Samsung has launched new RFICs and DAFE ASICs that go into 5G chipset, the company announced.

The chips will reduce a 5G base station’s size, weight, and power consumption by 25 percent compared to previous iterations, the company said, increasing efficiency and the ability for rollout. They support 28Ghz and 39GHz spectrum bands.

Samsung has rolled out 36,000 5G base stations across the US and South Korea as of this month.

The company said the new RFICs use 28-nanometre CMOS semiconductor technology, and expand bandwidth maximums to 1.4GHz.

It will launch RFICs that support 24GHz and 47GHz bands later this year.

According to Samsung, the 5G DAFE ASIC can “manage large bandwidths of many that are hundreds of MHz” that can reduce the size and power consumption of this operation.

The South Korean tech giant had vowed in November to expand its market share in wireless network equipment to 20 percent by 2020.

The global telecom market is dominated by Huawei but the Chinese tech giant has been embroiled in the US-China trade row due to security concerns that may see its sales in certain countries blocked.

Samsung also plans to focus on the US and South Korea to build a foundation for further global growth, it has said.

South Korea will roll out 5G for consumers next month, with the tech giant planning to begin sales of a 5G version of its foldable phone, the Galaxy Fold, in its home country in May.

Biden EV plan “the largest mobilization of public investment” since WW2

Published

on

The US government plans to replace its fleet of vehicles with electric alternatives, part of a huge public investment in equipment that President Biden says will be the largest since World War II. The goal was announced today, as Biden discussed the Buy American Executive Order and strategies to strengthen American manufacturing and create jobs in the US.

“The federal government also owns an enormous fleet of vehicles,” Biden said during the press conference, “which we’re going to replace with clean electric vehicles made right here in America, creating millions of jobs, a million autoworker jobs, and clean energy, and vehicles that are net-zero emissions. And together this will be the largest mobilization of public investment in procurement, infrastructure, and R&D since World War II.”

Certainly, there’s no shortage of vehicles being used across the government’s various departments. Each year, those departments are required to submit records on owned, leased, and commercially leased vehicles in their fleets. For 2019, civilian agencies owned more than 158,000 vehicles, while military agencies owned more than 62,000 vehicles.

The biggest fleet, however, is used by the US Postal Service. In the 2019 figures, it reported owning more than 224,000 vehicles. Tallied across all the agencies, there’s more than 445,000 owned vehicles on the books, and more than 200,000 leased in some form, with total costs of around $4.4 billion.

Typically, domestic vehicles already far outweigh the use of foreign passenger vehicles and trucks in use by the US government. Indeed, of the roughly 645,000 strong fleet in 2019, only around 6-percent were foreign-made. However, should even a small percentage be replaced with electrified vehicles, that could represent a huge shift in emissions.

The current reporting does not break down the vehicles by drivetrain type – beyond a separate category for low-speed electric vehicles (LSEV) – so it’s unclear how many might already be battery-electric or hybrids.

Still, it’s only in recent years that there have been viable options for replacing mainstream vehicles with zero-emission alternatives, and even then some categories are still awaiting production EVs. Ford and Chevrolet are both preparing electric pickup trucks, as is Tesla, and several American automakers are working on electric SUVs and sedans.

Startups like Rivian and Canoo are developing both passenger cars and SUVs and electric delivery vehicles, while Ford has an e-Transit in the pipeline, an all-electric version of its best-selling van. Earlier this month, GM announced a new brand, BrightDrop, to focus on electric logistics.

“The dollars the federal government spends on goods and services are a powerful tool to support American workers and manufacturers,” the White House said today. “Contracting alone accounts for nearly $600 billion in federal spending. Federal law requires government agencies to give preferences to American firms, however, these preferences have not always been implemented consistently or effectively.”

Full details of today’s executive order are yet to be published in the Federal Register by the government.

Arcimoto is planning a tilting electric three-wheeler and it sounds epic

Published

on

Get ready for the electric vehicle market to lean over, with Arcimoto announcing it’s acquired a tilting trike specialist to use the tech in future EV three-wheelers. Based in Oregon, Arcimoto currently offers all-electric vehicles for public and business use, with its FUV – or “Fun Utility Vehicle” – available to preorder from around $18k.

