What band does this operate in? Do I need a license to operate one in the EU?
Seems to be shipping to US & Canada only for now.

#23So it's just a walkie talkie that has bluetooth? You can buy decent walkie talkies for £20, I'm not what paying £100 is getting me.
From the few details [1] I've been able to find it seems like it's unusable in the UK anyway as it uses 151-154 MHz, which is a licensed band. If they moved it up into the 433ishMHz unlicensed band their range claims would all have to be revised.

#24No voice? That lost all of my interest. So now I need to tap out a message on my expensive, somewhat fragile smartphone with dirty fingers while losing all sight of the road for a minute. Instead of a sturdy walkie-talkie where I can hear the voices of my friends, talk efficiently in real sentences and I can look where I'm going all the time.

#25Is it me or is their a guy in the video getting baked? Not only that it is around the security part where he is getting in contact with his mate "Jason Greengrocer" about getting more. That part makes me happy!
I think they are quite deliberately pointing out that dealers can communicate with their users in private, outside of law enforcement spying on them [Use case A1].

I like the fact that can be publicly advertised as a unique selling point.

#28The part I think is missing is a connection back to the cell network so that you can give people in more remote locations the ability to text the rest of the world using this as a link. I don't see the 2-user walky-talky being that useful, but I would happily leave this and an extra phone in my car if it meant getting text functionality as I hike out 20 miles.
> The part I think is missing is a connection back to the cell network so that you can give people in more remote locations the ability to text the rest of the world using this as a link. While reading their FAQ I thought of that, and if the API is open sourced or reverse-engineered, it shouldn't be too difficult to write a smartphone application which would act as a relay between to goTenna and the phone network (fo…
It could be a whole lot simpler than this. (And a whole less secure.) In high school I had a server running that scanned email for a keyword and my cellphone number; I didn't have a smartphone. So I texted a keyword and some code to my email. Then my server would read the email, see it contained the keyword, then interpret the rest of the code I sent and execute it. This would be insanely easy (and not too secure) to implement on Android for instance.

#29I wonder how hackable these will be, or what kind of bandwidth you might be able to push. I could see putting one at my home and one at my office to create a poormans wireless bridge.

#30Does anyone have details on the RF layer? What band does it use? What emission type does it use? What bit rate does it send at? What happens when 1000 of these are in the same place at once?
From what I am reading, it runs on Multi-Use Radio Service (MURS). i.e. 151-154 Mhz spectrum.
Excerpt From https://apps.fcc.gov/edocs_public/attachmatch/FCC-02-139A1.p...
Under the revised rules, MURS units are: • Permitted to have detachable antennas; • Permitted to have external antennas up to 6.1 meters (20 feet) above a structure or 18.3 meters (60 feet) above the ground, whichever is higher; • Permitted to have a total power output (TPO) of up to two (2) watts (instead of two (2) watts effective radiated power); • Not permitted to be used as cordless telephones, radiofacsimile (imaging), or for continuous carrier mode operations; and • Not permitted to be used for repeater operations
Without a repeater, I would assume it is very difficult to imagine a hop-by-hop network?
