QuadRF is a phased array antenna that can see WiFi through walls, spot drones in the sky... and it's powered by a Pi 5 and FPGA board. Very neat device, we have a full video up on Geerling Engineering...

Full video here: And it's available for pre-order on Crowd Supply:

But can it help clear heavy WiFi congestion 😭

Could definitely add to it in TX mode :D

That would be simply.. next Level1 🙏😅

Wouldve been nice for them to be able to sell the card only

They might still; I think initially they want to have a full package and keep things simple. A lot of it will be open source, too (not sure on hardware side). Would love to see the MIPI code

I already have everything,and seeing pi5 prices, 500$ id hard to swallow,if they arent gonna sell the board,i will be waiting for the gerber files

What about being able to see humans through walls? They’ve supposedly been able to use regular WiFi routers for that so I’m assuming with a phased array it should be able to do it even more accurately.

Crazy I was just looking at your product on QuadRF | Crowd Supply, and this video popped up on X.

RF is one of those “boring” layers right up until somebody makes it visible. Then everyone suddenly remembers WiFi, walls, drones, and interference are real things.

Oh man…. This could probably see cell phones pretty easily too.

Superb for doing office walks to look for rogue access points

That shit is going to get Tweaked So quickly and be used to do the IRL wallhacks and AR glasses

Can you add a giant laser aimer… thanks!

What happens when Marge from Accounting saunters into the break-room next door and nukes her Hot Pocket?

@4nt1p4tt3rn You seeing this filthy sht? So dirty. I love it.

Wonder if you could do this by reverse engineering a COTS WiFi router instead of using that quad array antenna. Might get better resolution

Can it track golf balls in real time at high speed? @grok could this be adapted as an open source Trackman equivalent golf launch monitor?

Can we pause and appreciate this...

So this can help best way to arrange a mesh node?

wtf. This is rad and scary. How do you defend from this? @grok

This looks awesome. Why only 5.8ghz though?

Hella kool!

@0xocdsec I want this!! 🤩🇺🇦

Hi Mr G! You are the best. Maybe have your own channel or podcast. Just saying. Thank you Jeff too

Myst!

Very cool and important for health, scan your bedroom, office, bathroom, living rooms and kitchen to ensure levels are low. It would also be very useful for detecting anymore saturating your home with harmful levels of emf radiation when installed outside and rotating like radar

@AsanoDenji

Nice

Like snipers taking out cigarette smokers at night, very cool!

Take it out side at night away from the city and point it at the sky let’s see what it sees

Very cool!

Awesome

You have one you could lone or rent? I have a project that I would be interested in seeing if or where your array might fit. The intent is pulling off, at least the prototype, with 100% COTS equipment. This fits.

Excellent 👌

Dang that’s sexy
