A man who has been an AT&T customer since 1960 has a message for CEO John Stankey about the company's failure to upgrade DSL areas to modern Internet service. Aaron Epstein, 90, is so frustrated by his 3Mbps Internet plan that he took out a Wall Street Journal ad in today's print edition in order to post an open letter to Stankey. From a report: "Dear Mr. Stankey: AT&T prides itself as a leader in electronic communications. Unfortunately, for the people who live in N. Hollywood, CA 91607, AT&T is now a major disappointment," Epstein wrote in the letter. Epstein paid $1,100 to run the ad for one day in the Manhattan and Dallas editions of today's Journal, he told Ars in a phone interview. He chose the Manhattan edition to reach investors who might want to pressure AT&T into upgrading its network and Dallas because that's where AT&T is headquartered, he said. "We need to keep up with current technology and have looked to AT&T to supply us with fast Internet service," Epstein wrote in the open letter to AT&T's CEO. "Yet, although AT&T is advertising speeds up to 100Mbps for other neighborhoods, the fastest now available to us from AT&T is only 3Mbps. Your competitors now have speeds of over 200Mbps. Why is AT&T, a leading communications company, treating us so shabbily in North Hollywood?"

Tesla boss Elon Musk said in an interview late Sunday that a monkey has been wired up to play video games with its mind by a company he founded called Neuralink. CNBC reports: Neuralink put a computer chip into the monkey's skull and used "tiny wires" to connect it to its brain, Musk said. "It's not an unhappy monkey," he said during a talk on Clubhouse, a new social media app gaining popularity that allows people to have informal voice chats while others listen in. "You can't even see where the neural implant was put in, except that he's got a slight like dark mohawk."

The billionaire -- who also spoke about space travel, colonies on Mars, crypto, artificial intelligence and Covid-19 vaccines -- said Neuralink is trying to figure out if it can use its chips to get monkeys to play "mind Pong" with each other. "That would be pretty cool," said Musk, who is CEO of Neuralink, in addition to SpaceX and Tesla. Neuralink's team of around 100 people is trying to develop an implementable computer-brain interface. Musk describes it as a Fitbit in your skull with tiny wires that go into your brain. [...] Musk said Neuralink will "probably" be releasing some videos that show the company's progress in the next month or so. Last August, Neuralink conducted a live demo of its technology on three pigs. A wireless link from the Neuralink device showed the pig's activity activity as it snuffled around a pen on stage.

Musk made the comments on the audio chat app Clubhouse, where he also grilled Robinhood CEO about what happened with GameStop.

Xiaomi, the world's third largest smartphone maker, today unveiled "Mi Air Charge Technology" that it says can deliver 5W power to multiple devices "within a radius of several metres" as the Chinese giant invited customers to a "true wireless charging era." From a report: The company said it has self-developed an isolated charging pile that has five phase interference antennas built-in, which can "accurately detect the location of the smartphone." A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming, the company said, adding that âoein the near futureâ the system will also be able to work with smart watches, bracelets, and other wearable devices. A company spokesperson said Xiaomi, which has previously introduced 80W and 120W wireless charging tech, won't be deploying this new system to consumer products this year.

During its fourth-quarter earnings announcement, Tesla unveiled the long-rumored refresh for its Model S sedan. CNET reports: On the outside, the Model S has a new front bumper with slightly different intakes, a tweaked rear diffuser and new 19- and 21-inch wheel designs. All of the exterior trim is now finished in black to match the Model Y, but the paint color palette remains the same, with white being the only no-cost option. The interior is the star of the show, though. It's been completely redesigned, marking the Model S' first major update since its debut in 2012. There's a large 17-inch central screen much like that of the Model 3 and Model Y, but the S retains a 12.3-inch digital gauge cluster in front of the driver, as well. Tesla says the new center screen is basically a gaming computer with 10 teraflops of processing power, and the released images show it running the popular fantasy RPG game Witcher 3.

