Satellite antenna companies divided on near-term feasibility of cheap flat panels - SpaceNews.com Oct 2018
"Builders of satellite antennas disagree on whether flat panel antennas — widely considered a necessity for planned broadband megaconstellations — can be produced cheaply enough to address the mass consumer market in the near term. Antenna makers say so much enthusiasm exists for such antennas that sorting fact from wishful thinking among buyer expectations and seller claims has become a difficulty all its own. "

"“We’ve all heard the crazy requests from some operators asking for millions of antennas for multiple hundreds of dollars,” said Drew Klein, director of international business development at C-Com Satellite Systems, a company that builds dish antennas and is working on a flat panel antenna with the University of Waterloo. Such prices are achievable “within the next decade” — and have to be, he said, in order to address new markets. "

"Some antenna companies, like Israel-based Gilat Satellite Networks, are focused first on building flat panel antennas for customers who are willing to pay higher prices than consumers. "

“I think we are a long ways away from seeing a consumer flat panel antenna in the couple-of-hundred-dollars price point, which is where it needs to be to compete with consumer terminals that we have today for [high-throughput] satellites,” said Andre Jones

"In the absence of commercial flat panel antennas, SES has been forced to rely on two dish antenna systems with mechanical steering to keep constant links with O3b satellites in 8,000-kilometer medium Earth orbits, but this approach is very expensive. "

"John Finney, Isotropic CEO, said his company is making progress on an antenna designed to fit within a $300 to $700 price range stipulated by OneWeb"

"Kymeta antennas are priced up to $39,000 today, though the company plans to drive those prices down to below $1,000 through volume."

Spectrum assignments need a rethink, say academics | PolicyTracker Oct 2018
"Academics and telecoms industry representatives recently discussed the future of spectrum auctions in a seminar on New directions in spectrum assignment for 5G hosted at French graduate engineering school Telecom ParisTech. They concluded that there is a need to rethink assignment policies to help achieve wider economic and social policy goals. "

Thieves steal a Tesla Model S by hacking the entry fob - Engadget Oct 2018
"A Tesla owner who recorded thieves stealing his Model S by hacking the passive entry system has published the video on YouTube so we can all watch (and learn). It shows the crooks using a tablet to apparently capture the passive signal from his keyfob, then using the data to open the vehicle. "

"Tesla has recently implemented features to deter passive entry theft, but the owner sheepishly admitted he didn't use them. Namely, he failed to activate the "PIN to drive" feature that requires a further code before you can drive off. He also left passive entry -- which opens the car when you walk up to it with the fob -- enabled, even though it was parked outside. He also didn't use a "Faraday pouch" to store the fob, which would have prevented the thieves from nabbing the signals."

The Legend of Pope Joan - Footnoting History, Sep 2018
Fantastic commentary at the end about why conspiracy theories occur

"One of the most famous stories about the medieval papacy is that, supposedly sometime in the 9th or 11th century, there was a woman named Joan who disguised herself as a man and became Pope John. While it might sound like a modern, anti-Catholic creation, this story was actually invented in the Middle Ages. In this episode, Nathan returns to the realm of medieval conspiracy theories to talk about the medieval origins and development of the myth of Joan, as well as the social role of conspiracy theory."

"Microsoft has announced that the next major update to Windows 10 will run its Edge browser in a lightweight virtual machine. Running the update in a virtual machine will make exploiting the browser and attacking the operating system or compromising user data more challenging."

"The Edge browser already creates a secure sandbox for its processes, a technique that tries to limit the damage that can be done when malicious code runs within the browser."

"Credential Guard's virtual machine is very small and lightweight, running only a relatively simple process to manage credentials. Application Guard will go much further by running large parts of the Edge browser within a virtual machine."

