Interesting video, thanks. Yes Ekahau survey and analysis tools are pricey! It's a small market. If it was just WiFi signal strength & spectrum congestion you were looking to survey, a 6GHz WiFi client is a cheaper option. It's when you are trying to track down non WiFi signals that are or may be causes for interference that it's nice to have general spectrum analyser tools. Looks like your software could turn the Hack RF one into a cheaper version of a signal hound BB60 real time analyser - these do 20Mhz real time FFT and swept analysis for wider bandwidths. These cost around $3k US last time I looked, but do have pretty accurate RF front end which of course is sacrificed with the cheaper device.
Very cool. The thing you pay for with Ekahau is the profiling of a potential wireless deployment - it'll take the really basic frequency profiling then overlay over building plans, modelling walls, materials and APs and topology. The actual RF spectrum analysis is pretty basic - you're probably further along.
hey mate, i just upgraded to a unifi U6 pro. holy shit the PHY rate is fast! 2402 mbps just off 2x2, so i can finally get gigabit file transfers over my LAN
Hello Paul, very interesting project and I do hope that you finish and release a Spectrum Analyser app. FYI... the Australian Communications and Media Authority (ACMA) is currently (March 2024) considering the use of the upper part of the 6 GHz spectrum - for which there are competing interests from wireless telcos and RLAN (ie. WiFi7) interests, manufacturers etc. It's not clear at this stage which interests get access to the spectrum and there are incumbent users in the band (eg. Telco microwave links and broadcasters Television Outside Broadcast (TOB) itinerant links).
Hello Thanks for posting information about RF hacking capabilities I wanted to know if the first program is available to the public? Or is the 3D spectrum library available to the public? Thank you
@@TallPaulTech You showed that the signal tapered off beyond 6.3 GHz as you reached into the 6.5 GHz range. I'm wondering if this is due to poor receiver sensitivity above 6.3 or if there is an internal filter that blocks over 6 GHz.
It would be it's signal path performance I'd say. The bandpass filter would just be the normal 20MHz one (I'd imagine) which is 20MHz at any frequency, because it gets mixed down by its LO to be the tuned frequency.@@GeorgeOu
If I wanted to expand it I would have. Should I explain RF, "gig", and all the other abbreviations I mentioned? I know what you should do... and it involves your hat.

Good video! Very interesting project)
Nice Work!
Wooow that's insane, we'll done
what an incredible app!!!
It will be one day when I finish it
@@TallPaulTech one day.. ;P
Great video!! What headset are you wearing?
It is beautiful and efficient
Did you use a library for 3D Spectrum?
Or did you create it yourself?
I want to use it inside a project
very interesting

I do hope I finish it too!
Internal 25MHz crystal, or something better?
Could you add a downconverter to drop the signal below 6ghz? But then again you still can't use that range in AU anyway 🤷
I was thinking exactly that, use an LO. This is what satellite dishes use to convert the 11-13GHz down to sub 1GHz frequencies.

I never really finished it to be honest.

Is this due to a bandpass filter?
Which bit... what?

I wish I understand what you are doing..
Well as I was always told, wish in one hand, shit in the other, and see which gets the fullest
Why does Australia limit Wifi 6 frequencies? I thought radio waves traveled the same even when you’re upside down.
FFT Fast Fourier transformation, may want to expand it, just for people who don't know.

There are already many videos on this including veritasium
You really like channel 69 huh? ;)
