The volunteers blanketing cities with wireless internet

From the volunteers’ position, a supernode—a multi-­antenna monstrosity responsible for linking much of the network on the Lower East Side to nodes in Brooklyn—was barely visible atop the Sabey building. Before them, in the shadow of the supernode’s signal, lay four residential buildings too short to get an angle on the antennas above them. For the next two and a half hours, Boning and Espinosa, along with another volunteer helping remotely with configuration, would work to create a route for internet traffic to those buildings via the node on the rooftop they had climbed to. “As soon as I learned what the Mesh was,” says Espinosa, “I was like, ‘Oh, this is awesome.’” 

In Lower Manhattan, which has an underground fiber-­optic network, residents still rely on wireless connections to route their internet from the fiber up to their apartments. For this step, renters are often restricted by building contracts to

Xiaomi launches an 80-watt wireless charging method.


Xiaomi

A new challenger joined the ultra-fast charging wars on Monday, as Xiaomi unveiled an 80-watt charging system it says will fully revitalize a phone battery in less than 20 minutes. 

The Chinese phone maker says its new charging method, “80W Mi Wireless Charging Technology,” can charge a 4,000mAh battery to 10% in one minute, 40% in eight minutes and 100% in 19 minutes. This is a step up from last year’s 30-watt charging tech, which refills a similar battery size to half in around 25 minutes, according to the company. 

Xiaomi didn’t specify how the charging method works or whether it will ship with a device. But the Chinese-phone maker does lay claim to the title for shipping the fastest wireless charger with a commercially

Amazon Needs This Wireless In-Flight Drone Recharging Tech For Prime Air

Amazon’s drone delivery service delivered its first package on December 7, 2016. Almost four years later, it’s still a “future delivery system.”

What’s missing?

Probably something like wireless in-flight drone recharging from the tiny Portland-based Global Energy Transmission, which has demonstrated fast wireless charging for drones that gives delivery, inspection, or surveillance drones essentially unlimited range.

Charge time? Just six minutes.

“Like with a regular car when you need more gas, you just go to the closest charging station,” Leonid Plekhanov told me on a recent episode of the TechFirst podcast. “Spend a few minutes there to fill in your tank and then you just continue your mission.”

We’re mostly familiar with wireless charging for smartphones. That’s slow, generally using about five watts of output via inductive charging technology.

The promise of 5G wireless: Speed, hype, risk | Business News



AP Explains: The promise of 5G wireless - speed, hype, risk

A much-hyped network upgrade called 5G means different things to different people. To industry proponents, it’s the next huge innovation in wireless internet. To the U.S. government, it’s the backbone technology of a future that America will wrestle with China to control.




A much-hyped network upgrade called “5G” means different things to different people.

To industry proponents, it’s the next huge innovation in wireless internet. To the U.S. government, it’s the backbone technology of a future that America will wrestle with China to control. To many average people, it’s simply a mystery.

What, exactly, is 5G wireless — and will you even notice when it comes online?

What is 5G?

5G is a new technical standard for wireless networks — the fifth, naturally — that promises faster speeds; less lag, or “latency,” when connecting to the network;

5G, touted Tuesday on the screen of Apple’s Steve Jobs Theater, is the biggest new feature in the iPhone 12 lineup.


Apple

This week’s arrival of the iPhone 12’s, which features 5G as its marquee addition, brought to the forefront the US carriers that have been rapidly building out these next-generation wireless networks. Verizon CEO Hans Vestberg shared the stage with Apple CEO Tim Cook during the launch, while competitors T-Mobile and AT&T didn’t even warrant a mention. That rivalry is going to heat up as these carriers start rolling out deals and touting their 5G coverage in a radical new wireless world. 

Which could be good for you.

Apple is going all-in on 5G as a selling point for its four new iPhones, to the extent where super-cuts of all the

Wireless Technology Comes to Your Body

The same technology that has been used by the Navy for communication: sonar, could be used to treat heart failure, diabetes or other illnesses.

University at Buffalo, a leading research center is working on the ability to use this technology for medical diagnosis and transmitting information.

The advancement relies on sensors that use ultrasound. Ultrasound has been used by military submarines and in medical offices. Similar to how the navy subs communicate between each other, medical devices such as a pacemaker could communicate and transmit pertinent data by radio waves. Exploration in this area has been in development for over 10 years. However, the focus was on electromagnetic radio frequency waves, similar to ones in GPS units or cell phones. Drawbacks of electromagnetic radio frequency waves include the amount of heat produced and energy that is needed. Since the body is made mostly of water, over 65 percent, electromagnetic waves … Read More