"As with other VBS features, Application Guard will also only be available to users of Windows 10 Enterprise, with administrative control through group policies"

C-band Spectrum Reallocation: Too Lucrative to Ignore? - NSR Oct 2018
"While various countries have already implemented several measures to either purchase or forcefully take the band from satellite operators and auction off to telecom operators, the case in U.S. has been more uncertain until last year."

"The majority rights holders to 3.7-4.2 GHz of spectrum in the U.S. are Intelsat and SES, two major, global satellite operators in terms of in-orbit satellites and transponders leased. They account for almost ~90% of the U.S. C-band spectrum and service various cable customers across the U.S. for video distribution. However, with spectrum rights expected to expire in mid 2020s and YoY performance on the C-band U.S. business declining fast"

"with the new compression HEVC using DVB-S2X, almost all video distribution channels could fit in under 30% of Ku-band satellite capacity."

Does the satellite industry have antenna deficit disorder? - SpaceNews.com Oct 2018
"To connect the masses, megaconstellations will need mega antennas mega cheap. Antenna makers need mega orders to make that happen."

David Hartshorn: “There are business plans, big ones, hanging out there that depend if not entirely then at least to a very large extent on the availability of high-performance, low-cost, high-volume, low-profile antennas,”

"Northern Sky Research expects companies to ship 1.8 million flat panel antennas between now and 2027 with revenues topping $8 billion for the decade."

"For years, antenna manufacturers have produced high-performance alternatives to gimbaled parabolic antennas pointed at geostationary communications satellites. Price tags range from a few thousand dollars to $250,000 depending on the application."

"To work with low Earth orbit constellations, the antennas need to track two or more satellites simultaneously — something parabolic dishes can’t do. They also need to be small and durable, prevent signal interference, instantly find satellites and secure links, degrade gracefully and have great signal efficiency.

“It turns out that according to the laws of physics, you cannot do all those things at the same time,” said Ralph Brooker, president of SatProf"

John Finney, Isotropic: “What OneWeb wants in terms of target price is in the very low hundreds of dollars. We see a way to get there.”

Antenna builder ThinKom makes push for constellation market - SpaceNews.com Oct 2018
"ThinKom tested a phased array antenna with SES in August, practicing links with O3b satellites in medium Earth orbit as they rose over the horizon and then tracking them for 30 minutes each.

"Last month, ThinKom and Telesat announced plans to test an antenna with a Telesat prototype satellite in low Earth orbit (LEO) and to collaborate on business-grade terminals for Telesat’s planned 120-satellite LEO constellation. "

"The absence of such flat-panel antennas, as constellations start launching and high-throughput geostationary satellites grow in number, has satellite operators “all pretty much desperate to see somebody bring a solution to market,” according to Chris Quilty, president of Quilty Analytics. "

"ThinKom is best known for its ThinAir Ku3030 antennas that inflight connectivity provider Gogo builds into its 2Ku airplane Wi-Fi terminals. ... Bill Milroy, ThinKom’s chairman and chief technical officer, said his company intends to use the same phased array technology it has used for antennas on aircraft "

"SES is attempting to cultivate commercially viable flat-panel antennas for O3b mPower, its next-generation constellation, having contracted with Viasat, Alcan Systems and Isotropic Systems last year to build electronically steered antennas. "

"ThinKom’s approach differs from SES’s other three partners in that its antennas don’t use electronic steering, despite being relatively flat. The aeronautical antenna it is testing with SES is 20 centimeters thick and uses mechanical systems to track satellites. "

"Whereas a ThinKom antenna requires around half a second to switch satellites, an electronically steered antenna has the potential to switch in microseconds"

"ThinKom is targeting $10,000 for enterprise, or business-grade, terminals. ... For consumer terminals, ThinKom is targeting “sub-$1,000” prices."

South Florida’s Hurricane Building Code is Strong—And North Florida’s Could Be Stronger by Bob Henson | Category 6 | Weather Underground
"Figure 1 (below) shows the 3-second wind gusts used in Florida since 2010 to set the minimum building code that applies to most homes and other structures apart from hospitals and other health care facilities. These values were calculated based on extensive computer modeling and observations, drawing in part on the state’s multiple hurricane landfalls in 2004. They’re designed to represent the highest gusts one would expect to recur at a given point in a typical 700-year period."

