G+_610GARAGE Posted June 13, 2015 Share Posted June 13, 2015 This is neat. Lossyish wifi for fpv. Originally shared by HACKADAY Normal WiFi is not what you want to send video from your quadcopter back to the first-person-view (FPV) goggles strapped on your head, because it’s designed for 100% correct, two-way transmission of data between just two radios. Transmission of analog… http://hackaday.com/2015/06/13/wifibroadcast-makes-wifi-fpv-video-more-like-analog Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted June 13, 2015 Share Posted June 13, 2015 "100% correct, two-way" is true of TCP, but with some allowance for dropped frames/packets UDP is a better fit, and doesn't require a divergence from standard 802.11 protocols. Reinventing the wheel for the sake of reinventing? Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted June 14, 2015 Author Share Posted June 14, 2015 I could be totally wrong with this, but I believe what they are trying to do is to bypass some of the lower wifi protocols to allow for more drop and incomplete packets. If you are using UDP, but the receiver only gets half the packet from the router, the receiver is going to ask the router for a resend, no matter what type of packet is being sent.

G+_Jason Marsh Posted June 14, 2015 Share Posted June 14, 2015 Eh, methinks if your signal strength isn't enough for reliable throughput you should be looking for a stronger and more sensitive radio set. Or a different band altogether. I suppose you might decide to re-purpose existing tech to that end, but I don't see why you wouldn't push the current protocols to it's limit first. Reliable 802.11 links have been made at much farther distances than entertained in that link and those for the project. It's all a matter of SNR and receiver sensitivity.
