# AT&T debuts 5G channel sounder ‘Porcupine’ with NI | FierceWireless

I am afraid this is a “wounded” porcupine – many of the quills (beams) are missing! Using a lens antenna array for the sectors (as in our CAP-MIMO protototype below) would make the porcupine whole! Each “sector” spanned by a single horn antenna above, would be larger (to cover the holes in coverage) and spanned by many many more beams (16 shown below) – thereby replacing the missing quills (beams)!
