Fujitsu unveils 10Gbps single-panel 5G antenna

Published

Fujitsu Laboratories has unveiled a single-panel antenna designed to enable multiple 5G connections on a small, energy-efficient base station, saying it could be used across train stations and stadiums.

The antenna provides speeds of more than 10Gbps across four simultaneous 2.5Gbps signals, using the millimetre-wave (mmWave) 28GHz 5G spectrum band, with 128 antenna elements, and 16 phased array chips that fit onto a single 13cm square printed circuit board.

“Conventional 5G system structures require use of an antenna panel for each terminal when simultaneously transmitting to multiple terminals. Now, by controlling with high accuracy the phase (angle) of signals separately emitted from 128 antenna elements, Fujitsu Laboratories has suppressed the interference between signals,” the company explained.

“Currently, to avoid radio wave interference during communications with multiple users at once, base stations have been configured to use a number of antenna panels corresponding to the number of concurrent users. To miniaturise the equipment so that it can be deployed anywhere, the best option is to provide multi-directional transmissions from a single antenna panel.”

To achieve this, Fujitsu developed a phased array chip that is able to regulate the phase of a signal propagated with an accuracy of one degree or less from an antenna element. It then built one phased array chip per eight antenna elements into the panel.

“The company also uses circuitry that detects the differences in phase between phased array chips, which enables highly accurate phase control for any size antenna panel that has between 64 and 256 antenna elements,” it said.

“As a result, by holding the difference in undesired emissions intruding between one radio wave communicating with a device and another radio wave with another device to 20dB or more, it makes it possible for a single antenna panel to carry out high-capacity communications of 10Gbps or more.”

Fujitsu is planning to commercialise the technology in 2021.

The announcement follows the company last month signing a 5G partnership with networking giant Ericsson, with plans to combine their radio access and core network portfolios to deliver 5G mobile network services and solutions across Japan.

“Ericsson and Fujitsu’s strength in research and development will ensure the best path for bringing global 5G solutions to Japan, as well as exploring a wider global market,” the companies said in November.

Fujitsu will provide open and standards-based “flexible 5G network systems” using its wireless technology expertise, Fujitsu EVP and head of Network Business Group Tango Matsumoto said.

Fujitsu’s previous work on 5G saw it kick off a field trial last year of its 5G ultra high-density distributed antenna technology and tests of simultaneous high-speed transmission of high-res video using the antenna system, in partnership with Japanese carrier NTT DoCoMo.

Fujitsu and Fujitsu Laboratories, which have been working on 5G trials with NTT DoCoMo since 2014, have also collaborated with the Japanese carrier on evaluating communications speed for distributed antennas deployed at multiple outdoor locations.

“The testing system consists of two mobile stations equipped with displays that can be moved around the interior of Fujitsu Shin-Kawasaki Technology Square, as well as equipment including distributed antennas installed in 16 locations, centralised baseband processing equipment that controls the distributed antennas, and fibre-optic cables connecting the distributed antennas with the centralised baseband processing equipment,” Fujitsu explained in November 2017.

Fujitsu’s ultra-high density distributed antenna technology “actively controls the shape of cells, which are the range of a signal, in order to improve communication quality for mobile stations through centralised control of base station antennas distributed around a space at high density”, it said.

Fujitsu said the 32 distributed antennas can be controlled by the centralised baseband processing devices. This is done by using signal processing equipment that aggregates digital signals — transmitted and received — from several different distributed antennas while preventing signal interference.

Fujitsu also unveiled its millimetre-wave (mmWave) phase shifter for small cells a year ago, which it said delivers the 10Gbps connections required by 5G, while maintaining low power usage.

According to Fujitsu, its phase shifters reduced the number of amps needed by combining switching circuits with differential amps, and using a new mmWave circuit limited the electrical loss of circuits.

Its small cell technology — which Fujitsu said it was looking to offer by 2020 — also makes use of beam-forming, with the company saying it controls 128 antenna elements.

Earlier this month, Fujitsu also said it is working on developing palm vein and facial data authentication technology, with the integrated biometric identification capabilities pointing to a cashless society.

According to Fujitsu, its Laboratories have developed a simulation algorithm enabling instant facial recognition processing.

Callaway Chevy Silverado SC602 Signature Edition trounces Ram TRX in a drag race

Published

on

American performance vehicle builder Callaway Cars has debuted its newest creation: The Chevy Silverado SC602 Signature Edition, now officially the best sleeper truck on the road. How fast? Hold your breath: This Chevy Silverado has trounced the mighty RAM TRX in a drag race. That’s saying a lot since Ram made it clear the TRX is “the quickest, fastest, and most powerful mass-produced truck in the world.”

But as it turns out, Callaway has other plans. The company has a long and cherished history of building quirky yet high-end performance cars like the C4 Corvette Sledgehammer and C7 Corvette AeroWagen. However, what we really love about the Silverado SC602 is the way it looks.

It may resemble a factory-stock Chevy Silverado from some angles, but there are telltale signs of the truck’s outstanding stoplight-to-stoplight ability. Like those 20 or 22-inch Callaway lightweight wheels, for instance, or the bevy of chrome Callaway exterior badging, including a bold CALLAWAY script on the carbon fiber front grille.

As with any Callaway vehicle, what matters most is hiding under the sheet metal. The SC602 starts life as a Chevrolet Silverado Trail Boss, RST, LTZ, or High Country with a standard 6.2-liter V8 motor and four-wheel drive. Next, Callway installs a GenThree Eaton TVS R2650 Supercharger with a TripleCooled intercooler. The blower offers 15-percent more displacement yet requiring 18-percent less power output.