Can apply to spectrum statistics: uses combination of "extensive computer modeling and observation"

From Sun Sentinel quote: '' Insurance Journal added: “The shift toward less rigorous codes is driven by several factors, experts say: Rising anti-regulatory sentiment among state officials, and the desire to avoid anything that might hurt home sales and the tax revenue that goes with them. And fierce lobbying from home builders.” ''

In reproducing quantum phenomena without any of the mystery, the bouncing-droplet experiments rekindled in some physicists de Broglie’s old dream of a reality at the quantum scale that consists of pilot waves and particles instead of probability waves and conundrums.

Chill factors: The everyday things that make us see ghosts | New Scientist Nov 2017
"Over the years, researchers have singled out various physical, psychological and environmental factors. But debate continues about which ones are actually involved, how they create ghostly experiences and why some of us are more affected than others."

" In the early 1900s, British radio pioneer Oliver Lodge linked physical vibrations to reports of psychic phenomena. Others have since pointed the finger specifically at infrasound – sounds below the normal limit of human hearing – and electromagnetic fields. .... But other studies have been inconclusive."

" in 2009 by a team at Goldsmiths, University of London, who built a room to investigate environmental factors linked to ghostly encounters. Participants in the Haunt project reported plenty of “anomalous” sensations, ranging from tingling and sadness to sensing a presence, terror and even sexual arousal. However, there were no peaks in these effects close to planted sources of infrasound, and they were just as common when the infrasound was off as when it was on."

"The case for electromagnetic fields is less compelling, but O’Keeffe suspects infrasound does have a role in experiences of haunting. ... Context is crucial, though. "

"Some clues come from neurological patients who report feeling someone is there when no one is actually present. Olaf Blanke [et al.] examined some of them, and traced their experiences to lesions in parts of the brain involved in sensorimotor control: ... In particular, damage in any one of three brain areas resulted in the misperception of “self” as “other”."

“Our study shows that the brain has multiple representations of our own body,” says Blanke. “Normally, these are successfully integrated, giving us a unitary experience of our body and self. However, when the brain network is damaged, a second representation of our body – different from our physical body – may arise, which is not experienced as ‘me’ or ‘I’, but rather as the presence of another human being.” He notes that at high altitudes, a lack of oxygen could affect the temporoparietal junction, one brain region his team identified as playing a role in sensing a presence. Physical exhaustion could do so too. “Due to its direct link with sensorimotor processing, it could impact the brain regions we described,” says Blanke.

Large Majorities Dislike Political Correctness - The Atlantic Oct 2018
"On social media, the country seems to divide into two neat camps: Call them the woke and the resentful. "

"Reality is nothing like this. As scholars Stephen Hawkins, Daniel Yudkin, Miriam Juan-Torres, and Tim Dixon argue in a report published Wednesday, “Hidden Tribes: A Study of America’s Polarized Landscape,” most Americans don’t fit into either of these camps. They also share more common ground than the daily fights on social media might suggest—including a general aversion to PC culture."

"If you look at what Americans have to say on issues such as immigration, the extent of white privilege, and the prevalence of sexual harassment, the authors argue, seven distinct clusters emerge: progressive activists, traditional liberals, passive liberals, the politically disengaged, moderates, traditional conservatives, and devoted conservatives."

"According to the report, 25 percent of Americans are traditional or devoted conservatives, and their views are far outside the American mainstream. Some 8 percent of Americans are progressive activists, and their views are even less typical. By contrast, the two-thirds of Americans who don’t belong to either extreme constitute an “exhausted majority.” Their members “share a sense of fatigue with our polarized national conversation, a willingness to be flexible in their political viewpoints, and a lack of voice in the national conversation.”"

