I have a quectel model: RM510QGLAAR13A01M4G_BETA_20230423A
It is in working order but I would like to understand better how metrics such as RSRP are calculated with the 4 antennas. Are they all used at the same time and the value is an average or just the best signal from the antenna with the best reception is considered?
Is there a way to make only one of the antennas active without physically blocking the other 3?
