5G May Drain Batteries, While Base Stations Will Require Three Times As Much Power (ieee.org) 137

schwit1 quotes IEEE Spectrum: In 2017, members of the mobile telephony industry group 3GPP were bickering over whether to speed the development of 5G standards. One proposal, originally put forward by Vodafone and ultimately agreed to by the rest of the group, promised to deliver 5G networks sooner by developing more aspects of 5G technology simultaneously.

Adopting that proposal may have also meant pushing some decisions down the road. One such decision concerned how 5G networks should encode wireless signals. 3GPP's Release 15, which laid the foundation for 5G, ultimately selected orthogonal frequency-division multiplexing (OFDM), a holdover from 4G, as the encoding option. But Release 16, expected by year's end, will include the findings of a study group assigned to explore alternatives. Wireless standards are frequently updated, and in the next 5G release, the industry could address concerns that OFDM may draw too much power in 5G devices and base stations.

That's a problem, because 5G is expected to require far more base stations to deliver service and connect billions of mobile and IoT devices. "I don't think the carriers really understood the impact on the mobile phone, and what it's going to do to battery life," says James Kimery, the director of marketing for RF and software-defined radio research at National Instruments Corp. "5G is going to come with a price, and that price is battery consumption." And Kimery notes that these concerns apply beyond 5G handsets. China Mobile has "been vocal about the power consumption of their base stations," he says. A 5G base station is generally expected to consume roughly three times as much power as a 4G base station. And more 5G base stations are needed to cover the same area.

Hot Weather Cuts French, German Nuclear Power Output (reuters.com) 249

AmiMoJo quotes Reuters: Scorching temperatures across Europe coupled with prolonged dry weather has reduced French nuclear power generation by around 5.2 gigawatts (GW) or 8%, French power grid operator RTE's data showed on Thursday. Electricity output was curtailed at six reactors by 0840 GMT on Thursday, while two other reactors were offline, data showed. High water temperatures and sluggish flows limit the ability to use river water to cool reactors.

In Germany, PreussenElektra, the nuclear unit of utility E.ON, said it would take its Grohnde reactor offline on Friday due to high temperatures in the Weser river.

France's nuclear reactors supply more than 75% of its electricity, according to the article -- though their grid operator says they still have enough capacity left to meet demand.

Wind Is Outpacing Coal As a Power Source In Texas For the First Time (cnn.com) 276

A new report (XLSX) from the Electric Reliability Council of Texas says wind power has surpassed coal for the first time in the state. CNN reports: Wind has generated 22% of the state's electrical needs this year. It just edged out coal, which provided 21% of the Lone Star State's power, according to the Electrical Reliability Council of Texas, which manages electrical flow on about 90% of the Texan grid. Sixteen years ago, in 2003, wind made up just 0.8% of the state's power, and coal satisfied 40% of electrical needs, the council documents show. By 2010, wind accounted for 8% of the state's energy, and it steadily inched forward to 19% last year and now 22% in the first half of 2019. At the same time, coal's portion of the energy mix has declined over the past several years, from 37% in 2013 to 24% last year and just 21% this year. Yet while wind has soared and coal-generated power has cooled, natural gas still accounts for the largest share of the state's energy mix, generating 46% of its power in 2003 and staying strong at 44% last year.

Leaked Documents Reveal Saudi Arabia's Plans For Its Next Megacity (theverge.com) 138

An anonymous reader quotes a report from The Verge: A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia's biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students. These are only proposals, of course, dreamt up by American consulting firms like McKinsey and Boston Consulting who have no incentive to bring Saudi leaders down to Earth. But all the same, they give you a flavor of what trillions of dollars of oil wealth will do to your sense of proportion.

