How much power does a PSU need?

This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10 W.

How much power does a PSU need during a quiescent period?

During quiescent periods—typically 5 ms to 100 ms—the PSU must minimize all load power with the basic functions of the antenna unit remaining active. It also must be able to ramp up to full power whenever the antenna wants to check for any active users within its range.

Why are small cells being deployed on streetlights and utility poles?

Small cells are being deployed on utility poles and streetlights, which have limited space for radios and cables. Meanwhile, there are similar constraints on macro sites operating at traditional sub-6 GHz frequencies.