Most radical is the new steering wheel. It isn't exactly a wheel anymore, instead looking like a yoke right out of Star Wars or Knight Rider. There are no stalks, either, meaning the turn signals, lights and other typical features are now controlled by touch buttons on the "wheel." There's more carbon fiber or wood trim covering parts of the dashboard and door panels, and the door cards and center console have been redesigned for more storage space and better looks. The rear seats look more sculpted and have a new fold-down armrest with cupholders. Rear-seat passengers get an 8-inch screen that offers the same infotainment and gaming functions as the main screen, and it even works with wireless gaming controllers. The Model S has three-zone climate control, a 22-speaker audio system, heated seats all around (and ventilated front seats), ambient lighting and a glass roof as standard. White, black and beige remain the only interior color options. The maxed-out "Plaid Plus" model, which comes in at $139,990, features over 1,100 hp and will hit 60 mph in under 2 seconds. "It also boats a sub-9-second quarter-mile time, a top speed of 200 mph and a range of over 520 miles," reports CNET.

According to analyst Ming-Chi Kuo, Apple's upcoming iPhone 13 could feature vapor chamber cooling, as well as an in-screen fingerprint sensor. It may also completely ditch the Lightning port in favor of wireless charging. Apple Insider reports: Kuo believes Apple is highly likely to incorporate vapor chamber tech into an upcoming iPhone model, though it is not clear if the system will be ready in time for 2021. Generally speaking, vapor chamber (VC) technology involves evaporation of a liquid (typically water) within a specialized heat pipe or heat retention structure that snakes its way through a device chassis. Heat from processors and other high load electronic components causes the liquid to evaporate into a vapor that spreads thermal energy through the evaporation chamber as it travels to areas of lower pressure. Fins or other condenser bodies remove heat from the vapor, which returns to a liquid state and is carried back to areas of high pressure through capillary action.

"The iPhone's critical reason not to adopt VC is because of its reliability test results that cannot meet Apple's high requirements," Kuo writes. "Still, we are optimistic about the VC reliability improvement schedule and expect that at least high-end iPhone models would be equipped with VC in the near future." Kuo believes iPhone will need VC to keep up with rapid adoption of 5G and ever-increasing CPU thermal loads. In a separate report, Bloomberg reports that Apple is testing another key feature for its 2021 iPhone(s): an in-screen fingerprint reader. "This would add a new method for users to unlock their iPhone, going beyond a passcode and Face ID facial recognition," reports Bloomberg. "Apple won't remove its facial recognition scanner though as it's still useful for augmented reality and camera features."

The report also mentions that Apple is discussing removing the Lightning port on at least some of the 2021 iPhone models, instead relying entirely on wireless charging or USB-C.

D-Link is trying to make it simple to give your computer a Wi-Fi upgrade. From a report: The networking company has announced what it's calling an "industry-first" Wi-Fi 6 adapter built into a USB stick. Plug it into your laptop or desktop computer, and you may be able to get better performance than from your older Wi-Fi chip. The adapter advertises speeds up to 1,200Mbps. It's not entirely clear who the target audience is for this upgrade. You'll need to be connected to a Wi-Fi 6 router to get the biggest benefits, and most people still don't own one of those (the Wi-Fi 6 standard only started rolling out two years ago). And if the laptop or desktop you're using was bought any time in recent memory, chances are it supports Wi-Fi 5, which isn't a huge step down from Wi-Fi 6.

"Both local police and the FBI are seeking information about individuals who were 'actively instigating violence' in Washington, DC, on January 6," writes Ars Technica.

Then they speculate on which tools will be used to find them: While media organizations took thousands of photos police can use, they also have more advanced technologies at their disposal to identify participants, following what several other agencies have done in recent months... In November, The Washington Post reported that investigators from 14 local and federal agencies in the DC area have used a powerful facial recognition system more than 12,000 times since 2019.

Neither would an agency need actual photos or footage to track down any mob participant who was carrying a mobile phone. Law enforcement agencies have also developed a habit in recent years of using so-called geofence warrants to compel companies such as Google to provide lists of all mobile devices that appeared within a certain geographic area during a given time frame...

