I'm just wondering if anyone has tried this. I have talked to some people that said this could give me a range of well over 1km, and plenty of bandwidth for data up/down and video downlink.Anyone…Continue

James F. replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Would it be better to use only bluetooth or only wifi? Which one is better for this application?"
Jeremy replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"true not in the traditional sense its just a direct link between the plane and the GS. But I do use wifi onboard for other things. as well as bluetooth."
Boz replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Jeremy,
I take it you are not really using wifi (802.11), only the chipset right?"

"Check with TJ Bordelon (one of our members).
I know he has been working with wifi for dozens of years now.
Check out his site."
Mike W replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Wow thats fantastic! And yes your right about boosting the power and frying the chips, I've read about people bricking them online.
Will you be posting a build log of your Overo Fire anytime soon? I bought one of those boards a few months ago…"
Jeremy replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"That seems like an awfully big footprint to use in a plane though. Those boards are not that small, even though they dont weigh much. Just my opinion. With my gumstix I still have yet to pass 35% cpu usage and its streaming video sending data to the…"
Mike W replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Has anyone tried boosting power on a Linksys WRT54GL after flashing the firmware with DD-WRT or OpenWRT?
I own a few 54GL's (awesome routers by the way) and the first thing I do is flash the firmware with DD-WRT. The additional functionality is…"

Andre S replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Thanks for the optimistic news :)
Both the macbook on the ground and the gumstix overo in my setup run linux (macbook relatively recent Ubuntu with updated kernel). However, I had a headache to get one of the wifi adapters working at all and needed…"
Jeremy replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"patch the drivers your using and use the link on a linux box most of these issues will disapear. There are tons of driver patches for linux that solves these issues. I use a adhoc setup from my UAV to my GS mine goes from a gumstix over/ UDB combo…"

"I wasn't sure, -thats why I asked for clarification, since each has it's own requirements and complications."
Andre S replied to Andrew c's discussion Using wireless internet(802.11) as transmission protocol"Well, my intention originally was using the link for video and telemetry (so latency is not really an issue as long as it stays under a couple of seconds or so)"
