Measuring cell signal strength (rsrp) for booster placement -- can't find rsrp.

LTE service cell measurement doesn't show rsrp on iPhone Xr -- can it be found anywhere? I'm trying to locate the best placement for a SureCall Fusion-4Home cell signal booster, per the instructions, need to find the rsrp parameter under the LTE Serving Cell Measurement info, which has rscp and rssi but not rsrp. The rsrp is a measure of the strength of the cell signal. One enters the number @3001#12345#* to access a page of related info, that is, for instance, to get to the LTE Serving Cell Measurement info.

iPhone XR, iOS 16

The dialing code is dialing *3001#12345#* and not @3001#12345#

Understand RAT concerning Cellular Networks.

Cellular networks use different Radio Access Technologies (RATs) for communication. Common RATs include GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access), LTE (Long-Term Evolution), and 5G NR (New Radio).
Each RAT represents a different generation or technology level in mobile communication.
Network retention usually refers to a device's ability to maintain a connection to a specific network (e.g., GSM, CDMA, LTE) while moving between different areas or cells.

You may have checked the current LTE band/5G/4G/3G by dialing *3001#12345#* and pressing the call button and then selecting the Serving cell info option and then looked at MISC
