G+_Mike Kelly Posted April 18, 2015 Share Posted April 18, 2015 Hey Padre, Brian and community, I'm striking out trying to find a broadcasting solution using pro transmitters at a National Park. Our group is trying to broadcast an HD video and sound tour "live" (using goPro 4 Black on a selfie stick + transmitter) from a paleontology laboratory into a visitor center theater. There are several modern construction walls and a distance of about 120 feet LOS. We almost get it done with using a Paralinx Triton, but it loses the connection at a critical location in the tour, when at the farthest distance from the Triton receiver. We can't hardwire a solution for various reasons having to do with homeland security and black helicopters. The park doesn't have internet access as it is too far from civilization, which eliminates something like the Livestream Broadcaster Mini which I think needs internet. I tried a DJI Lightbridge which works (!) but alas no sound is transmitted with this device, just HD video. I was wondering if I'm missing a solution with some combination of multiple wireless routers and some kind of video server running on a PC? Appreciate anyone's ideas.

G+_Eddie Foy Posted April 18, 2015 Share Posted April 18, 2015 There has been a lot of work on making mesh networks from the good old wrt54g's. The ham guys in Austin started this on a large scale/area. Place them around with a SLA battery and could be the ticket. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted April 18, 2015 Share Posted April 18, 2015 I am not sure if this is a case for goTenna Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted April 18, 2015 Share Posted April 18, 2015 Not sure what happened to my last comment. Might I say... It was completely awesome! The easiest IP solution is using VLC on a PC for the server and any computer, phone, tablet, Raspberry Pi, etc as the client. If that doesn't work (and assuming Windows), I've been using Icecast + BUTT, but that might only support audio. Either option will work on the local network without Internet access. The next piece to that would be the wireless network. I'm interested in the DIY mesh that Eddie Foy? is talking about, but there are commercially available products that will do a wireless mesh out of the box. Remember that with any IP solution you should expect a delay of a few seconds for compression and buffering. I've connected a DD-WRT router to another router wirelessly, so maybe that's all it would take for a DIY mesh... If you are a ham, the possibilities open up a bit but I wouldn't know any details.

G+_Jason Perry Posted April 18, 2015 Share Posted April 18, 2015 Mesh is great. You just need to look at the area you want to service and go from there. OpenMesh has a nice looking commercial AP. If yoy get a wap with 2 radios like the wifi pinapple you can one radio to communicate with a central node usibg a directional antenna and the other to service the clients. I am not sure if goTenna is developed enough to use for your solution. It boasts range but there is no mesh function to it because of FCC rules.

G+_Eddie Foy Posted April 18, 2015 Share Posted April 18, 2015 Using the HAM perks takes a big one away: encryption. (in the US) Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted April 18, 2015 Share Posted April 18, 2015 I just checked out that Triton transmitter. Are those antennas removable? Can the 2 dBi antennas with 9 dBi antennas? Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted April 19, 2015 Share Posted April 19, 2015 Here is a directional antenna that says it will work on that frequency range: Alfa APA-M25 dual band 2.4GHz/5GHz 10dBi high gain directional indoor panel antenna with RP-SMA connector (compare to Asus WL-ANT-157) https://www.amazon.com/dp/B00R1PA9EO/ And a pair of 9 dBi omni-directional antennas: http://goo.gl/hlwYFG Link to comment Share on other sites More sharing options...
G+_Mike Kelly Posted April 19, 2015 Author Share Posted April 19, 2015 We are going to try out another set of antennas made for a more expensive unit, but just haven't received them yet. http://www.paralinx.net/store/cloverleaf-antennas Lots of good ideas all around. Thanks everyone. I would eventually like to roll a more affordable solution. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted April 19, 2015 Share Posted April 19, 2015 I'm all for saving money. It usually means a bit more work, but sometimes worth it. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted April 19, 2015 Share Posted April 19, 2015 Mike Kelly check out Hak5's youtue page they have all kinds of information on attenas and large WiFi networks. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted April 19, 2015 Share Posted April 19, 2015 Just a quick warning, you have to go back 10 months to a year, but then you start finding videos like this, as well as attenas and other WiFi related content. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted April 19, 2015 Share Posted April 19, 2015 Yeah, Darren did some pretty awesome WiFi stuff. The Pineapple is a pretty awesome piece of hardware. Link to comment Share on other sites More sharing options...

G+_Jason Marsh Posted April 26, 2015 Share Posted April 26, 2015 Huh, there isn't one run of cat5 that could be repurposed temporarily? It's a long shot, but I'd bet you could get a stable wifi link going without any special software. One thing about single-channel, 1x1 radios is that you take a serious bandwidth hit if they have to relay between nets. Not a problem for a lunatic like me with no less than four WRT54G just for such projects :) Link to comment Share on other sites More sharing options...