The whole Neom project is undeniably fascinating. It was first announced in 2017, with Saudi Arabia's de-facto leader, Crown Prince Mohammed bin Salman, saying he wants the city to attract the "world's greatest minds and best talents." According to planning documents reported by the WSJ, bin Salman "envisions Neom the largest city globally by GDP, and wanted to understand what he can get with up to 500 billion USD investment." The project is the flagpole of Saudi Arabia's plans to diversify the country's economy away from oil. MBS and other Saudi leaders known this source of revenue can't last forever, and they're keen to develop cities like Neom as new commercial hubs. As currently planned, Neom will occupy a region the size of Massachusetts. This will include a huge coastal urban sprawl; outlying towns and villages; advance manufacturing hubs in industries like biotech and robotics; and links with international shipping routes. Early building work has already begun, with facilities including a new airport and palace.
Some of the key features of the city include cloud seeding to make it rain, dystopian surveillance to keep citizens safe, genetic engineering to increase human strength and IQ, robot cage fights and "maids," flying taxis, and even a fake moon that could perhaps be created by a fleet of drones or via live-streaming images from space.

The report notes that it's anyone's guess as to whether Neom will live up to its planners' dreams. What may hinder its success is Saudi Arabia's corruption, difficult legal system, and unappealing social norms. "Alcohol is banned; women's rights are restricted; and homosexuality is illegal," the report notes. There's also the sweltering weather that'll only get worse with climate change.

Zen 2 Ryzen IPC Testing Shows AMD Has Closed the Performance Gap With Intel (hothardware.com) 88

MojoKid writes: AMD's new Ryzen 3000 processors can boost as high as 4.6 GHz, a notable bump over previous Ryzen models, but what about AMD's purported Instructions Per Cycle (IPC) gains? Has AMD's Zen 2 architecture finally caught up to Intel's Coffee Lake-based Core series processors in terms of IPC? To prove this out, HotHardware pitted a 12-core Ryzen 9 3900X against Intel's 8-core Core i9-9900K in an array of tests, with both chips locked at 4GHz across all cores and four of the Ryzen CPU cores (or 2 CCXs) disabled (save for a couple of instances to show MT scaling). This allowed AMD's fastest Zen 2-based CPU, with its full 64MB L3 cache complement, to compete against Intel's current fastest desktop chip at identical clock speeds. A series of single-threaded benchmarks were run, in addition to some standard games tests, which are lightly multithreaded. The Intel and AMD multi-core processors essentially traded blows across a number of tests, but Intel won more often than not. The blue team notched IPC wins in SANDRA's Dhrystone integer tests, Geekbench, POV-Ray, LAME MT, and the gaming tests. AMD stole single-threaded victories in SANDRA's Whetstone FPU tests, Cinebench, and Y-Cruncher. While not an outright win for AMD, the company has obviously worked hard to improve 3rd Gen Ryzen IPC throughput, while its multi-core scaling is downright impressive.

Trump Says Apple Will Not Be Given Tariff Waivers or Relief For Mac Pro Parts Made In China (cnbc.com) 210

An anonymous reader quotes a report from CNBC: In a tweet on Friday, President Trump said his administration will not grant Apple any relief on Mac Pro parts made in China. "Apple will not be given Tariff wavers (sic), or relief, for Mac Pro parts that are made in China," President Trump said. "Make them in USA, no Tariffs!" Apple asked for waivers on tariffs on the Mac Pro. Apple said it wanted to be exempt on some parts it uses for the new Mac Pro, including a power supply unit, the stainless-steel enclosure, finished mice and trackpads and circuit boards. "There are no other sources for this proprietary, Apple-designed component," Apple said in a filing. Apple shifted production of the Mac Pro to China in June, saving shipping costs for components that are supplied near Shanghai.

Why DRAM Chipmakers Need Their Own OPEC (bloomberg.com) 132

DRAM is just as much a commodity as oil. But manufacturers can only dream about the benefits of negotiating supply together. From a report: You've got to feel for the world's biggest suppliers of DRAM. Makers of these chips, which temporarily store information in PCs, smartphones and services, endured years of boom-bust profit swings and bruising competition long before the trade war began. The sector finally consolidated into just three companies holding 95% of global supply of DRAM. And yet earnings stability still eludes them. SK Hynix early Thursday posted an 88% drop in second-quarter net income, the lowest in three years and missing estimates. Investors cheered when the South Korean company concurrently announced that it will slow expansion.