"Three quarters of African Americans oppose political correctness."

"If age and race do not predict support for political correctness, what does? Income and education. ... Political tribe—as defined by the authors—is an even better predictor of views on political correctness."

"The gap between the progressive perception and the reality of public views on this issue could do damage to the institutions that the woke elite collectively run. "

" As one 57- year-old woman in Mississippi fretted:

The way you have to term everything just right. And if you don’t term it right you discriminate them. It’s like everybody is going to be in the know of what people call themselves now and some of us just don’t know. But if you don’t know then there is something seriously wrong with you."

Satellite Big Data 3L’s: Location, Location, Location — NSR's Big Data Analytics , Satnews Daily Sep 2018
Article by Shivaprakash Muruganandham, NSR Analys

"NSR’s Big Data Analytics via Satellite, 2nd Edition report identifies seven vertical markets as growth areas, and more than 70 percent of the share is held by the Transportation, Government and Military (Gov/Mil) and Energy markets throughout the forecast period."

Transportation

"The mobile nature of the transportation segment ensures that it remains important throughout the next decade, with nearly 1 out of every three dollars spent on SBD coming from land, maritime and aeronautical transport segments."

Government & Military

"NSR finds growth in this sector to be largely driven by the rise of geospatial intelligence (GEOINT), with EO applications growing at nearly twice the rate of M2M/IoT SATCOM applications"

Energy

"M2M/IoT SATCOM will continue to play a major role in Energy, due to the remote nature of asset locations and the absence of terrestrial solutions."

"NSR’s considers that EO satellite-based analytics services are expected to grow in importance for this vertical, despite competition from unmanned aerial system (UAS) alternatives. This growth will be fueled by the rise of new sensing capabilities such as methane tracking and emissions monitoring solutions for O&G companies looking to mitigate financial risks."

(great animation from ESA, and Nature infographic)

"Several teams are trying to improve methods for assessing what is in orbit, so that satellite operators can work more efficiently in ever-more-crowded space. Some researchers are now starting to compile a massive data set that includes the best possible information on where everything is in orbit. Others are developing taxonomies of space junk — working out how to measure properties such as the shape and size of an object, so that satellite operators know how much to worry about what’s coming their way. And several investigators are identifying special orbits that satellites could be moved into after they finish their missions so they burn up in the atmosphere quickly, helping to clean up space. "

Radio Frequency-Activity Modeling and Pattern Recognition (RF-AMPR) | SBIR.gov 2018
"OBJECTIVE: The PMW 120 Program Office desires a Radio Frequency Activity Modeling and Pattern Recognition (RF-AMPR) capability to perform pattern recognition, anomaly detection, and improved clustering of radio frequency (RF) signals. Specifically, it shall consist of a parametric RF classifier, a generative model of activity in the local electromagnetic environment, a machine learning-based anomaly detection method, and an RF data-clustering algorithm that classifies data that would otherwise be discarded by the parametric classifier."

"DESCRIPTION: Current automated RF data analysis and information discovery methods necessitate discarding significant volumes of sensor data as “non-analyzable”. This SBIR topic seeks to apply machine learning methodologies to better characterize this discarded data, enabling a more complete understanding of RF activity present in a specific environment."

"Anomaly classification shall include “known unknowns”, radio frequency events that are outliers of known classes, and “unknown unknowns”, anomalous RF events that represent new devices or activities."

