Maybe Cambium can use something like this in the next generation of PMP450m? I wonder how much one of these bad boys cost?
At WISPAPALOOZA, Blinq was showing (not working) a massive system with IIRC 72 staves. Ericsson had a unit (again, may have just been an antenna for show) with 128 staves. So Medusa is nowhere near the limit.
As to price, the others were comparable... in price per stave. You need a pretty big application for that to pay off.
