5G cellular networks are able to transmit data at very high speeds, with incredible spectrum sharing that allows multiple 5G towers to operate in close proximity without their transmissions clobbering one another. Read the rest

This Yootech wireless charging station works just fine and eliminates the need to keep multiple cables on my desktop.

Offering 7.5W for Apple phones and 10W for Android, this charging puck works to charge any of my Qi-charging enabled devices. This lets me put my phone or tablet on the same charger, and lets me simply lay them down and not have to plug them in.

Less cables, less trouble.

This puck does not charge an Apple watch.

While 5G mobile networks promise to provide tremendous wireless speeds with low latency, they may also make it more difficult for meteorologists to provide weather forecasts. That's because 5G's neighboring frequencies are used by satellites that detect water vapor in the atmosphere, data that informs weather models used by meteorologists. From Nature:

Astronomers, meteorologists and other scientists have long worked to share the spectrum with other users, sometimes shifting to different frequencies to prevent conflicts. But “this is the first time we’ve seen a threat to what I’d call the crown jewels of our frequencies — the ones that we absolutely must defend come what may”, says Stephen English, a meteorologist at the European Centre for Medium-Range Weather Forecasts in Reading, UK.

They include the 23.8-gigahertz frequency, at which water vapour in the atmosphere emits a faint signal. Satellites, such as the European MetOp probes, monitor energy radiating from Earth at this frequency to assess humidity in the atmosphere below — measurements that can be taken during the day or at night, even if clouds are present. Forecasters feed these data into models to predict how storms and other weather systems will develop in the coming hours and days.

But a 5G station transmitting at nearly the same frequency will produce a signal that looks much like that of water vapour. “We wouldn’t know that that signal is not completely natural,” says Gerth.

America's major cellular carriers publish maps showing that virtually the entire state is well-covered, with solid signals and 5MB/s internet speeds, but Vermonters know that this is totally untrue. Read the rest

In The State of 4G Pricing, Finnish researchers Rewheel identify the US as having some of the most expensive wireless data (fifth highest prices) in the world, and they predict things will get worse thanks to looming mergers in the already super-concentrated wireless sector. Read the rest

When wifi first appeared, it was secured by something called "WEP" that was so laughably weak that many people believe it was deliberately sabotaged by US spy agencies (who have a history of sabotaging security standards in order to preserve the ability to spy on their adversaries). Read the rest

Five years after activists forced Seattle's mayor to return the city's surveillance drones to their manufacturer, the city has announced that it is terminating its warrantless mass-surveillance program altogether. Read the rest

A leaked White House Powerpoint deck published by Axios reveals that some elements in the Trump administration are trying to sell a plan for the US government to build the nation's "5g" wireless infrastructure, hardened against Chinese surveillance and attacks, and then lease access to the private telcoms sector; the network architecture could then be reproduced and given to US allies to help them defend themselves against Chinese attacks.

Why we secretly love our cords. Tamara Warren:

There’s a certain security in the cord. It’s the idea of connection, perhaps even dating back to our days in the womb. ... A battery, no matter how sophisticated, is fleeting. When we have our cords with us, we are in constant pursuit of power, even when we are fully charged, as a form of security. We often discover our misfortune — the loss of power — when it’s too late. The opposite of being fully charged is dead. Cords, and our attachment to them, have taken on a metaphor weighted in existentialism. There is anxiety in being too far removed. We are in a relationship with our cords.

Allow me to retort!

The cord is a chain. It's the imposition of place, perhaps even dating back to our days in the mire. ... A cord, no matter how comforting, is invariable. When we wander, we are in pursuit of freedom; we often discover our misfortune — the tether — too late. The opposite of mobility is stasis.

Honestly, I hate cords so much! The first trillionaire will be put there by batteries. Read the rest

An outstanding post on the EFF's Deeplinks blog by my colleague Ernesto Falcon explains the negligent chain of events that led us into the Stingray disaster, where whole cities are being blanketed in continuous location surveillance, without warrants, public consultation, or due process, thanks to the prevalence of "IMSI catchers" ("Stingrays," "Dirtboxes," "cell-site simulators," etc) that spy indiscriminately on anyone carrying a cellular phone -- something the FCC had a duty to prevent.
