,” and it’s clear that aerodynamics have played a big role in deciding the overall silhouette. We’ve seen how that chase for slipperiness through the air can lead to electric cars looking like relatively amorphous blobs, though that’s something Lincoln manages to avoid.

Instead, it plays with light, glass, and scale. The Model L100 Concept hunkers low to the ground, with a glass panoramic roof and reverse-hinged doors to add drama as well as make entering and exiting more straightforward. Sensors track the owner’s approach, meanwhile, with the promise of a curated light show both outside and inside. Then, the doors — which extend all the way back to the rear bumper — gape outward, while the entire glass roof section lifts up.

The concept is finished with a satin digital ceramic tricot metallic paint, shifting between cool blue and soft white. Instead of the traditional chrome, frosted acrylic has been used as a more sustainable alternative. The whole floor of the cabin, meanwhile, is one big digital panel capable of showing shifting graphics, colors, and patterns.
