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

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. :

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!

Hello,
This is Xianjun Jiao, the author of openwifi
Not understand quite well about the question. 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.
