What band does this operate in? Do I need a license to operate one in the EU?

#12Does 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?

#13The 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.

#14I slid the range slider all the way down as I'm in the, notoriously flat, Netherlands. Most of the time I'm in a city, Amsterdam, and then I'd have a range of 0 miles. Is that correct? That does not sound very useful to me then. Can someone confirm that this is correct?
I think their slider is a bit misleading as if you have the slider at 0ft then the range is 0 but if you have it at 5ft then the range is up in the miles. I think their point is that if you need to use this then you may need to seek slightly higher ground... or some stairs...
Most people are 5ft tall!

#15From the FAQs: "Use our free app to type out a text message or share a location."
Ugh, it's a lot less magical than they make it seem in the video.

#16Let's build our own cellphonenetwork, where we all have something like this and it's like a giant p2p network!

#17Interesting ... does this do any kind of store and forward or relaying? Say I send a message to a friend who happens to be out of range, but there was another GoTenna user who neither of us know, but who is in range of us both, will it relay the message via this 3rd party (encrypted) or is it purely a direct connection between sender --> receiver?
For now the chances of finding a third GoTenna user is quite low. In the future though this could be an alternative private Internet. A BitTorrent client could be a hit.

#18So 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.

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 (for instance if the relay-phone receives on the goTenna a message from A saying "SMS foo bar" it could relay the "A says: foo bar" via SMS to .

#20Is 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!