SK Hynix supplies around 30% of DRAM. As much as manufacturers would like to tell you otherwise, these chips are all pretty similar, which is why they're considered a commodity. And with most commodities, like oil, prices shift with supply and demand. Profits, in turn, depend on balancing price and supply against the cost of the multi-billion dollar factories required to churn out these chips. It's no easy task. In fact, profitability is as much a function of game theory as capacity and cost management. If you cut supply while your competitor maintains output, prices may rise -- but most of that benefit goes to your rival and you miss out. If no one cuts supply even when demand is falling, then you're all likely to suffer lower prices, which could drag you into the red.

There's a collection of 14 nations well aware of how this works that came up with an ingenious solution: Sit down and negotiate supply together. Except they're peddling oil, not chips, and the Organization of the Petroleum Exporting Countries can't always see eye to eye.

Samsung Galaxy Fold 'Ready' For Launch After Screen Fix (bbc.com) 80

Samsung said it has made the necessary improvements to fix the Galaxy Fold and put it back on sale. The April launch of the device was postponed after early reviewers reported broken screens; it's now scheduled to go on sale in September. From a report: "Samsung has taken the time to fully evaluate the product design, make necessary improvements and run rigorous tests," the company said in a statement. Improvements include extending a protective layer to make it clear it is not meant to be removed, as well as strengthening the hinge area with new protection caps. One explanation for the broken screens appears to have been that some reviewers removed a film which they thought was a typical protective layer that came with the phone when first bought.

World's Largest Nuclear Fusion Experiment Clears Milestone (scientificamerican.com) 161

An anonymous reader quotes a report from Scientific American: A multination project to build a fusion reactor cleared a milestone yesterday and is now six-and-a-half-years away from "First Plasma," officials announced. Yesterday, dignitaries attended a components handover ceremony at the construction site of the International Thermonuclear Experimental Reactor in southern France. The ITER project is an experiment aimed at reaching the next stage in the evolution of nuclear energy as a means of generating emissions-free electricity. The section recently installed -- the cryostat base and lower cylinder -- paves the way for the installation of the tokamak, the technology design chosen to house the powerful magnetic field that will encase the ultra-hot plasma fusion core. The entire project is now 65% complete, the officials said. "Manufactured by India, the ITER cryostat is 16,000 cubic meters," ITER officials said in a release. "Its diameter and height are both almost 30 meters and it weighs 3,850 tons. Because of its bulk, it is being fabricated in four main sections: the base, lower cylinder, upper cylinder, and top lid."

Ford Teases All-Electric F-150 Pickup Truck By Pulling a Million-Pound Train (theverge.com) 143

An anonymous reader quotes a report from The Verge: In 2017, Ford announced that it would sell an all-electric version of its best-selling F-150 pickup truck. It plans to start selling a hybrid version in 2020, and as a way to start priming the pump (or plug, as it were) for a vehicle that will no doubt be a very big deal, the company released a video Tuesday demonstrating the electric truck's remarkable towing capacity. The electric prototype is seen pulling 10 double-decker rail cars over 1,000 feet. It does it once when the rail cars are empty and a second time with them loaded with 42 regular, gas-burning F-150s. The latter stunt puts the entire load at 1.25 million pounds, according to Linda Zhang, chief engineer on the electric truck project. In the fine print, Ford describes the towing stunt as a "one-time short event demonstration" and claims it is "far beyond any production truck's published capacity." Right now, Tesla holds the record for pulling the heaviest load, when a Model X towed a 287,000-pound Boeing 787-9 Dreamliner nearly 1,000 feet on a taxiway at the Melbourne Airport in Australia last year. In June, Elon Musk teased Tesla's upcoming Pickup truck and took a swipe at Ford and other truck companies, saying: "It's going to be a truck that is more capable than other trucks. The goal is to be a better truck than a [Ford] F-150 in terms of truck-like functionality and be a better sports car than a standard [Porsche] 911. That's the aspiration."

He also said in a tweet that the towing capacity would be 300,000 pounds.

