If I understand correctly, here are some info related to WiFi and MIT MIT has some research related to WiFi radar -- use WiFi signal to "see through the wall", detect people or heart beat behind the wall:

They also have CAN radar course: [2]https://ocw.mit.edu/resources/res-ll-003-build-a-small-radar -system-capable-of-sensing-range-doppler-and-synthetic-aperture-radar-i maging-january-iap-2011/ Our openwifi also support feature similar: we can get CSI (channel state information) out of our chip (of course it is our own open source chip, we can have anything we want). The CSI could reflect some signal spatial propagation information. Apparently there is privacy/security issue of above WiFi signal processing technology. Think about detect what are inside your house by just receiving signal in a car parking outside your house. However, because openwifi is an opensource project, one of our user has developed "anti-sensing" solution based on our project. : [3]https://ans.unibs.it/projects/csi-murder/ If the AP in your home has our "anti-sensing" feature, the "see through the wall" won't work anymore! Beautiful thing, right? But unfortunately our current design is not a real chip yet (tape out, we call it). Currently it is run in FPGA verification platform (SDR -- software defined radio), which means quite expensive (~1000usd). We still needs lots of efforts (and funding) to make a real chip tape out. If we can make a chip, the cost could be as low as a normal WiFi chip, but it will be the first opensource WiFi chip!

You want to find some researchers from MIT to work on openwifi?

Or how I can find such researchers? It is about if mit can contribute to the openwifi card. https://github.com/open-sdr/openwifi _______________________________________________ libreplanet-discuss mailing list [email protected] https://lists.libreplanet.org/mailman/listinfo/libreplanet-discuss References 1. https://www.media.mit.edu/projects/seeing-through-walls-computer-vision/overview/#:~:text=Our group develops technologies that,on wireless signals, like WiFi.&text=capture through occlusions.-,To do so, we rely on wireless signals, like WiFi,returning to a wireless receiver. 2. https://ocw.mit.edu/resources/res-ll-003-build-a-small-radar-system-capable-of-sensing-range-doppler-and-synthetic-aperture-radar-imaging-january-iap-2011/ 3. https://ans.unibs.it/projects/csi-murder/ 4. x-apple-data-detectors://0/0
