> GoTenna, a Brooklyn-based hardware startup, has a modified, smartphone app-based approach to staying in touch at a lower cost when cell service is shaky, no satellite connection required. The device, a thin 2-ounce wand that can be strapped to a backpack or belt loop, connects to a smartphone app via Bluetooth low energy (LE). Slide out the antenna and power on the device and you'll then be able to send messages and GPS coordinates from your smartphone to others connected to a GoTenna. The company offers downloadable, high-resolution offline maps for referencing transmitted location data.

> GoTenna doesn't give your smartphone LTE-style data, so no Twitter scrolling or Facebook browsing. What it does is create a low-frequency radio wave network for its iOS and Android app that can last around 1 mile in skyscraper-filled urban areas, but up to 9 miles in most outdoor situations like hiking and camping. If you're climbing or, say, out skiing, it shoots from 9 miles to as high as 50 miles once you start ascending to higher elevations.

> What is goTenna?

> Short story: goTenna is a small device that allows you to use your smartphone to send and receive messages and share your GPS location with others even when you don’t have service.

> Longer story: goTenna is a small, rugged device designed to make “No Service” no problem. Just pair your smartphone with a goTenna and communicate off-grid with those near you who also have goTenna, anywhere on the planet, regardless of access to cell reception or wi-fi. goTenna allows you to send and receive texts and share GPS locations on beautiful offline maps, without ever relying on central connectivity. Depend on it in all kinds of situations: when hiking in remote areas, traveling, attending music or sporting events or during an emergency. Plus, because goTenna is end-to-end encrypted, it’s not just for when you’re off-grid, but when you want to be.

Meshnets are at a viable small-scale stage, don't be suprised that there's not much news on them. Big ol' ISPs aren't too keen on decentralization.

> Is goTenna a mesh network?

> No. While we would like to mesh, current FCC regulations don't enable us to store-and-forward messages, which is why we've focused instead on getting you great point-to-point distance over the long-range 151-154 MHz frequencies.

so you're using a radio with a battery and multiple radios to talk via radio to a radio with a battery and another radio on it

xibit just imploded.

nevermind that it only puts out 2 watts on a band that has 5 whopping channels on it for use.
>> No. 6482 ID: d444df

Now,if it were something narrowband like psk31 I could see that, but broadband? Lolno.

You are literally the second worst kind of poster that exists in this world.

On topic: As neat as this thing might be to play with, I don't see this product going anywhere. Maybe once they get it to mesh and relay, but until then it doesn't do anything useful that FRS doesn't already do. Sure, there's the map/gps thing, but who is really worried about tracking their friends in real time like that.

I mean, who needs to send texts, to one or two other people, out in the middle or nowhere, who happen to have the same device.

I think anyone who would be interested in this product already has better communication gear that doesn't have the range and compatibility issues of this device, even if it doesn't have all the features.

I may be wrong, but I feel like this thing is a solution in search of a problem.

Probably, but can't help think something like this would have been useful to protestors during the Arab spring. Since the protests were arranged via twitter they were also easily monitored; something like this would seem to get around that.

Plus the average sign waver isn't likely to know much about radios, but will know how to use their cell phone.

Hey I'm not a smart person, but would this device let me have secure coms between me running around and my wife at home without everyone being able to listen in like a radio?

please use small words
>> No. 6488 ID: 7fcde8

Running digital =/= encrypted with user-definable key


It will *NEVER* mesh nor relay. Not in the current band that they wish to exploit (which by the way is just a cunthair away from the FRS Band, the only advantage here is that it's 2 watts of output instead of .5 on FRS


No. Secure is an improper term anyway. Cellular tech is encrypted with a long enough key that a layman would have to record, then spend quite a long time to crack it... government agencies just get to tap it where it's unencrypted.

This isn't encrypted at all, at BEST it's digital which isn't encrypted, it's simply transmitted digitally. It actually ends up having worse range than an analog transmission due to it... shit will sound good and data will work up to a point of signal degradation, then it will just not work. Not in and out like that radio station you have to move the antenna to get, flat out poof gone.