With all of that said, however, the DC Metropolitan Police and the FBI will probably need to look no further than a cursory Google search to identify many of the leaders of Wednesday's insurrection, as many of them took to social media both before and after the event to brag about it in detail. In short: you don't need fancy facial recognition tools to identify people who livestream their crimes.
Friday the Washington Post also cited "the countless hours of video — much of it taken by the rioters themselves and uploaded to social media" as a useful input for facial recognition software.

But in addition, they note that "The Capitol, more than most buildings, has a vast cellular and wireless data infrastructure of its own to make communications efficient in a building made largely of stone and that extends deep underground and has pockets of shielded areas. Such infrastructure, such as individual cell towers, can turn any connected phone into its own tracking device.

"Phone records make determining the owners of these devices trivially easy..."

Wi-Fi is about to get a lot better. Many of this year's new phones, laptops, TVs, routers, and more will come with support for Wi-Fi 6E, a new upgrade to Wi-Fi that's essentially like expanding your wireless connection from a two-lane road to an eight-lane highway. From a report: It's the biggest upgrade to Wi-Fi in 20 years, and connections should be faster and a lot more reliable because of it. The Wi-Fi Alliance, the industry-wide group that oversees Wi-Fi, is now starting to certify the first wave of products with support for Wi-Fi 6E. Phones, PCs, and laptops with support should start hitting the market in the first months of 2021, according to the IDC research group, and TVs and VR devices with support are expected to arrive by the middle of the year. Some of the first devices are likely to be announced over the next week.

Verizon has backtracked on its plan to turn off its 3G network by the end of 2020. Light Reading reports: In response to questions from Light Reading, Verizon spokesperson Kevin King said "our 3G network is operational and we don't have a plan to shut it down at this time. We'll work with customers to move them to newer technology." That's a decided change from Verizon's plans from roughly a year ago. In July 2019, Verizon spokesperson Howie Waterman confirmed to Light Reading that the operator had delayed the shuttering of its 3G network from the end of 2019 to the end of 2020. He said the action would give impacted customers "an extra year to decide what they want to do." Verizon's decision to keep its 3G network up and running means the service provider will continue to operate three separate wireless network technologies -- 3G, 4G and 5G -- for the foreseeable future. As for the other carriers, AT&T plans to shutter its own 3G network in "early" 2022 and T-Mobile has said it will shut down its 3G network "over the next several years" but "we haven't shared timing."

An anonymous reader shares a report: Malware operators who want to know the location of the victims they infect usually rely on a simple technique where they grab the victim's IP address and check it against an IP-to-geo database like MaxMind's GeoIP to get a victim's approximate geographical location. While the technique isn't very accurate, it is still the most reliable method of determining a user's actual physical location based on data found on their computer. However, in a blog post last month, Xavier Mertens, a security researcher with the SANS Internet Storm Center, said he discovered a new malware strain that is using a second technique on top of the first. This second technique relies on grabbing the infected user's BSSID. Known as a "Basic Service Set Identifier," the BSSID is basically the MAC physical address of the wireless router or access point the user is using to connect via WiFi. You can see the BSSID on Windows systems by running the command: netsh wlan show interfaces | find "BSSID" Mertens said the malware he discovered was collecting the BSSID and then checking it against a free BSSID-to-geo database maintained by Alexander Mylnikov.

The Federal Communications Commission's ongoing sale of wireless licenses has fetched more than $66.4 billion after three weeks of bidding, a record sum that could alter cellphone carriers' prospects for the next decade. From a report: The auction proceeds have already topped the $44.9 billion raised in 2015 by an earlier sale of midrange cellular licenses, which U.S. cellphone carriers used at the time to enhance their 4G service. Those companies are now investing billions of dollars in the next wave of fifth-generation coverage. The 5G standard promises to speed the flow of data to phones and other wireless devices like personal computers, cars and industrial machinery. The recent bids have blown past Wall Street's highest forecasts, suggesting that several companies are fighting over the most valuable wireless rights. The 5G auction kicked off Dec. 8 and will pause for the holidays until Jan. 4, when total bids could move even higher. Each bid is swathed in secrecy until the auction process ends. Analysts expect big names like AT&T and Verizon Communications to walk away with a large share of the licenses to match assets that rival T-Mobile captured with its February takeover of Sprint.

