analytical skills COVID 5G

The research, published in the journal Royal Society Open Science
Researchers at Cambridge University said the findings suggested improving people’s analytical skills could help turn the tide against an epidemic of “fake news” surrounding the health crisis.

Some scientists think that susceptibility to misinformation is related to political views, while others think it is linked to reasoning abilities.
Another distinct factor linked to belief in Covid-19 “fake news” was age, the researchers found. Being older was associated with lower susceptibility to misinformation everywhere (except Mexico)

Political conservatism was also linked to a slightly higher susceptibility to misinformation, the researchers found, but surprisingly, this link was not as strong in the US and UK as it was elsewhere.

Hands-on is “goggles-on”

https://www.insidehighered.com/digital-learning/blogs/online-trending-now/hands-classes-distance-and-emerging-virtual-future

As we enter the Fourth Industrial Revolution (4IR), we must be vigilant to keep our classes relevant to the rapidly changing workplace and the emerging digital aspects of life in the 2020s.

deployment of 5G delivery to mobile computing

Certainly, 5G provides a huge upgrade in bandwidth, enabling better streaming of video and gaming. However, it is the low latency of 5G that enables the most powerful potential for distance learning. VR, AR and XR could not smoothly function in the 4G environment because of the lag in images and responses caused by a latency rate of 50 milliseconds (ms). The new 5G technologies drop that latency rate to 5 ms or less, which produces responses and images that our brains perceive as seamlessly instant.

Top 10 Strategic Technologies

    1. Uses of APIs
    2. Institutional support for accessibility technologies
    3. Blended data center (on premises and cloud based)
    4. Incorporation of mobile devices in teaching and learning
    5. Open educational resources

Technologies for improving analysis of student data

    1. Security analytics
    2. Integrated student success planning and advising systems
    3. Mobile apps for enterprise applications
    4. Predictive analytics for student success (institutional level)

At least 35% of institutions are tracking these five technologies in 2020: Support for 5G; Wi-Fi 6 (802.11 ax, AX Wi-Fi); Identity as a Service (IDaaS); Digital microcredentials (including badging); Uses of the Internet of Things for teaching and learning; and Next-generation digital learning environment

Broadband China US

China’s Fiber Broadband Internet Approaches Nationwide Coverage; United States Lags Severely Behind from r/technology

China’s Fiber Broadband Internet Approaches Nationwide Coverage; United States Lags Severely Behind 

In 2013, 17 percent of consumers in both China and the U.S. had access to a fiber internet connection. Fast forward to 2019, China’s penetration has jumped to 86 percent while the U.S. is only at 25 percent.

Despite the constant posturing and discussion about the importance of fiber, the U.S. has not been effective at deploying a nationwide fiber optical network. Why is this?

LACK OF PRIVATE COMPETITION

INADEQUATE BROADBAND MAPPING

INEFFICIENT NATIONAL FUNDING PROGRAMS

ABSENCE OF COMMON SENSE STATE-LEVEL INFRASTRUCTURE POLICIES

Unlike America, virtually all of the access points that make up the internet “backbone” in China are state-owned, with private providers only able to lease out bandwidth from the government. The communist government’s plans extend beyond its own borders as well; the Belt and Road Initiative includes plans for direct investment in infrastructure spanning nearly 70 different countries, potentially giving China a vice grip on internet innovation if left unchecked by the West.

5G vs WiFi6

https://www.cnet.com/news/wi-fi-6-will-upgrade-your-workhorse-wireless-network/

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.

5G and urban areas

Millimeter-wave 5G will never scale beyond dense urban areas, T-Mobile says

T-Mobile CTO says 5G’s high-frequency spectrum won’t cover rural America.