Dropbox Irks Mac Users With Annoying Dock Icon, Offers Clueless Support (arstechnica.com) 67

An anonymous reader quotes a report from Ars Technica: Dropbox now opens a new file browser and an associated Dock icon every time it starts, even if you don't want it to. If you're not familiar with Macs, the Dock is the line of applications on the bottom of the screen (or the side, if you've moved it in the settings) and serves the same function as the Windows Taskbar. If my computer restarts or if Dropbox restarts, the new Dropbox window that I don't want pops up in the Dock. This isn't a huge deal, as I can quit Dropbox's new file browser and get rid of that Dock icon each time my computer starts up. I'm not going to stop using Dropbox -- I've been paying the company $138 a year for 2TB of storage and for 12 months' worth of file history, which saves all deleted files and revisions to files. (It's going up to $158 next time I get billed, in February.) It's worth it to me because Dropbox still works great, while the alternatives have always been unreliable or disappointing in other ways when I've tried them. I'll get into that more later in this article.

But the Dock icon and window is a major change in how Dropbox presents itself to users. Dropbox has always been the kind of application that is there when you need it and gets out of the way when you don't. Dropbox's syncing and file-sharing features are integrated with the Finder (the Mac file manager), and there's a little icon in the Mac's Menu Bar at the top of the screen for when you need to change a setting. But now, Dropbox wants to be front and center at all times. The company built its own file browser to replace what's already available in the Mac Finder, and it opens that new file manager every time Dropbox starts. We wrote about it last week when Dropbox started rolling it out to more users. I've had it for more than a month since I somehow ended up in Dropbox's Early Access program.
Ars' Jon Brodkin, the author of the article, also discovered that "there are numerous Dropbox support employees who apparently have never used their company's Mac application and do not understand how it works." Specifically, the employees Brodkin talked to didn't know "that it's possible for Mac applications to run without a Dock icon even though that's exactly how Dropbox worked for a decade... And they've been giving bad advice to users who want to change back to the old way of doing things."

MicroLED Displays Could Show Up In Products As Soon As 2020 (ieee.org) 50

An anonymous reader quotes a report IEEE Spectrum: One of the most striking things about the prototype microLED display that Silicon Valley startup Mojo Vision unveiled in June was its size. At half a millimeter across, it's barely bigger than a single pixel from the microLED TV prototype Samsung showed off in 2018. That both use versions of the same technology is remarkable, and it portends big potential for screens made of superefficient and bright micrometer-scale gallium nitride LEDs. Impressive prototypes have proliferated during the past year, and now that companies are turning to the hard work of scaling up their manufacturing processes, displays could appear in some products as soon as late next year. The driving force behind microLED displays remains a combination of brightness and efficiency that LCD and OLED technology can't come close to. One demo of a smartwatch-size display by Silicon Valley -- based Glo shines at 4,000 nits (candelas per square meter) while consuming less than 1 watt. An equivalent LCD display would burn out in seconds trying to meet half that brightness. Some companies "are making monolithic displays, where the gallium nitride pixels are made as a complete array on a chip and a separate silicon backplane controls those pixels," the report says. Others "are using 'pick and place' technology to transfer individual LEDs or multi-microLED pixels into place on a thin-film-transistor (TFT) backplane. The former is suited to microdisplays for applications like augmented reality and head-up displays. The latter is a better fit for larger displays."

Asus Unveils High-End 'ROG Phone II' Smartphone With 120Hz Display, Snapdragon 855 Plus, and Giant Battery (phonedog.com) 102

Asus has unveiled a spec-heavy gaming phone called the ROG Phone II. When it launches later this year, it'll be one of the only phones to feature Qualcomm's new gaming-focused Snapdragon 855 Plus processor, a 120Hz AMOLED display, and massive 6,000mAh battery. PhoneDog reports: The ROG Phone II features a 6.59-inch 2340x1080 AMOLED display with a 120Hz refresh rate and it's the first phone to include Qualcomm's gaming-focused Snapdragon 855 Plus processor. Both the CPU and GPU in the SD855 Plus are clocked higher than in the standard SD855, helping you get better performance. ASUS has crammed 12GB of RAM inside the ROG Phone II's body, too. Another gaming-centric feature of the ROG Phone II are its AirTrigger buttons. Located on the side of the device, they give you extra buttons for your games and an improved software algorithm over the first ROG Phone that lets you rest your fingers on the AirTriggers, meaning you can react more quickly since you're not having to move your fingers to reach for the buttons.

