Also, 50 mile range sounds great, but that's under "ideal" conditions, which happens roughly never. I'm curious what the range would be in the real world.
Earlier quoted context omitted.
All transmissions are end-to-end encrypted, unless you use the "shout" or "emergency" features which are, by definition, messages to everyone within range of you.
For those who care about security, is there an article to read for further details on that?
For encrypting the data as it's sent between gotennas we're using 1024 bit RSA. Not sure what level of detail you'd like.. but here are a few things to get you started!
RSA itself: http://bit.ly/1kDlTgP Cryptographic Services: http://bit.ly/1teLhPb More on CDSA (see above articles first): http://bit.ly/Ug2CLt
Much of our approach is fairly standard!

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…
They also explicitly forbid store-and-forward operations.
@Daniela I hope you aren't exhausted by all these, but X would be cool comments. If not: A walkie-textie would be cool, something less expensive and fragile (as emilv said) than a smartphone with a keyboard instead of a touch screen. Is there a serial interface to gotenna?
Can we get rid of this trend of having such media-heavy product pages? The HTML5 header video is nifty, but the page is ~20MB to load. Is that really necessary to describe a product?
Interesting ... 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?
We want to do that, but FCC regulations don't enable meshing (currently) on the bands we're using (151-154 MHz, aka the MURS band). We considered releasing a 900 MHz device that the FCC allows to mesh but then you only get, if you're lucky, up to 0.5 km range and it has to be line-of-sight. So we went with MURS because you can get greater range and don't have to be line-of-sight; the propagation characteristics are b…
