Wi-Fi 6, the consumer-friendly new name for the tech standard actually called 802.11ax,
wireless chip designer Qualcomm is betting big on Wi-Fi 6
“Cord cutting is real. What was typically one TV in the average home is now five or six different screens,” Patel said. “There’s a tremendous amount of content sourced through the home that wasn’t before. There’s a congestion problem.”
One of Wi-Fi 6’s biggest advances is OFDMA — orthogonal frequency division multiple access, if you must know — an efficiency-boosting technology purloined from mobile networks. Another is MU MIMO, short for multiple user, multiple input, multiple output. And then there’s 1024 QAM — quadrature amplitude modulation — which bumps up data rates by 30%.
- Double the range — though Qualcomm has built-in mesh networking technology that’ll let multiple wireless access points cooperate to bathe your house in Wi-Fi radio signals.
- Triple the speed — useful not just for watching 4K video but also for uploading from our phones.
- Better reliability — good for avoiding video chats plagued by stuttering.
Qualcomm President Cristiano Amon says Wi-Fi 6 and 5G networks complement each other.

In 2019, does it matter where do we perform our work?
When I asked in 2009 to use e-conferencing tools (Skype, Adobe Connect back then) to allow better attendance at faculty meetings, there was a mountain of arguments why NOT to. Such attitude was clearly expressed during the slow and painful advent of “online” education, which still leans more to “correspondence course” mentality rather then synchronous and interactive modern education.
The worst part is that in 2019 the attitude still persists.
Online Learning’s ‘Greatest Hits’

Learning Management Systems
Neck and neck for the top spot in the LMS academic vendor race are Blackboard—the early entry and once-dominant player—and coming-up quickly from behind, the relatively new contender, Canvas, each serving about 6.5 million students . The LMS market today is valued at $9.2 billion.
Digital Authoring Systems
Faced with increasingly complex communication technologies—voice, video, multimedia, animation—university faculty, expert in their own disciplines, find themselves technically perplexed, largely unprepared to build digital courses.
instructional designers, long employed by industry, joined online academic teams, working closely with faculty to upload and integrate interactive and engaging content.
nstructional designers, as part of their skillset, turned to digital authoring systems, software introduced to stimulate engagement, encouraging virtual students to interface actively with digital materials, often by tapping at a keyboard or touching the screen as in a video game. Most authoring software also integrates assessment tools, testing learning outcomes.
With authoring software, instructional designers can steer online students through a mixtape of digital content—videos, graphs, weblinks, PDFs, drag-and-drop activities, PowerPoint slides, quizzes, survey tools and so on. Some of the systems also offer video editing, recording and screen downloading options
Adaptive Learning
As with a pinwheel set in motion, insights from many disciplines—artificial intelligence, cognitive science, linguistics, educational psychology and data analytics—have come together to form a relatively new field known as learning science, propelling advances in a new personalized practice—adaptive learning.
MOOCs
Of the top providers, Coursera, the Wall Street-financed company that grew out of the Stanford breakthrough, is the champion with 37 million learners, followed by edX, an MIT-Harvard joint venture, with 18 million. Launched in 2013, XuetangX, the Chinese platform in third place, claims 18 million.
Former Yale President Rick Levin, who served as Coursera’s CEO for a few years, speaking by phone last week, was optimistic about the role MOOCs will play in the digital economy. “The biggest surprise,” Levin argued, “is how strongly MOOCs have been accepted in the corporate world to up-skill employees, especially as the workforce is being transformed by job displacement. It’s the right time for MOOCs to play a major role.”
In virtual education, pedagogy, not technology, drives the metamorphosis from absence to presence, illusion into reality. Skilled online instruction that introduces peer-to-peer learning, virtual teamwork and other pedagogical innovations stimulate active learning. Online learning is not just another edtech product, but an innovative teaching practice. It’s a mistake to think of digital education merely as a device you switch on and off like a garage door.