Nigeria's telecommunications regulator ordered mobile-phone users to link their devices to their national identity numbers, raising the prospect of millions of lines being blocked. From a report: Subscribers have until Dec. 31 to comply with the requirement, the Nigerian Communications Commission said in a statement Tuesday on its website. Failure to do so will result in their phone lines being cut off in January, it said. Africa's largest economy had about 196 million active phone lines as of June 2020, NCC data shows. At the same time, only 41.5 million Nigerians had the required identity numbers, according to information on the website of the National Identity Management Commission, which is in charge of registrations. MTN Group's local unit is the biggest wireless operator in the West African country. Airtel Africa, which listed in Lagos and London last year, vies with local operator Globacom to be the country's second-biggest carrier.

Academics from an Israeli university have published new research today detailing a technique to convert a RAM card into an impromptu wireless emitter and transmit sensitive data from inside a non-networked air-gapped computer that has no Wi-Fi card. From a report: Named AIR-FI, the technique is the work of Mordechai Guri, the head of R&D at the Ben-Gurion University of the Negev, in Israel. Over the last half-decade, Guri has led tens of research projects that investigated stealing data through unconventional methods from air-gapped systems. [...] At the core of the AIR-FI technique is the fact that any electronic component generates electromagnetic waves as electric current passes through. Since Wi-Fi signals are radio waves and radio is basically electromagnetic waves, Guri argues that malicious code planted on an air-gapped system by attackers could manipulate the electrical current inside the RAM card in order to generate electromagnetic waves with the frequency consistent with the normal Wi-Fi signal spectrum (2,400 GHz). In his research paper, titled "AIR-FI: Generating Covert WiFi Signals from Air-Gapped Computers," Guri shows that perfectly timed read-write operations to a computer's RAM card can make the card's memory bus emit electromagnetic waves consistent with a weak Wi-Fi signal. This signal can then be picked up by anything with a Wi-Fi antenna in the proximity of an air-gapped system, such as smartphones, laptops, IoT devices, smartwatches, and more. Guri says he tested the technique with different air-gapped computer rigs where the Wi-Fi card was removed and was able to leak data at speeds of up to 100 b/s to devices up to several meters away.

T-Mobile last week introduced the market's newest 5G moniker: "Ultra Capacity." The label, writes blog LightReading, will stew alongside "5G Ultra Wideband," "Extended Range 5G," "5G+," "5Ge," "5GTF," "5G Nationwide" and plain-old "5G" in the US wireless industry, ensuring that if American mobile customers aren't confused yet, it's only a matter of time before they're hopelessly bewildered by operators' thesaurus-toting marketing executives. So here's that 5G lexicon everyone is apparently going to need, the blog reports:
5G Ultra Capacity: This is the new brand that T-Mobile is applying to its 5G network running in the midband 2.5GHz spectrum it acquired from Sprint, as well as its highband, millimeter wave (mmWave) spectrum. The operator said customers with "5G Ultra Capacity" phones and coverage can expect speeds around 300 Mbit/s up to peaks of 1 Gbit/s.
5G Ultra Wideband: This is the label Verizon has applied to its 5G network running in its own mmWave spectrum. Due to the physics of signal propagation in such spectrum, mmWave transmitters can't reach receivers that are more than a few thousand feet away.
5G+: This is the label AT&T has applied to its own mmWave network. However, the operator appears to be focusing its energies on 5G in other spectrum bands.
Extended Range 5G: This is the label T-Mobile has given to its 5G network in its lowband 600MHz spectrum, which supports slower speeds than mmWave or midband networks. As you can imagine, given the name, signals in Extended Range 5G go much, much further than signals in mmWave spectrum, again due to the physics of signal propagation in lowband spectrum like 600MHz. Verizon and AT&T also operate extensive lowband 5G networks.
5G Nationwide: This is the label Verizon has applied to its lowband 5G network. It's similar to T-Mobile's "Extended Range 5G," although T-Mobile has dedicated some 600MHz spectrum to 5G while Verizon is using a technology called Dynamic Spectrum Sharing (DSS) to put both 4G and 5G signals in its lowband spectrum.
5Ge: This is the moniker AT&T gave to its 4G LTE network in 2018, sparking plenty of controversy. The action allowed AT&T to quickly offer 5G icons to most of its customers without actually having to deploy a 5G network that adheres to the 3GPP's official 5G technology standard.
5GTF: This is the technology label that Verizon tacitly applied to its initial 5G Home fixed wireless service running in its mmWave spectrum. The network initially did not work on the official 3GPP 5G technology standard and instead worked on a derivation developed by Verizon and its vendors. However, Verizon has since shifted its 5G Home service to the official 3GPP 5G standard.
5G: This is the catch-all label that operators are applying to whatever their marketing teams haven't gotten their fingers on yet. T-Mobile used "5G" for a while until it introduced "Ultra Capacity," and AT&T still uses "5G" for its lowband 5G network.