Expert Commentary: The Dark Side of Detect and Avoid - Inside Unmanned Systems, Mar 2018
"Your task is to penetrate U.S. air surveillance networks, slip drones into American airspace and spy on critical infrastructure like dams, power plants, factories, etc. "

"EASY WAY NO. 1: Simply have 3PLA, the Third Department of the People’s Liberation Army’s General Staff Department—China’s equivalent to the U.S. NSA. hack into the databases of the NASA-designed future Unmanned Traffic Management (UTM) system to get fine-grained ground based DAA (GBDAA) data from the hundreds of radars that will be connected to UTM.... find out which companies are flying near your targets of interest, ... and then get 3PLA to hack into the target’s imagery servers. "

"EASY WAY NO. 2: This option is a bit more expensive, but gives you more control over the intelligence gathered. You do all the steps from easy way No. 1, but instead of just waiting, you take over their drone and gather your own imagery"

"EASY WAY NO. 3: Put your own data links on buildings near targets and take over drones to do your spying. A drawback to easy way No. 2 is that cell phone company cyber security is actually quite good, making it tough to hack into their network and fly them from China directly. Easy way No. 3 gets around cell phone company security by simply taking direct control of unwitting American drones. ... There’s a chance that upcoming airworthiness standards for beyond line of sight (BLOS) drone operations will err on the side of reliability and toss security out the window ... links that don’t ask too many questions when lost also don’t care if a slightly higher powered antenna takes over from their original ground station and gives their drone orders for a bit."

"EASY WAY NO. 4 (THIS SHOULD PROBABLY BE CALLED DEAD EASY WAY NO. 1): Start your own drone critical infrastructure inspection front company and make money while you spy!"

"The cell phone companies already have impressive cyber security for the relay portion of the network; your cell phone calls are very secure while they’re being relayed between cell towers. The problem remains with the drone data links themselves. The FAA simply must write drone command and communications standards that give link reliability and security equal footing."

"The issue will be the sheer volume of vetting required to manage the same level of security screening for the unmanned aviation business community."

6 Great Uses for Contruction Drones - Dronethusiast
Uses For Drones in Construction Projects
= Drone For Surveying
= Inspection: "compare the model of the existing site with the design file, and the final product was a very useful heat map that showed the external contractor’s progress in amazing detail"
= Showing Clients the Progress
= Monitoring Job Sites
= Inspecting Structures - deterioration
= Better Safety Records - "When you can use drone imaging to show erection sequences, crane locations, and perimeter security like fencing, you can view them repeatedly to pinpoint where projects begin to get congested, and even predict where hazards could pop up"
= Keeping the Project On-track, On-Budget

Philippines aims to choose third operator by the end of 2018 | PolicyTracker Oct 2018
"It may have taken nearly a decade but the Philippines is close to ending its long-running duopoly. It is using a novel approach to achieve this. "

"The selection criteria are population coverage, minimum average broadband speed and capex/opex spend with a weighting of 40 per cent, 25 per cent and 35 per cent respectively counting towards the final score.

“It’s a quasi-auction approach, only instead of bidding with money, you bid with coverage, speed and capex/opex,” said Kas Kalba, founder of advisory firm Kalba International."

"Like an auction, the Philippines approach offers the opportunity for aggressive bidding, particularly on coverage and capex/opex, Kalba said."

"Consumer pricing is not included as one of the three criteria, which must be a relief to the two incumbents fearful of a disruptive newcomer. "

"Monitoring broadband speeds can be a tricky business but, under the Philippines’ plan, it will be done by an independent auditor, who will also establish whether the licence winner is meeting the coverage terms included in its bid."

"In the final analysis, the winner risks losing a performance security placed with the NTC – worth 10 per cent of the remaining cumulative capex and opex commitment – if they fail to deliver."

"This year, DICT won a battle against the Department of Finance’s proposal for an auction based on the highest financial bid, paving the way for the current process."

It's Time to Slow Digital Credit's Growth in East Africa | CGAP Oct 2018
"CGAP has now gathered and analyzed phone survey data from over 1,100 digital borrowers from Kenya and 1,000 borrowers from Tanzania. We have also reviewed transactional and demographic data associated with over 20 million digital loans (with an average loan size below $15) disbursed over a 23-month period in Tanzania. Both the demand- and supply-side data show that transparency and responsible lending issues are contributing to high late-payment and default rates in digital credit."