OneNote
OneNote is the obvious choice for anyone who is using a Microsoft Surface or other Windows-based tablet. It is also available to use on iPads and on Android tablets. The option to have handwriting converted to text is an outstanding feature.
Google Keep
If you’re a G Suite for Education user, Google Keep. It doesn’t have the handwriting-to-text function that OneNote offers.
Zoho Notebook
Zoho Notebook doesn’t have the name recognition of OneNote or Keep. Zoho Notebook has the most intuitive design or organization options of the three digital notebooks featured here.
The downside to Zoho Notebook is that the handwriting option only appears on the Android and iOS platforms. If the handwriting option worked in the Chrome or Edge web browsers,

Ellis, D. A. (2019). Are smartphones really that bad? Improving the psychological measurement of technology related behaviors. Computers in Human Behavior, 97
, 60-66
Conclusions sur- rounding use have therefore been
largely negative and smartphones have repeatedly
been associated with depression (Elhai, Dvorak,
Levine, & Hall, 2017), anxiety (Richardson,
Hussain, & Griffiths, 2018), disrupted sleep
(Rosen, Carrier, Miller, Rokkum, & Ruiz, 2016),
cognitive
impairment (Clayton,
Leshner,&
Almond, 2015), and poor academic performance
(Lepp, Barkley, & Karpinski, 2015). This repeats a
pattern of research priorities, which previously
focused on the ne- gative impacts of many other
screen-based technologies, systematically moving
from television and video games, to the internet
and social media (Rosen et al., 2014).
There is also little
evidence to support the existence of the constructs
under investigation (e.g., technology ‘addiction’),
yet many papers and scales continue to use
language associated with a specific diagnosis (see
Panova & Carbonell, 2018 for a recent review).
When it comes to understanding the impact of
technology more generally, there is an intrinsic
lack of high-quality evidence (Ellis et al., 2018a).
Revised psychometric tests may hold some value
in the future, provided they are grounded in
relevant theory and validated accordingly.

Recent reports have noted how companies use data gathered from cell towers, ambient Wi-Fi, and GPS. But the location data industry has a much more precise, and unobtrusive, tool: Bluetooth beacons.
Most people aren’t aware they are being watched with beacons, but the “beacosystem” tracks millions of people every day. Beacons are placed at airports, malls, subways, buses, taxis, sporting arenas, gyms, hotels, hospitals, music festivals, cinemas and museums, and even on billboards.
Companies like Reveal Mobile collect data from software development kits inside hundreds of frequently used apps. In the United States, another company, inMarket, covers 38 percent of millennial moms and about one-quarter of all smartphones, and tracks 50 million people each month. Other players have similar reach.
A Software Development Kit is code that’s inserted into an app and enables certain features, like activating your phone’s Bluetooth sensor. Location data companies create S.D.K.s and developers insert them into their apps, creating a conduit for recording and storing your movement data.
Beacons are also being used for smart cities initiatives. The location company Gimbal provided beacons for LinkNYC kiosks that provoked privacy concerns about tracking passers-by. Beacon initiatives have been started in other cities, including Amsterdam (in partnership with Google), London and Norwich.
Familiar tech giants are also players in the beacosystem. In 2015, Facebook began shipping free Facebook Bluetooth beacons to businesses for location marketing inside the Facebook app. Leaked documents show that Facebook worried that users would “freak out” and spread “negative memes” about the program. The company recently removed the Facebook Bluetooth beacons section from their website.
Not to be left out, in 2017, Google introduced Project Beacon and began sending beacons to businesses for use with Google Ads services. Google uses the beacons to send the businesses’ visitors notificationsthat ask them to leave photos and reviews, among other features. And last year, investigators at Quartz found that Google Android can track you using Bluetooth beacons even when you turn Bluetooth off in your phone.
Companies collecting micro-location data defend the practice by arguing that users can opt out of location services. They maintain that consumers embrace targeted ads because they’re more relevant.
You can download an app like Beacon Scanner and scan for beacons when you enter a store. But even if you detect the beacons, you don’t know who is collecting the data.