Norman Abramson, one of the pioneers behind wireless networks, has died at 88. The cause was skin cancer that had metastasized to his lungs, his son, Mark, said. The New York Times reports: Professor Abramson's project at the University of Hawaii was originally designed to transmit data to schools on the far-flung Hawaiian islands by means of a radio channel. But the solution he and his group devised in the late 1960s and early '70s would prove widely applicable; some of their technology is still in use in today's smartphones, satellites and home WiFi networks. The technology they created allowed many digital devices to send and receive data over that shared radio channel. It was a simple approach that did not require complex scheduling of when each packet of data would be sent. If a data packet was not received, it was simply sent again. The approach was a departure from telecommunications practices at the time, but it worked.

The wireless network in Hawaii, which began operating in 1971, was called ALOHAnet, embracing the Hawaiian salutation for greeting or parting. It was a smaller, wireless version of the better known ARPAnet, the precursor to the internet, which allowed researchers at universities to share a network and send messages over landlines. The ARPAnet was led by the Pentagon's Advanced Research Projects Agency, which also funded the ALOHAnet. "The early wireless work in Hawaii is vastly underappreciated," said Marc Weber, an internet historian at the Computer History Museum in Mountain View, Calif. "Every modern form of wireless data networking, from WiFi to your cellphone, goes back to the ALOHAnet."

An anonymous reader shares a report: More than one billion people in India today have a mobile connection, thanks in part to the proliferation of low-cost Android smartphones and the world's cheapest mobile data plans in recent years. This scale was unimaginable just three decades ago, when India had fewer than 2.5 million telephones in the country. One of the earliest and most pivotal efforts that expanded the reach of telephones in the country took place in the late 1980s. That was when the Indian government backed the idea of setting up telephone booths, or public call offices, across cities and towns. No longer did people need to buy expensive telephones, or pay exorbitant fees and bills. A person could just walk to a nearby mom and pop store, place a call for a couple of cents and move on.

On Wednesday, India's cabinet approved a proposal that seeks to replicate the decades-old strategy -- and its success -- with democratizing Wi-Fi in the world's second-largest internet market. India's IT Minister Ravi Shankar Prasad said that the government will launch PM WANI (Prime Minister Wi-Fi Access Network Interface) to "unleash a massive network in the country." The neighborhood stores that served as public call offices could now be public data offices, he said. To make the program a success, the government will not charge any license or registration fee, he said.

Chrome OS 87 starting rolling out on Thursday, adding the ability to search tabs, view the battery levels of your Bluetooth devices, and more. 9to5Google reports: Tab Groups help people better manage (and collapse/hide) tabs, but it doesn't always reduce the number open. Google is now introducing Tab Search to let users find what pages they have open across all windows. Tapping the circular dropdown button in the top-right corner -- also accessible with Ctrl+Shift+A -- first shows a list of everything open. It includes the favicon, page name, and domain, as well as an individual close button. This feature is first rolling out to Chromebooks before coming to desktop browsers.

