Yes, I'm sure there are some tricky algorithms so it finds non adjacent subs to talk to simultaneously. They said you would need subs distributed across the sector to get maximum benefit.

Think about a single 2x2 sector. It can talk to only one SM. Now add another sector facing the same direction. You've doubled your capacity, right? Sure, but you're using twice the spectrum. Put up 3x 30-degree or 5x 20-degree sectors. More spectrum, more hardware. The cost of the hardware adds up, but is kind of a moot point. The spectrum, or lack of, is not so moot. > >> On 11/1/2016 9:05 PM, Kurt Fankhauser wrote: >> Also what I don't understand about Medusa, since it has a bunch of smaller sectors inside of it,, is the sectors inside of it running ABABABAB frequency re-use?
