Wi-Fi Alliance dumps 802.11 naming in favour of version numbers

In a mysterious outbreak of common sense, the Wi-Fi Alliance has dumped the traditional 802.11 naming scheme for Wi-Fi technologies and is pushing ahead with a naming scheme based on numbers.

Under the scheme, 802.11ax becomes Wi-Fi 6, Wi-Fi 5 represents 802.11ac, and Wi-Fi 4 is 802.11n.

Alliance president and CEO Edgar Figueria acknowledged that it had taken almost two decades to create easier monikers for consumers to understand wireless standards.

“The new naming system identifies Wi-Fi generations by a numerical sequence which correspond to major advancements in Wi-Fi,” the alliance said in a blog post.

“The generation names can be used by product vendors to identify the latest Wi-Fi technology a device supports, by OS vendors to identify the generation of Wi-Fi connection between a device and network, and by service providers to identify the capabilities of a Wi-Fi network to their customers.”

The upcoming 802.11ax standard is expected to be 30 percent faster than 802.11ac, and is due for final approval next year.

Along with the renaming, Wi-Fi Alliance released a set of sample icons that showed how users could be notified of which standard their wireless connection is using.

Last month, Korea’s SK Telecom launched a Wi-Fi service based on Wi-Fi 6 and claimed speeds of up to 4.8Gbps were possible. However, flagship handsets with Wi-Fi 6 functionality are yet to be launched.

SK Telecom uses four antennas, spectrum bandwidth of 160MHz across the 2.4GHz and 5GHz spectrum bands for its Wi-Fi.

2021 VW ID.4 electric range gets EPA confirmed – Here’s how it compares

Published

on

Volkswagen’s new all-electric crossover, the 2021 ID.4, has sailed through US EPA testing with no upset in its range results, an important milestone as the automaker tries to make a splash in the affordable EV segment. Arriving at dealerships imminently, the ID.4 is America’s first taste of VW’s MEB platform, its purpose-built architecture for battery-electric vehicles.

That’s a departure from the previous pure-electric models that VW has offered in North America before. The discontinued e-Golf, for example, may have been an EV but it was based on the same platform as the standard, internal combustion version of the car.

MEB, though, was designed from the outset with electric drive alone in mind. Flexible enough to scale down to compact urban hatchbacks and up through luxury sedans to large SUVs, it can also be set up with front-, rear-, or all-wheel drive, and with differing battery pack sizes to balance range, weight, and price. For the first examples of the 2021 ID.4, Volkswagen opted for an 82 kWh battery and RWD, with the single electric motor good for 201 horsepower and 228 lb-ft of torque.

That, the automaker predicted, would work out to 250 miles on the EPA’s test cycle. Sure enough, when the US Environmental Protection Agency published the 2021 ID.4’s numbers – for both the limited-availability ID.4 1st and the ID.4 Pro S, which have the same battery pack – it clocks in at the expected 250 miles.

It’s enough to put the ID.4 firmly in the midst of its electric vehicle segment. Tesla’s numbers remain the range to beat, with the Model Y rated between 291 and 316 miles by the EPA, while Chevrolet’s Bolt EV – a little smaller than the ID.4 – drops in at 259 miles. Ford’s Mustang Mach-E, also just about to arrive at US dealerships, had its range figures certified by the EPA earlier in the week; it will do between 211 and 300 miles, depending on model and drivetrain configuration.

Over at Hyundai, the 2021 Kona Electric is similarly priced to the ID.4, and rated at 258 miles on a charge. Audi’s e-tron and e-tron Sportback, along with the Jaguar I-PACE, are more expensive than the VW, and fall short of its quoted range too – at 220, 218, and 234 miles, respectively – though badge prestige might offset any disappointment there. Volvo’s new 2021 XC40 Recharge and its 2021 Polestar 2 cousin are rated by the EPA at 208 and 233 miles, respectively.

These first two ID.4 models, of course, are only the start of Volkswagen’s assault on the EV space. As well as other configurations of the crossover – including all-wheel drive variants due next year – there’ll be other vehicles based on the MEB platform as the automaker chases its ambitious electric sales goals. Meanwhile, the sticker price of the ID.4 itself is expected to dip too. Though the current cars are being shipped over to the US from Germany, from 2022 VW plans to build the electric crossover in the US as well; the localized, North American-made ID.4 could start from around $35,000 before any credits or incentives.

Bugatti Chiron Sport Les Légendes du Ciel pays tribute to aviation legends

Published

on

Few are aware of Bugatti’s glorious aviation history. Paying homage to ‘The Legends of the Sky’ is a limited run Bugatti Chiron Les Légendes du Ciel based on the Chiron Sport. Only 20 examples of Les Légendes du Ciel are slated for production, and Bugatti is asking $3.42 million (€2.88 million) for each car.

“Bugatti has had close associations with aviation since the company was established more than 110 years ago,” said Stephan Winkelmann, President of Bugatti. Company founder Ettore Bugatti was always fascinated by aviation. Bugatti began developing aircraft engines in 1915. But in 1938, Bugatti began working on the Model 100, a racing aircraft designed to compete in the Deutsch de la Meurthe Cup Race.

“Many successful Bugatti racing drivers, such as Albert Divo, Robert Benoist, and Bartolomeo ‘Meo’ Costantini, flew for the French Air Force, the French aviator legend Roland Garros privately drove a Bugatti Type 18 to be as fast on the road as in the air,” added Winkelmann. “It is therefore almost an obligation for us today to pay tribute to the legends of that time and dedicate a special edition to them.”

As expected, the Chiron Sport Les Légendes du Ciel is brimming with vintage aviation-inspired memorabilia. You’ll find a bevy of aircraft and propeller logos on the seat headrests, front fenders, and center console. The door panels, meanwhile, bear a sketch of a Bugatti Type 13 race car and a Nieuport 17 airplane, the latter of which is a French biplane built in 1916.

All 20 examples of Chiron Sport Les Légendes du Ciel are finished in bespoke Gris Serpent matte gray paint. Other exterior highlights include a gloss white racing stripe, a gloss black front grille surround, and the blue, white, and red colors of the French flag on the side sills.

Meanwhile, the interior is resplendent in fine Gaucho light brown leather and premium aluminum trim. Optional equipment includes comfort seats and a ‘Sky View’ glass roof.

The limited-edition Les Légendes du Ciel Bugatti Chiron Sport remains powered by a gargantuan 8.0-liter W16 turbocharged engine producing 1,479 horsepower and 1,180 pound-feet of torque. Production of this exclusive model will start near the end of 2020.
