If however your Internet radio, connecting to the Drone, is at Channel 1 (which is I believe its default) then you'll want to set your Home/Nexus channel to 11, as far away as possible, to minimize the possibility of RF interference.
Got that all spread out... Drone defaults to channel 6... Hawking defaults to "Auto"... the red is our home WiFi... the home WiFi is in the next room... the drone is sitting about 15 feet away on top of the TV... the Hawking antennas are sitting right on the coffee table about 5 feet away

Have you taken the repeater apart and got any pictures of the chips inside the repeater? So maybe we can see if their is any more info on what it uses?

Can u take a picture with what it looks like with those flashing indicator lights ? It looks like their is 2 rows of led ? I thought the bottom row would have been a signal strength indicator?
Got it for a hundred bucks off eBay new sealed box... I forgot about my mounts dude... I got the repeater all mounted onto a stand vertically and it's not so easy to take apart so the internal pictures will have to be at a later date... sorry bout that one

I finally tried my EnGenius EOR7550, and after all my hand-wringing about "what modes to use" it turns-out that it works out-of-box also. Too windy to do any flying today, but I walked the Drone out to about 250 feet (maybe farther than I would ever fly it) and still had full signal.

Yeah my Drone is on Channel 6 also, for some reason I thought it'd be channel 1. Anyway I set Radio2 to channel 11.

I gotta make some pretty pictures like yours! Since I jail-broke my iPad I have a couple wireless apps (that Apple doesn't allow!). Have fun with your new toy...

How do you know you had "full signal" the WiFi indicator on freeflight doesn't show the connect with the drone... it shows the iPad connect with the repeater... does the EnGenious have it's own display??

That's one of the problems we been trying to solve when flying with a repeater... there's no way to know when you're about to lose signal because there's no display showing signal strength from the drone to the repeater

Oops! :oops: I wanna say "are sure about that?" but no doubt you are--I shoulda had an extra cup of coffee this morning! FF really oughta report what the Drone is seeing, shouldn't it. Seems like a no brainer; just one more piece of telemetry to send-back from the Drone. But an easy corner to cut for Parrot, to just look at the controller data.

I can inspect the true signal strength using a PC to the EnGenius, but that's not going to help me in the field. At least, I won't want to always have to set-up my netbook and look at that when flying.

So it means for me some serious TESTING with the netbook connected for sure... thanks for pointing that out before I went airborne!!! Yikes! :o :? :shock:

I'm gonna do that type of testing with the netbook connected also... but I noticed... gadda keep hitting the rescan button cuzz that ain't a live number on the display... I kept moving the drone around and the number didn't change , then I hit the scan button again and baam! Duhhhhh ... that was the problem :?

Prolly same with mine--thanks for the tip. :)

Well I hooked-up again and got -80dBm at 200 feet, and though it was through a wall, that's still pretty underwhelming to me; afaict that's only 20% signal and "weak" of course. Gotta get it outside for a real test no doubt. My receive sensitivity is supposedly -94dBm, so this oughta work OK, but still... :|

BTW this time I plugged the Drone in when it was a good distance outside, and it came-up as Channel 1 which is what I expected the first time. Seems I'd forgotten about the local wifi in our garage (where my workshop/computer area is) and it is on Ch1 also. Which is why my Drone used Channel 6 the first time I tried this (I had plugged it up and connected and THEN walked it outside). All this stuff is becoming a lot for my old tired brain to keep track of!

Guys, have any of you heard about WiFi Plus antennas? They specialise in multi polarized antennas with better reception than even circularly polarized antennas in non line of sight applications.

Some field evaluation results on their site:

These antennas might be ideal for those of us who want to fly the drone in more built up environments (or around trees) where we don't have a clear line of sight back to the drone

In all my surfing lately vanquish I had not come-across those antennas and they are very interesting indeed. And not just for "non line-of-sight" but for what appears to me anyway to be much better vertical "reach" compared to other ants which are designed for horizontal range, not vertical.

I'm barely awake at this hour and can't tell which of the two types would be better for our application, the bullet-style or the omni-style. Maybe someone here is expert at interpreting the graphs in their .pdf spec files and can comment.

I think the larger omni style, the smaller bullet style is meant for portable devices like phones and laptops

I bought one of the multi-polarized ants from the developer website:

Note at the very bottom is a little gizmo that attaches to a rubber ducky ant and purportedly helps a lot ($20).

vanquish maybe you wanna re-post your last couple of posts in a new thread so we don't hijack DBS's any further. :o

I don't mind the hijack at all... that trident antenna looks really sweet... hope it works as well as it looks

:? Huh?

My head got to spinning yesterday when surfing on "multi-polarized" antennas. Man there is too much I don't know about RF. But I am very susceptible to a good sales pitch :oops: and I couldn't find any negative comments about Dr. Jack Nilsson's antennas except for some people who poo-pooed them out-of-hand (i.e. w/o experience) as "snake oil".

Anyway I found a deal on the Trident so grabbed it, and I may get one of those rubber duck attachments too as I think it might fit atop my 9dBi omni.

I've been focussed to-date on Signal Power but then read that Polarity was a major factor also in signal loss, and given our Drones' ants apparently are Horizontally polarized, it seems the couple vertical omnis I have here may not be the best to use. Though I did also yesterday angle my 9dBi omni to a horizontal position and it didn't seem to affect at least the signal strength at all.

Unfortunately it seems the only real data we can glean about the quality of our Drone's signals in-flight, is whether they crash, or they don't crash!!!

:twisted:

Thanks for letting this squat here a while longer anyway.

Oh btw in my surfing a guy from mpantenna was found to post on a RC airplane site that was talking I think about FPV stuff. Anway I may email him and see what he thinks about our unique WiFi challenges.

Give the rundown on how that antenna performs... really interested now

Hey DBS, has the weather cleared yet? very excited and keen to seen your results with range testing (dam weather):D
