    Non-centralized messaging system

    This looks really interesting. Sort of a Bluetooth Private network, can interface over wifi and cell as well. And while seeking pricey, it would be worth it depending on. Your intended uses.

    Look useful for hunting groups, emergency situations, and when areas of cel towers are turned off to prevent communication from unwanted people, or during events.

    It looks like they might be trying to do a big push in PR as well. If it works there, they've really have proven their model, capability, and product should explode.

    Due to the alternative nature of the product, I picked here instead of gear junky.

    I have to admit it looks pretty cool. Though my question is what is the range on a single pair of GoTennas? (The website doesn't really say.) I mean true they work better as a mesh... but that's an ideal situation. Life isn't always ideal and can't really rely on people around having them. (Especially not at first.)

    I don't really understand what void this is supposed to fill, you can use encryption with on-grid networks, on grid-networks are more efficient and if I really need off grid networks I wouldn't even bother with a common cell phone and just go with a satellite phone (more efficient and still can use encryption) or just get UHF/VHF radios.



    Sounds like basically a way for millennials to experience two way radios without actually having to go through the trouble of experiencing two way radios.

    For me, what it seems to try to do is allow users to keep using existing hardware (their cellphones) even when the main cellular network is down or flooded due to emergency situations. (Or like they show in demos, when travelling and people are spread out.) Satellite phones could work but not everyone has one and they can be costly. Plus if the main phone lines are down/flooded anyway even with a satellite phone you might not get through.

    Another important difference between this and a 2 way radio is that your message is going to the other person/group. On a 2 way radio anyone can jump in and respond. Which at times can be useful, but then at other times if you only want to talk to your friend having some other person on the line constantly interjecting can be a real nuisance.

    Range is critical, but I see the use for areas without cell service. Hunt, work, keep in touch with family . . .

    Nowadays you can buy UHF/VHF radios for cheap, I think technically you need to be licensed on those spectrums so it keeps people off the airwaves unlike CB but it's not really enforced.

    There's no technically about it. Frequency spectrum is managed by Industry Canada (changed their name to something else when Libs got in) and the only VHF/UHF you can use unlicensed is FRS and GMRS. And even then only with equipment certified for use on those frequencies. Any cheap Chinese radio you buy off eBay or wherever is 100% illegal for you to transmit on. The only exception being in situations of life and death or severe injury as well as major property damage.

    The amateur radio (ham radio) license to use them is pretty easy but not easy enough as it covers other sections that only pertain to those interested in HF (world-wide radio comms). I have and will continue to advocate that licensing/examination for UHF/VHF only amateur radio be made easier to make it more accessible. That's a win win for everyone. Unfortunately these things move slowly.

    Oh, and the lack of enforcement is simply due to there not being staff to monitor these frequencies. Hams will report unauthorized use if they hear it and they will have triangulated you first. But Canada is big, if you live in rural Canada and are intelligent about what frequencies you use you likely won't get caught. Still, a license is worthwhile just for the knowledge.

    Most casual users aren't going to bother with licenses. I mean it might not be correct, but if done in the right way you aren't going to be disturbing anyone or causing any issues. I know plenty of people who regularly use the cheap Chinese UHF radios. Guys out on hunting trips, off roading, doing a big road trip traveling in a convoy. They would use CB but CB sucks ass, it's full of idiots talking about BS non stop, making donkey noises, etc.




    About this triangulation stuff, is that only the equivalent of range nazis in ham that do that or everyone? Do they need special gear to do that or is it something anybody can do?



    Lastly, (Enemy of the State reference), if these guys are good how long before they get you? Say you were a dumb ass playing music over unauthorized frequencies in a city like Toronto. How long would you think before they have you made?

    It looks like the first version was 900Mhz area, but had issues from so many people. Next versions, which seem to be the actual production ones, are different frequencies. I think they are claiming up to about 9km, ideal conditions. So definitely "Cobra handheld" competition at least.

    I do like the fact it eliminates another charger, and the cords are more likely to be found outside cities and regular business hours. Gas stations sell most types of charge cords nowadays.

    Another advantage over the handhelds is that the user is operating something they are familiar with, and you don't need to interrupt what they're doing to get the message to them. Have phone on silent and you can text that the trophy buck is going by behind them, not where they're looking. Trying that on a handheld, likely game will bolt...
