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.
T-Mobile Chief Technology Officer Neville Ray wrote in a blog post that millimeter-wave spectrum used for 5G “will never materially scale beyond small pockets of 5G hotspots in dense urban environments.”
With 4G, carriers prioritized so-called “beachfront spectrum” below 1GHz in order to cover the entire US, both rural areas and cities.
5G networks will use both low and high frequencies, but they’re supposed to offer their highest speeds on millimeter waves.
Anyone in here teach instructional design that can recommend a textbook that teaches ADDIE or SAM but is inclusive and has an emphasis on instruction being culturally responsive or culturally sustaining?
The ADDIE model of instructional design is probably the most well-known approach for crafting learning solutions. ADDIE stands for Analyze, Design, Development, Implement, and Evaluate. But ADDIE isn’t the only game in town these days. One popular alternative to ADDIE is SAM, which stands for Successive Approximation Model.
Created by Allen Interactions, SAM offers an instructional design approach consisting of repeated small steps, or iterations, that are intended to address some of the most common instructional design pain points, like meeting timelines, staying on budget, and collaborating with Subject Matter Experts
Hi everyone- my mom has been teaching Bio 101 with a lab for 39 years. I’m working with her to get ready for the fall semester online but Science isn’t my field. Any recommendations for online bio labs?
Stephanie EdelmannI’m still working on my lab, but here is an extensive list of online resources that was shared with faculty at our school.
For introducing basic chemistry I really like the “Build an Atom” simulation on the PhET website, although it’s more of an activity than a “lab”. HHMI biointeractive has lots of free resources and data sets that you could build on, including lots for natural selection — try searching “rock pocket mouse natural selection” on the biointeractive website.
– Open YouTube
– Type / Voice Command: e.g. Smithsonian 360 or British Museum 360 or Ufizzi 360 and choose 360 video files suitable for the content of your course.
– e.g., Smithsonian has an excellent 360 degree tour of the Space Shuttle + narrative about the deployment of the Hubble Telescope: https://youtu.be/o3XS_5L–Qg, which can be an excellent intro to Astronomy class
– e.g., Smithsonian offers a 360 degree tour of the Museum of American History: https://youtu.be/TkUPzRB7p5g
– e.g., Ufizzi Gallery, British Museum present 360 degree tours of artifacts for Ancient History, Art, History of Art: https://youtu.be/SPeW0YWLVvE

Assignment: Group work
Find one F2F and one online peer to form a group.
Based on the questions/directions before you started watching the videos:
– Does this particular technology fit in the instructional design (ID) frames and theories covered
– how does this particular technology fit in the instructional design (ID) frames and theories covered so far?
– what models and ideas from the videos you will see seem possible to be replicated by you?