Today’s deal sees Arcimoto snap up Tilting Motor Works, which offers a leaning kit for motorcycles. Its TRiO system can adapt existing bikes, promising to keep their natural lean but adding stability with a second front wheel. It’s currently offered for Harley-Davidson, Honda, and Indian models, priced at $14k plus installation.

Now, TRiO will be used for future Arcimoto trikes. The system will allow the EVs to lean into corners for more engaging driving dynamics, as well as lock upright when at a stop. The extra front wheel aids in traction too, Tilting Motor Works says, as well as improving braking; the company will continue to offer its kits for traditional motorcycles as well.

Arcimoto’s current FUV supports two occupants, sitting one behind the other. It has a 75 mph top speed from dual electric motors, and a range of 102 miles of urban driving; the doors are detachable, and rather than a steering wheel inside there are handlebars with heated grips. Currently, the company is taking preorders in Florida and on the west coast of the US.

It’s not the only vehicle Arcimoto has in mind, however. Late in 2020, the company showed off its latest prototype, a three-wheeler it called the ROADSTER. Roofless, and with a chopped-down windshield, it promises a more traditional take on the electric trike segment.

Electric drive and three wheels is arguably where some of the most interesting experiments are taking place in mobility right now. Last month, for example, we took the ElectraMeccanica Solo EV out for a spin, a single-seat electric trike that aims to reboot commuting. Based on the fact that almost 90-percent of Americans typically drive alone, it trades cabin space and seating for much cheaper running costs.

What it doesn’t do, however, is tilt. For an example of that, you have to look to something like Toyota’s i-ROAD, a distinctive electric three-wheeler that could lean into corners according to how aggressively you steered. Offered in select locations in Japan, and part of Toyota’s aggressive electrification push for the next few years, the i-ROAD was never officially offered in the US.

Lotus teases sports car future as Elise, Exige and Evora face the axe

Published

on

Lotus is preparing a huge shake-up, with the iconic British sports car company confirming it’s axing three of its most memorable models to pave way for an all-new line-up. 2021 will be the end of the line for the Evora, Exige, and Elise, Lotus said today, dropping a new teaser about just what is intended to take their place.

We’ve already seen one element of that plan, in the shape of the beastly Evija hypercar. Announced in mid-2019, it promised to tap electrification for its potency, something Lotus demonstrated in action at its public debut in October last year.

Not everyone will be able to afford – or even find a spot on the waiting list for – a $2m+ EV behemoth. For that audience, Lotus has confirmed a new series sports car range, with the Lotus Type 131 expected to go into prototype production later this year.

It’ll be built at the automaker’s Hethel, Norfolk facility in the UK, which will undergo a $127m+ investment and see around 250 more engineers and manufacturing recruits added to the payroll. Helping foot the bill are shareholders Geely and Etika, which took ownership of Lotus in September 2017.

You can’t accuse Lotus of not making the most of its outgoing range. The first-generation Elise made its debut all the way back in 1995, a new model for Lotus but epitomizing its ethos of reducing weight in the name of increasing engagement. Though never the most powerful sport car, it nonetheless carved out a lingering reputation across several generations for its purity behind the wheel.

The Exige, meanwhile, arrived in 2000. A coupe to the Elise’s convertible, it built on the platform with race-focused technology to maximize performance. Come 2008, the Evora gave Lotus an entrant for the super-sports sector, tempering some of the automaker’s notorious focus on paring back creature comforts with a more luxurious, GT-minded approach.

The Type 131 range – part of what Lotus is calling its Vision80 strategy – will include at least three new models, replacing the Elise, Exige, and Evora. “Our renowned team of engineers, designers and technicians who are working on the new cars are acutely aware of the legacy from the Elise, Exige and Evora,” Matt Windle, executive director of engineering at the automaker, says. “Indeed, many were around when Elise was being developed.”

Earlier in 2020, rumors suggested Lotus could reboot the classic Esprit name for a new model. The new Esprit, it was hinted, could use a hybrid V6 powertrain, combining gas and electric power, though unlike James Bond’s car it would be unlikely to turn into a submarine.
