Hello, friend!
I'm not sure what intra site power control means. But in terms of literal meaning and transmission: You can use the NMS, device boards, and optical modules to detect and control device power consumption at a site.
The related contents are as follows:

Inner loop power control in the uplink is the ability of the UE to adjust its output power in accordance with one or more TPC (transmit power control) commands received in the downlink.
transmit power control
A technical mechanism used within some networking devices in order to prevent too much-unwanted interference between different wireless networks.
If you don't get the answer you want, you can explain the question clearly.
Thanks!
