If Speed Is Your Thing, South Korea’s Got You Covered

warp-speed-dog-frogman

South Korea’s science ministry has been discussing their next generation of mobile service, and the numbers are dizzying. While the current 4G service there already trumps that of pretty much anywhere with their 300 Mbps “3band-LTE-A” connections available by the end of the year, that still pales in comparison to what they have planned for 5G. See, by 2020, there are plans for speeds 1,000 times greater! This means you could download a full 800MB movie in one second. What? One second? That’s right, in the time it took you to read these last few words, you could have downloaded a full movie. If HD is your thing, you would only have to spend 5.12 seconds to grab 4.6GB.

What’s more, the service will be available even on bullet trains that travel 310 miles per hour. What? They have trains that ravel that fast? We sort of knew this, but it’s only when you start looking at the whole picture that you realize just how far behind our infrastructure is, right here in North America. 310 miles per hour bullet trains, 5G cellular service that downloads an HD movie in 5 seconds? Come on… they’re past making us look bad, now they’re just gloating.

This Is What Cellular Signals Would Look Like If You Could See Them With The Naked Eye

smcell-signals4

The above is a visualization by Nickolay Lamm that shows us what Chicago would look like if cellular signals were visible with the naked eye. It’s trippy and fascinating, and above all it isn’t just a fanciful interpretation, but is based on some solid understanding of how our cellular infrastructure works. “Danilo Erricolo, Professor of Electrical and Computer Engineering, University of Illinois at Chicago and Fran Harackiewicz, Professor of Electrical and Computer Engineering, Southern Illinois University Carbondale—who consulted on the psychedelic project—explain:”

A regular, hexagonal grid of cellular base-station sites is conceptualized for Chicago [above], with stations at the corners of the hexagons. The area within each sector antenna radiation pattern has different users being assigned different frequencies and their signals combine to form a single perceived color in that instant. Different channel combinations from sector to sector are indicated by different colors. The channel combinations shown are not static, but rather change rapidly in time as different users are assigned different channels. But, if you were to take a photo of these rapid changes, you’d likely see a wide array of colors as seen in the illustration. Near the downtown area more users are likely to be found and the hexagonal cells are smaller to serve approximately the same numbers of users found in larger cells elsewhere. Antenna signals extending beyond the original cells provide coverage over part of Lake Michigan.

We are surrounded by an always-on cacophony of electromagnetic radiation; it’s a blessing that our eyes are only able to see a small sliver of it. Visualizing it only serves as a fascinating reminder of this.

Room Spy Bug Audio Surveillance Listening Device

listening-device-1

Let’s not get into the legality of this device. But if you have a need to listen in on conversations for whatever reason, the Spy Bug Audio Surveillance gadget pictured above should do the trick. About as small as a pack of matches, it accepts a SIM card, which means you can just call it anytime you want to eavesdrop. Better yet, you can set it so that anytime there’s a sound above 45dB within 10m, it calls you!

- Use with any mobile SIM card (We recomend Verizon Wireless): Insert the SIM card; conceal the device where it can’t be seen; dial the SIM card phone number from your phone; now you can listen in!

Again, not sure how legal something like this is in your jurisdictions, so use wisely. It’s $60.

Dumbest Gadget Ever Arrives: Blutooth Handset TK2

By David Ponce

“Yo dawg… we heard you like phones. So we gave your phone a phone.” Yeah. That’s pretty much what’s going on here. See, the Blutooth Handset TK2 connects to your cellphone through Bluetooth and all it does is allow you to speak (and listen, duh). The thing is… you’re supposed to hold it in your hand. Like a phone! So in a way, it’s a smaller phone that you use… to use your phone. It has no other point. It doesn’t free your hands, it does the opposite.

Granted you can pair it with more than your cellphone, so perhaps this can be a tiny VoIP device… Or something. It does feature Bluetooth v2.1, which means you could pair it to your cellphone and something else simultaneously. So maybe you can eke out a use that way. Like if you’re at home and are taking Skype and cellular calls.

But still, come on!

It’s $23.
