5G coronavirus conspiracists BURNING phone masts amid bizarre claim ‘radiation’ sparked killer bug

Posted by in categories: biotech/medical, health, internet, mobile phones

🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️


CONSPIRACY nuts are reportedly setting phone masts alight and targeting engineers after a bizarre claim 5G “radiation” caused the deadly coronavirus spread.

The theory originated last month after a video filmed at a US health conference claimed Africa was not as affected by the disease because it is “not a 5G region”.

Extreme high-frequency signals enable terabits-per-second data links

Posted by in categories: internet, mathematics, mobile phones

Using the same technology that allows high-frequency signals to travel on regular phone lines, researchers tested sending extremely high-frequency, 200 GHz signals through a pair of copper wires. The result is a link that can move data at rates of terabits per second, significantly faster than currently available channels.

While the technology to disentangle multiple, parallel signals moving through a already exists, thanks to signal processing methods developed by John Cioffi, the inventor of digital subscriber lines, or DSL, questions remained related to the effectiveness of implementing these ideas at higher frequencies.

To test the transmission of at higher frequencies, authors of a paper published this week in Applied Physics Letters used experimental measurements and mathematical modeling to characterize the input and output signals in a .

Energy-harvesting design aims to turn Wi-Fi signals into usable power

Posted by in categories: internet, mobile phones, physics

Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as “T-rays,” are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. However, to date, waves are wasted energy, as there has been no practical way to capture and convert them into any usable form.

Now physicists at MIT have come up with a blueprint for a they believe would be able to convert ambient terahertz waves into a , a form of electricity that powers many household electronics.

The U.S. wants smartphone location data to fight coronavirus. Privacy advocates are worried

Posted by in categories: biotech/medical, government, health, mobile phones, surveillance

The White House and the Centers for Disease Control and Prevention are asking Facebook, Google and other tech giants to give them greater access to Americans’ smartphone location data in order to help them combat the spread of the coronavirus, according to four people at companies involved in the discussions who are not authorized to speak about them publicly.

Federal health officials say they could use anonymous, aggregated user data collected by the tech companies to map the spread of the virus — a practice known as “syndromic surveillance” — and prevent further infections. They could also use the data to see whether people were practicing “social distancing.”

Some sources stressed that the effort would be anonymized and that government would not have access to specific individuals’ locations. They noted that users would be required to opt-in to the effort.

Federal Agencies Use Cellphone Location Data for Immigration Enforcement

Posted by in categories: entertainment, mobile phones

WASHINGTON—The Trump administration has bought access to a commercial database that maps the movements of millions of cellphones in America and is using it for immigration and border enforcement, according to people familiar with the matter and documents reviewed by The Wall Street Journal.

The location data is drawn from ordinary cellphone apps, including those for games, weather and e-commerce, for which the user has granted permission to log the phone’s location.

Taiwan’s new ‘electronic fence’ for quarantines leads wave of virus monitoring

Posted by in categories: biotech/medical, cybercrime/malcode, mobile phones

TAIPEI (Reuters) — Taiwan, which has won global praise for its effective action against the coronavirus, is rolling out a mobile phone-based “electronic fence” that uses location-tracking to ensure people who are quarantined stay in their homes.

Governments around the world are combining technology and human efforts to enforce quarantines that require people who have been exposed to the virus to stay in their homes, but Taiwan’s system is believed to be the first to use mobile phone tracking for that purpose.

“The goal is to stop people from running around and spreading the infection,” said Jyan Hong-wei, head of Taiwan’s Department of Cyber Security, who leads efforts to work with telecom carriers to combat the virus.
