Phased array is definitely the way to go if you can get cost down. No moving parts means fewer hardware/mechanical failures and less noise
- nielsole 8y agoWhat is the difference between phased array and MIMO? Isn't MIMO a solved problem and shouldn't the technology be transferable to this use case?
- andbberger 8y agoA difference is that phased arrays need sub-wavelength tolerances in phase between emitters to work
