Passive Wi-Fi Uses 10,000 Times Less Power Than Standard; Likely to Replace Bluetooth

Feb 25, 2016 - 12:17 PM - by dgstorm

Engineers in the United States have made the final breakthrough for technology called Passive Wi-Fi. It's set to drive the revolution of the IoT (Internet of Things) and replace Bluetooth eventually. Passive Wi-Fi can generate an 11Mbps Wi-Fi connection, and although that doesn't seem very impressive, it does it with 10,000 times less power than standard Wi-Fi connections.

Additionally, the latest successful tests for Passive Wi-Fi had a range of 100 feet (30 meters) and consumed 1,000 times less energy, but with up to 11 times faster speeds than existing low energy standards, like Bluetooth and Zigbee.

Here's a quote with a few more details,

"To achieve such low-power Wi-Fi transmissions, the team essentially decoupled the digital and analog operations involved in radio transmissions.

The Passive Wi-Fi architecture assigns the analog, power-intensive functions - like producing a signal at a specific frequency - to a single device in the network that is plugged into the wall.

An array of sensors produces Wi-Fi packets of information using very little power by simply reflecting and absorbing that signal using a digital switch."

Joshua Smith, associate professor of computer science and engineering had this to say about the breakthrough, "Now that we can achieve Wi-Fi for tens of microwatts of power and can do much better than both Bluetooth and ZigBee, you could now imagine using Wi-Fi for everything."

It's amazing the magical things the wizards of engineering can create! Check out the video in the thread below for a demo of the new Passive Wi-Fi tech.

Facebook Finally Rolls Out Expanded 'Like' Button with 6 New 'Reactions'

Feb 24, 2016 - 10:47 AM - by dgstorm

It looks like Facebook finally finalized their new expanded "Like" button. They call the new extra like functions "Reactions," and there are 6 of them. These include the standard "Like" as well as Love, Haha, Wow, Sad and Angry. These will obviously give users a wider range and variation on how they respond to Facebook posts.

It certainly took them a while to nail these down, especially when you consider that forums across the web have had this functionality for years. One could argue that Facebook is simply one gigantic social forum, so why couldn't Facebook have expanded this system sooner? Here's what Facebook themselves had to say about that,

"We understand that this is a big change, and want to be thoughtful about rolling this out. For more than a year we have been conducting global research including focus groups and surveys to determine what types of reactions people would want to use most. We also looked at how people are already commenting on posts and the top stickers and emoticons as signals for the types of reactions people are already using to determine which reactions to offer."

Regardless, at least the changes are coming soon. Facebook didn't reveal precisely when these changes would roll out, but we expect it to begin soon. For more info here's Facebook newsroom post: Reactions Now Available Globally | Facebook Newsroom

Google is About to Change the Way Ads are Displayed on Their Search Pages [Rumor]

Feb 23, 2016 - 3:34 PM - by dgstorm

According to the latest rumint, Google is getting ready to make a huge change in the way it displays advertisements on the search results page. The current method includes one or two ads at the top of the page, and several additional ads in the sidebar on the right. Supposedly, the new change will actually show 4 ads at the top and an even larger compliment of ads in the sidebar on the right. You can see an example of the final change in the screen-cap above.

The obvious effect this will have for some users is that they will have to scroll down farther to actually see their own search results. We can imagine this will not be a well received change, although advertisers will likely be happier about it. What do you folks think?
