>At low-band, it's often quoted as 20%, but when you get to mid-band it's a lot more. That's an interesting claim. What aspect of the 2-4 GHz stuff gives 5G spec a greater relative spectral efficiency up there? The only thing I can think of would be tighter specifications for equipment phase noise and phase noise going up with frequency and becoming the main problem.