The ROI Challenge of IoT Smallsats - NSR, Oct 2018
"In the recently released M2M and IoT via Satellite, 9th Edition report, NSR projected over 3.7 million smallsat IoT in-service units by 2027; this will generate approx. $133 million in retail revenues during the same year, but it only represents an overall share of only 5% of total satellite M2M/IoT revenues. ARPUs will be low on smallsat IoT networks"

"To turn a profit on these small satellite constellations purely from IoT, millions of IoT devices will be required. On each constellation. With only several million connected devices to come online on smallsats over the coming decade, competition will be extremely fierce between the 15+ constellations for this purpose, with most either merging or never actually launching."

"Further, satellite renewals must be considered, as the average life span for these satellites is up to 3 years. Any launch failure would significantly impact latency and IoT performance. Nonetheless, NSR expects a few smallsat IoT constellations to reach positive ROIs within the next 10 years, assuming additional financing is available to maintain positive cash flow over the first few years of launch."

"Low data rates (a few bytes) per packet transferred are fine for now; however, this fails to consider the growth of data requirements coming from big data analysis. This results in additional levels of data that will be transmitted, despite more analysis being done at the ‘edge’ and not transmitted via satellite. This is where ‘bigsat’ constellations such as Iridium NEXT and Globalstar’s second generation network come into play."

Bottom line: "the ROI on comparatively low-cost CAPEX of smallsats is depressed by even lower ARPUs and end-user demand."

FAA clears DJI and other drone companies to fly near airports - Engadget Oct 2018
The Federal Aviation Administration (FAA) has given nine companies permission to fly in controlled airspace, such as airports, as part of its Low Altitude Authorization and Notification Capability (LAANC) initiative. One of those nine companies is DJI, along with Aeronyde, Airbus, AiRXOS, Altitude Angel, Converge, KittyHawk, UASidekick and Unifly. It doesn't mean operators can fly those brands' drones over airports anytime they want, though -- it only means that professional drone pilots can now get authorization to enter controlled airspace in near-real time instead of waiting for months.

A pilot that's going to use a drone to conduct an inspection, capture photos and videos or herd birds away from airports, for instance, can now send their applications to fly in controlled airspace to LAANC

Experts see 5G as defense to 'Stingray' spying | TheHill
"Security experts and privacy advocates are hopeful the rollout of the new 5G wireless network could eliminate a glaring surveillance vulnerability that allows spying on nearby phone calls."

"Stingrays exploit cell towers that are the backbone of the current 4G network. ... 5G networks would be less reliant on those towers and also would require new security standards for communications. The new network would be built using smaller cells, which are about the size of refrigerators and located every few blocks."

"Lucca Hirschi and Ralf Sasse, two authors of a recent paper on 5G surveillance risks, told The Hill that their analysis of new standards for 5G found that the guidelines will limit the impact of existing stingrays. ... But the fix won't not cover all stingrays, Hirschi and Sasse told The Hill in an interview. The standards would block so-called passive devices, which just pick up communications, but different kinds of active tracking devices, which can force phones to disconnect from their networks, could still get through in 5G."

"That slow rollout means that for a period of time, multiple networks may be active at once. And that means devices built for 5G may have to connect to earlier networks like 4G, exposing those devices to vulnerabilities they weren’t designed to combat, experts told The Hill."

Deepfake Videos Are Getting Impossibly Good
"The new system was developed by Michael Zollhöfer, a visiting assistant professor at Stanford University, and his colleagues at Technical University of Munich, the University of Bath, Technicolor, and other institutions. Zollhöfer’s new approach uses input video to create photorealistic re-animations of portrait videos. These input videos are created by a source actor, the data from which is used to manipulate the portrait video of a target actor. So for example, anyone can serve as the source actor and have their facial expressions transferred to video of, say, Barack Obama or Vladimir Putin."