Other notable features of the ROG Phone II include a 48MP main camera with Sony IMX586 sensor, a 13MP ultra wide rear camera with a 125-degree field of view, and a 24MP front camera. There's up to 512GB of built-in storage available, an in-display fingerprint reader, dual front-facing speakers, and a 3.5mm headphone jack. Powering the whole package is a whopping 6000mAh battery. There are two USB-C ports on the ROG Phone II, with one in a traditional place on the bottom of the device and the other on the side of the phone so that it doesn't get in your way when you're gaming and charging. Both ports support Quick Charge 3.0, but the side port can charge more quickly with QuickCharge 4.0 support. It also includes support for 4K video output using DisplayPort 1.4.
We don't have an official price or release date yet, but it's likely to start shipping later this year at around $899, which was the cost of the original ROG Phone.

Apple In Advanced Talks To Buy Intel's Smartphone-Modem Chip Business (cnbc.com) 64

According to The Wall Street Journal, Apple is in advanced talks to buy Intel's smartphone-modem chip business (Warning: source paywalled; alternative source), "a move that would jump-start the iPhone maker's push to take control of developing the critical components powering its devices." From the report: A deal, covering a portfolio of patents and staff valued at $1 billion or more, could be reached in the next week, the people said -- assuming the talks don't fall apart. Though the purchase price is a rounding error for companies valued in the hundreds of billions of dollars, the transaction would be important strategically and financially. It would give Apple access to engineering work and talent behind Intel's yearslong push to develop modem chips for the crucial next generation of wireless technology known as 5G, potentially saving years of development work.

For Intel's part, a deal would allow the company to shed a business that had been weighing on its bottom line: The smartphone operation had been losing about $1 billion annually, a person familiar with its performance has said, and has generally failed to live up to expectations. Though it would exit the smartphone business, Intel plans to continue to work on 5G technology for other connected devices.
Earlier this year, it was reported that Apple began discussing plans to acquire parts of Intel's smartphone modem chip business last summer, around the time former Intel Chief Executive Brian Krzanich resigned. "Mr. Krzanich championed the modem business and touted 5G technology as a big future revenue stream," reports The Wall Street Journal. "When Bob Swan was named to that job in January, analysts said the odds of a deal rose because his focus on cleaning up Intel would require addressing the losses in the modem business."

DRAM Prices To Slide More Than 40% in 2019 Because Chip Makers Can't Forecast (theregister.co.uk) 81

The laws of botched supply and demand forecasting are coming home to roost for the semiconductor industry in 2019 with DRAM average sales price set to fall 42.1 per cent. From a report: The latest ladle of doom and gloom was poured onto the sector this morning by Gartner, days after IC Insights delivered its dark prognosis for chip makers. "A weaker pricing environment for memory and some other chip types combined with the US-China trade dispute and lower growth in major applications, including smartphones, servers and PCs is driving the global semiconductor market to its lowest growth level since 2009," said Gartner analyst Ben Lee. [...] The upshot of this is that global semiconductor revenues are expected to drop 9.6 per cent year-on-year to $475bn. This is down 3.4 per cent on Gartner's earlier forecast and likely could be revised again before the end of 2019 is upon us. Given the volumes of DRAM swilling around the supply chain that have forced down price, oversupply is on track to spill into the first and second quarters of the next calendar year.

