Anafi AI 4G rssi specs

Hi, I would like to enquire about the 4G module/chipset used in the Anafi AI drone and its telemetry measurement specifications. I am using the ADB shell access functionality to retrieve cellular telemetry data from the onboard 4G SIM connection, as described in this post:
( Extraction of 4G/LTE RF parameters - ANAFI Ai - Parrot Developers Forum).

I would like to know the specifications of the parameters, i.e. range and measurement accuracy. Mainly the “rsrp_rssi” parameter, is its range from -100 to 0dB and what is it measurement accuracy? I was not able to find this in anafi ai’s whitepaper ( whitepaperanafiai.pdf)

Any insights or references would be greatly appreciated.
