LTE total RRU transmit power calculator
Background
The total transmit power of an LTE RRU (Remote Radio Unit) can be calculated using a combination of four other values: reference signal power (RSP), number of TX ports, bandwidth, and the value of p-b in LTE SIB2.
Both RSP and p-b can be found within a network's LTE SIB2, as seen below in a screenshot of Network Signal Guru:

Options other than total transmit power may be slightly inaccurate due to the nature of calculations involved.