It doesn’t stop there. The truck also gets a high-flow intake, low-restriction stainless steel dual outlet exhausts with quad exhaust tips, and a bespoke Callaway ECU with custom tuning. After all the dirty engine work is complete, the Callaway Silverado SC60’s blown V8 is now pumping out 602 horsepower and 560 pound-feet of torque.

But wait, the Ram TRX’s Hellcat V8 makes 702 horsepower and 650 pound-feet of torque, 100 more horses (and 90 more torques) than Callaway’s truck, so how did it trounce the Ram? Two words: weight and tires. The Silverado SC602 tips the scales at only 5,820 pounds (2640 kg), while the Ram TRX weighs around 7,080 (3,211 kg) pounds.

The result is nothing short of astonishing. The SC602 goes from zero to 60 mph in 4.3-seconds, zero to 100 mph in 9.80-seconds, and breaks the quarter-mile in 12.5-seconds @ 113 mph. Meanwhile, the Ram TRX goes from zero to 60 mph in 3.99-seconds, a bit quicker than the Chevy.

But the latter is faster from zero to 100 mph as the Ram needed 10.14 seconds to perform the deed, proof of the Callaway Silverado SC60’s mid to high-range pulling power. And yeah, those sticky performance tires were partly responsible for the Callaway’s drag strip prowess.

What’s more, the Silverado SC602 is 50-state emissions compliant and carries a 3-year/36,000-mile warranty to supplement Chevy’s bumper-to-bumper warranty. Other goodies include aluminum door sills, billet aluminum pedals, an Alcantara-covered horn cover, and ID plaques to let other people know you’re driving the genuine article.

How much? We have no idea. But you can get in touch with Callaway if you fancy the ultimate Ram-beating sleeper truck.

Ford reveals the custom 2021 Mustang Mach-E to be given away for charity

Published

on

Ford has supported various charities for a long time, often donating customized automobiles to be auctioned off. Each year Ford offers a customized car for the AirVenture charity, and typically that car is a Ford Mustang of some sort with a big V8 engine under the hood. This year, the car Ford is donating to the charity is a different kind of Mustang.

Ford has revealed the customized electric 2021 Mustang Mach-E that will be auctioned off this year. The vehicle was built to honor the sacrifices of Women Air Force Service Pilots. The special Mach-E is inspired by the female volunteer pilots and the planes they flew during World War II.

Proceeds from the vehicle auction support the EAA initiative to provide young women and underserved youths more access to careers in the aviation industry. Ford notes that it has worked with AirVenture for more than two decades and has donated 12 custom aviation-themed performance vehicles so far, raising a total of more than $4 million. 2021 marks the first year Ford has donated an electric vehicle.

The custom Mach-E was designed by Ford and has a custom paint scheme with military badging inspired by the warplanes the volunteers flew. Women Air Force Service Pilots flew almost every type of military aircraft in World War II as they rolled off the factory floor after assembly. Ford put badges, including the US Army Air Force star on both sides, wings logos on the hood and fender, and No. 38 on the front fascia, rear bumper, and inside the cabin.

That number represents the 38 volunteers who died serving their country. Women Air Force Service Pilots are a group of American volunteers who transported warplanes to US Army bases worldwide to be used in combat. The female pilots flew more than 60 million miles during the war and weren’t recognized as active military personnel until 1977 when the pilots were granted retroactive military status.

This Porsche 911 Turbo S pays homage to Mexican driving ace Pedro Rodriguez

Published

on

In collaboration with Porsche Latin America, Porsche Mexico, and Porsche Exclusive Manufaktur, German automaker Porsche has built a custom 911 Turbo S in memory of the late, great Pedro Rodriguez. Rodriguez is the most successful Mexican racing driver of all time.

He walked away with 11 titles in the World Championship of Makes – now known as the World Endurance Championship – and helped Porsche capture the crown in 1970 and 1971 aboard a Porsche 917 KH in Gulf Oil livery. Rodriguez claimed two Formula Grand Prix wins, four wins in the 24 Hours of Daytona, and a victory at the 24 Hours of Le Mans before losing his life in 1971 at the Norising street circuit in Nuremberg, Germany.

Fifty years on after that fateful and deadly crash, Porsche is reliving the glory days with a custom 911 Turbo S ‘One of a Kind’ Pedro Rodriguez. The car debuted at a Sportscar Together Day event at the Centro Alto Rendimineto in Toluca, Mexico, where it drew oohs and ahhs with its custom Gulf attire.

Porsche claims the 911 Turbo S ‘One of a Kind’ Pedro Rodriguez is, well, genuinely one of a kind. “This configuration, with these specific details and equipment, has been locked in the Porsche configurator, as well as in the production system, so that this car is literally unrepeatable,” said Camilo San Martin, Director of Porsche Mexico.

Wearing the iconic Gulf Blue paint with single orange striping, it also has custom high-gloss black wheels, an aluminum center lock, and a black number 2 in a white circle graphic on the doors and front hood. Look closely at the B-pillar and you’ll find a silhouette of the 917 KH race car wearing the colors off the Mexican flag, complete with the name and signature of Pedro Rodriguez.

Other bespoke elements include unique carbon moldings on the lower door frames (which illuminate when the doors are open), Graphite Blue leather seats with orange stitching, and an engraved tribute of the eight races that Rodriguez won aboard the Porsche 917 KH under the rear spoiler.

Also included are a Gulf Blue key fob (with Rodriguez’s signature) and a luggage set wearing the same blue and orange colors. It still has a turbocharged 3.8-liter flat-six pumping out 640 horsepower and 590 pound-feet of torque with an eight-speed dual-clutch gearbox under the hood.

The Porsche 911 Turbo S Pedro Rodriguez will hit the auction block later this year. Porsche will donate the auction proceeds to various charities.