As long as you have the digital mode (which while able to be proprietary, has to be published) you can listen to things. The question is what mode are they going to use... some aren't free to use and then the company pays royalties for every radio, but those are the best supported ones.

Radios are actually easier than having to fuck about using twitter. You are the network as long as you know a 6 digit number and how to put it into the radio... unlike a phone where you're relying on something else. This is adding another point of failure into a communications system that you have to manipulate and maintain... but whatever. Go ahead and buy it, I'll be laughing and talking to who I need to talk to.
>> No. 6489 ID: d444df
Look at the ID then think about what I usually have in the namefield.
I try ;)

Now that I think about it, one would probably be better off using a couple crappy linksys routers, DD-wrt, and a very directional antenna. At least it would have the added benefit of a narrow beam, and point to point encryption.

If you're looking for fixed ip-comm, you could just buy a set of these. http://www.amazon.com/gp/aw/d/B004EHUTNI?pc_redir=1410758525&robot_redir=1

Had to look up the MURS restrictions because it's not a band I've really had an interest in.

As far as I can tell they went with it because it's about the only unlicensed band (other than 2.4/5ghz) that allows textual communication without a license. Personally, I think the FCC should get with the 21st century and start allowing digital modes on maybe a subset of CB, GMRS and even FRS, but that's not going to happen any time soon.

As >>6493 pointed out, you'd have more luck in the higher frequency unlicensed bands. Better and changeable antennas, better broadcast power, lots of applications and legal encryption.

Another "PRE-ORDER NOW!" product is a phone backpack with SDR. Sounds like they want to sell an unlicensed, a ham and a public safety version. Honestly it'd be nice to see some progress in consumer radio tech but the devil is always in the details. They are going through FCC certification which is promising. They *claim* all text will be encrypted but that's straight BS for the ham and unlicensed version.

"Our goal is to build a device for multiple applications. For the consumer application, the device will operate in both MURS and FRS/GMRS, FCC part 95 devices. For Amateur Radio HAM applications it will operate on the 2m and 70cm (440) bands, FCC part 97 devices. For commercial, industrial and public safety applications it will operate in the bands outside MURS, FRS/GMRS, 2m, and 70cm, FCC part 90 devices."

Can't wait for someone to have a give a big "fuck you" to the FCC and introduce a mesh network dongle that ignores their faggy rules. Fuck regulations, they can't arrest everyone.

I'm getting some Ubiquiti stuff soon as well.

Seems like a decent company. Mind you, this is just a pleb house wifi setup, but I have used their products at work.

UniFi best AP hands down
>> No. 6749 ID: 47b29b

A good chunk of the 900MHz spectrum is unlicensed, and it can be used to send all kinds of data, including encrypted data. Unlike MURS.


Ubiquiti is making a 900MHz WiFi transceiver now for long range point to point networking backbones for small companies. No licensing required!

This thread reminded me of this article:

It's no surprise that the NSA likes to have their fingers in every pie and toss in a shitton of salt (see NIST crypto standards and this link: http://cryptome.org/nsa-sabotage.htm ), so seeing this article kind of makes me feel as though it is a possibility, as tinfoil hat as that sounds.

Anyways, the comments are a decent silver mine. Enjoy the read.

For a less tinfoil hat bit about this tech, read this:

An interesting idea I had no clue existed.

Also, on the subject of Ubiquiti, I found out that you can be even more paranoid:

My body is ready.

Wise words, but I'm more of a 1/φ kind of guy... well, when optimistic.

Basically, OpenBSD is known for being a minimal OS that aims for maximum security by having proactive security practices.

As this is an OS, they have support for hardware. OpenBSD, like many other OSs, splits up support based upon the CPU architecture and sometimes based upon a particular popular platform ( http://www.openbsd.org/plat.html ).

Octeon is a version of a MIPS64 processor that the EdgeRouter Lite uses.