Reading in the era of digitisation: An introduction to the special issue | Kovač | First Monday Sep 2018
"Digital materials can be adapted to each individual’s skill level, enabling flexible learning processes to accommodate the particular needs and developments of each reader. At the same time, empirical research indicates that the affordances of screens may also foster less advantageous reading developments, habits and mind sets.

"This warrants balancing the discourse on possibilities and advantages of digital technologies. To this purpose ‘Evolution of Reading in the Age of Digitisation’ (E-READ) — a research initiative funded by COST (European Cooperation in Science & Technology) as Action IS1404 — has brought together almost 200 scholars and scientists of reading, publishing, and literacy from across Europe. Starting from the assumption that the introduction of digital technologies for reading is not neutral regarding cognition and comprehension, the members of the network joined in an effort to research how readers, and particularly children and young adults, comprehend or remember written text when using print versus digital materials.

"The main findings can be summarised in the following manner:

General comprehension when reading long-form text on a digital screen tends to be either about the same as or inferior to doing the same reading in print;

More demanding tasks (e.g., requiring greater depth of understanding or reproduction of detail or when longer texts are used) suffer more than leisure tasks (e.g., narrative reading);

Readers are more likely to be overconfident about their comprehension abilities when reading digitally than when reading print, in particular under time pressure;

Contrary to expectations about the behaviour of ‘digital natives’, screen inferiority effects have been increasing rather than decreasing over time, regardless of the age group and regardless of prior experience with digital environments;

Digital text offers unsurpassed opportunities to tailor text presentation to an individual’s needs, which has been found to support struggling readers to develop adequate reading skills;

Equivalence between the paper and screen mediums — and even an advantage of digital environments — can be achieved, provided conscious engagement in in-depth processing (e.g., writing keywords that summarize the text) is actively promoted.

How Facebook Was Hacked And Why It's A Disaster For Internet Security, Forbes Sep 2018
What’s most worrying of all, though, is what the hack has proven: that a company with the resources and power of Facebook can be robbed of keys that allow access to millions of accounts across the web. Given the keys allowed the hacker to take over any account using a Facebook login, the real number of affected individuals is likely far higher than 50 million.

Is 5G a Spectrum-eating Monster that Destroys Competition? Fred Goldstein, June 2018
"But 5G isn’t, as the FCC members tweet, a race that the US has to somehow “win” against China, lest uncertain horrors result. The likely real purpose of 5G is less obvious than its technology. 5G is more like a cult, a sacrificial cult that is being designed to kill off what little competition is left in the telecom industry."

"Today the biggest carriers and their backers have a new sun god called 5G. But unlike the sun, we don't know who really needs it. It’s based on a supplier-driven model, not a demand pull, given that 4G LTE has been both a technical and market success, and continues to be enhanced."

Uncannily real: volumetric video changes everything | New Scientist Dec 2017
Wonderful essay by Simon Ings - neat twist in the tail, I love the open to close:

"<open> OUTSIDE Dimension Studios in Wimbledon, south London, is one of those tiny wood-framed snack bars that served commercial travellers in the days before motorways. The hut is guarded by old shop dummies dressed in fishnet tights and pirate hats. If the UK made its own dilapidated version of Westworld, the cyborg rebellion would surely begin here.
<close> Jelley walks me back to the main road. Neither of us says a word. He knows what he has. He knows what he has done. Outside the snack shack, three shop dummies in pirate gear wobble in the wind."

"Truly immersive media will be achieved not through magic bullets, but through thugging – the application of ever more computer power, and the ever-faster processing of more and more data points. Impressive, but where’s the breakthrough?"

"The cameras shoot between 30 and 60 times a second. “We have a directional map of the configuration of those cameras, and we overlay that with a depth map that we’ve captured from the IR cameras. Then we can do all the pixel interpolation.” This is a big step up from mocap. Volumetric video captures real-time depth information from surfaces themselves: there are no fluorescent sticky dots or sliced-through ping-pong balls attached to actors here."