Chrome OS 87 will list the Bluetooth battery levels of accessories in Settings and Quick Settings. Just navigate to the Bluetooth menu. This feature is primarily meant for wireless headphones and will show a notification with the current level in the bottom-right corner of your screen upon connection. Chrome OS 87 also adds 36 new backgrounds created by four different artists. To set, right-click on the desktop or shelf and select "Set wallpaper."

Other features in this release include:
- Saving to Google Drive has been updated with the ability to rename the file and selecting what folder to store it in
- Chrome OS devices now support switch accessibility devices
- Google has updated language settings to be easier for multilingual users to navigate
- The Alt+Tab window switcher now supports mouse, touch screen, and stylus input
- Version 87 makes visual improvements when renaming Virtual Desks and Launcher folders

Discovery is the latest media company to jump into the ever more crowded streaming wars. It will launch its streaming service Discovery+ on Jan. 4, 2021. The service will include a $4.99 per month ad-supported tier and a $6.99 per month ad-free tier. From a report: The lower $4.99 tier costs the same as NBCUniversal-owned Peacock's premium tier with ads. The ad-free $6.99 tier is on par with what Disney+ costs. Both offerings are much less expensive than WarnerMedia's HBO Max, which costs $14.99 a month, and Netflix, which raised its standard plan to $13.99 a month in Oct. Discovery is also partnering with Verizon, which will give 55 million customers up to 12 months of the ad-free Discovery+ plan for free, depending on their wireless plan with the carrier.

Britain will spend $333 million to diversify its sources of 5G wireless equipment after banning China's Huawei from supplying the next-generation technology. From a report: Huawei is set to be excluded from British 5G networks by 2027 due to security concerns, leaving phone carriers reliant on a supply duopoly of Finland's Nokia and Sweden's Ericsson. Around $67 million of the total will be spent next year to help build "a secure and resilient 5G network" according to documents published on Wednesday as part of Chancellor of the Exchequer Rishi Sunak's spending review. The resulting reduction in competition could hurt security and push up prices, so Digital Secretary Oliver Dowden has started a task force to increase the number of suppliers. He is set to publish more details before the end of the year.

Britain's crackdown on Huawei came in July after UK officials said US sanctions made it impossible to verify the security of Huawei's supply chain. The White House accuses Huawei of being a security risk, which the company has always denied. Since then, Nokia and Ericsson have already won major contracts from British carriers like BT Group and CK Hutchison Holdings' Three UK. The phone industry is banking that longer-term initiatives such as OpenRAN -- a project to make mobile network equipment more interoperable and encourage new suppliers -- will eventually introduce more competition.

The U.K.-based security company NCC Group and consumer advocacy group Which? have found vulnerabilities in 11 "smart" doorbells sold on popular platforms like Amazon and eBay. CyberScoop reports: One flaw could allow a remote attacker to break into the wireless network by swiping login credentials. Another critical bug, which has been around for years, could enable attackers to intercept and manipulate data on the network. The investigation focused on doorbells made by often obscure vendors, but which nonetheless earned top reviews and featured prominently on Amazon and eBay. The researchers raised concerns that some of the devices were storing sensitive data, including location data and audio and video captured by the doorbell's camera, on insecure servers. One device made by a company called Victure, for example, sent a user's wireless name and password, unencrypted, to servers in China, according to the researchers.

In a statement, Amazon said it requires products sold on its site to be compliant with applicable laws and regulations, and that it has tools to detect "unsafe or non-compliant products from being listed in our stores." eBay said it takes down listings that violate its safety standards, but that the devices flagged by the researchers did not meet that threshold. Victure did not immediately respond to a request for comment. The NCC Group-Which? team said they tried to contact the various vendors of the vulnerable smart doorbells, with mixed success. The unnamed vendor of one device, for example, removed an online listing for the product after the researchers shared their findings.