Dropbox Brings Back Support For ZFS, XFS, Btrfs And eCryptFS On Linux (linuxuprising.com) 69

Speaking of Dropbox, the online storage cloud service has enabled support for ZFS and XFS on 64-bit Linux systems, and eCryptFS and Btrfs on all Linux systems. The move comes after it recently pulled support for all file storage systems on Linux except Ext4. From a report: Dropbox stopped supporting folder syncing to drives with filesystems it deemed "uncommon", which on Linux meant anything but Ext4, upsetting quite a few users. The reason cited for this was that "a supported file system is required as Dropbox relies on extended attributes (X-attrs) to identify files in the Dropbox folder and keep them in sync", which doesn't really make sense since there are many filesystems that support xattr (extended attributes) on Linux. After this change was announced, various workarounds started to appear online, including one that I posted on Linux Uprising. There was even a new unofficial, open source Dropbox client developed for this reason (which is also much lighter than the official client by the way). But this didn't last long though, as last week, the Dropbox 77.3.127 beta changelog says that Dropbox has added back support for ZFS (on 64-bit systems only), XFS (on 64bit systems only), Btrfs and eCryptFS.

Samsung-Backed Researchers Develop a Ternary Semiconductor (zdnet.com) 164

"Future semiconductors may perform logic with 0, 1, or 2 instead of the current binary system of 0 and 1," reports ZDNet: A South Korean research team has successfully realised an energy-efficient ternary metal-oxide semiconductor on a large-sized wafer. Professor Kyung Rok Kim of UNIST's Electrical & Computer Engineering Department and his team successfully created a semiconductor that operates in a ternary logic system instead of the current binary...

Using the ternary system of 0, 1, 2 lessens the amount of information semiconductors need to process and does it faster, resulting in less power consumption, the team said. It will also help in miniaturising chips further. For example, to express the number 128 in the current binary system, 8 "bits" will be required. With the ternary system, only 5 "trits" will be required....

Samsung Electronics has been backing Kim's research since September 2017 via its Samsung's Science & Technology Foundation, which offers grants for promising technology projects. Samsung is currently verifying the technology at its foundry business-run fab.

Largest Hybrid Electric Plane Set To Take Flight (zdnet.com) 68

Ampair, a Los Angeles clean tech company in my neck of the woods, is set to begin accepting orders for a hybrid electric aircraft at the EAA AirVenture airshow in Wisconsin next week. Dubbed the EEL, the aircraft is in fact a retrofit of a Cessna 337, an aircraft that has a forward-mounted prop engine that pulls and a rear-mounted prop engine that pushes. Ampair's retrofit will replace one of those internal combustion engines with an electric motor powered by batteries. ZDNet reports: Ampair believes hybrid power may be a stopgap, providing fuel savings while still retaining many of the benefits of an internal combustion drivetrain. "The Ampaire Electric EEL is the first step in bringing lower emissions, lower-operating costs, and quieter operations to general aviation through electrification," according to the company's CEO Kevin Noertker. "The original Cessna 337 provided great utility, and this hybrid electric conversion retains those advantages while reducing fuel cost and maintenance by about 50 percent." The EEL is now undergoing a 30 month test program, which began in June. One of the tests will be demonstrating reliable single-engine climbs on each powerplant. Ampair expects the aircraft to be certified by 2021. Ampair's EEL aircraft will seat four or six passengers. The company says the aircraft cost will be competitive with comparable piston twins.

Quantum Leap From Australian Research Promises Super-Fast Computing Power (theguardian.com) 68

An anonymous reader quotes a report from The Guardian: Simmons, a former Australian of the Year, and her team at the University of New South Wales announced in a paper published in Nature journal on Thursday that they have been able to achieve the first two-qubit gate between atom qubits in silicon, allowing them to communicate with each other at a 200 times faster rate than previously achieved at 0.8 nanoseconds. A two-qubit gate operates like a logic gate in traditional computing, and the team at UNSW was able to achieve the faster operation by putting the two atom qubits closer together than ever before -- just 13 nanometers -- and in real-time controllably observing and measuring their spin states. A scanning tunneling microscope was used to place the atoms in silicon after the optimal distance between the two qubits had been worked out. The research has been two decades in the making, after researchers in Australia opted to build a quantum computer on silicon material.
