DailyDirt: Is There A Better Word For Wireless?
from the urls-we-dig-up dept
Wired communications are obviously a more reliable connection than any wireless technology (when a wired connection is actually possible or practical), so wirelines aren't going away any time soon. (Well, unless you live on an island off the coast of New Jersey.) But wireless technologies offer some pretty clear advantages, too. Maybe we'll discover some way to make wireless connections just as solid as wired ones, but until then, here are just a few advances for transmitting information without a wire or cable.- If you're really paranoid about someone intercepting your home WiFi network, maybe someday you can set up a wireless network that transmits via visible wavelengths (so a wall would effectively block out would-be eavesdroppers). It might be annoying to set up a wireless network like this for more than one room, though. [url]
- Cheap, high-bandwidth transmitters for satellite communications in the 42-25 GHz range might be nice to have in a smartphone. A couple DARPA teams have demonstrated the feasibility of millimeter-wave power amplifiers on silicon chips for the first time. [url]
- T-rays (aka terahertz rays) have been shown to break the 3 Gbps barrier -- but a T-ray based WiFi network would probably only achieve 100 Gbps and have a range of about 10 meters. FYI: T-rays are part of the unregulated spectrum, and they can penetrate some materials (but not metals or water). [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

stupid shadows!

I recently read an article about NASA experimenting with laser transmission technology. Of course, line of sight between the laser transceivers is probably necessary.

Seriously?
But windows wouldn't. Also, it'd be fucking visible, so unless you were in the mood for a Pink Floyd Planetarium Experience, godsdamn annoying.

Food for thought.
X-Ray back scattering works by catching x-rays bouncing back from something, you can do the same to light coming out from a window and see what the TV is showing or translate that to a data stream.
Idea: buy or make a circular knitting machine any will do and instead of a fiber thread use wire, there know you can make wire meshed tubes all day long, which become faraday cages.
e.g.:
Youtube: Making A Hat in less than 30 minutes on the addi Express Knitting Machine
by SkacelKnitting
Imagine instead of a hat, you are doing just a wire tube.
Cookies for you if you find the video of the geeks from Maker getting a flatbed Brother knitting machine to connect to a computer to make it do patterns automatically.
Why would you be looking at knitting at all you ask?
Well, I didn't, I start looking for how to produce biopolymers and then I found out about how rayon is made from cellulose that pass through a spinneret into an acid bath and somehow looking at the machines I found out how knitting machines work, specifically how the needles for those machines are constructed and function, I drifted from one subject to the other and end up looking at people making socks and hats OMG! now I am looking at how clocks are made using DEM that took me to another place about how to produce stents and the designs used which gave me an idea to produce some using aluminum cans in a large scale to see how they work, and I have to look up unclogging of pipes to see if they work the same as the guiding system used by the doctors that use a catheter to put things in you.
Frak me, sometimes I hate the internet.

If you're that paranoid...
