We have a HD4 Max installed on a vessel with both the Main and Aux antennas connected and 4 SIM card slots used on.
My question is about the signal strength indicator. Since we are a ship we use amplifiers to increase our range when we are further away from the coast.
Using amplifiers though means that the RSSI always comes in high, but if our signal is weak then obviously the SINR, RSRP and RSRQ can be low even though the RSSI is high.
Sometimes some of our SIM cards can have a good SINR/RSRP/RSRQ whilst others don’t.
The thing is the signal indicator seems to be purely based on the RSSI value which is always high for us. Is there anyway to change it so the quality indicator is based on something like SINR instead? I would like to be more strict and have connections with low SINR be disabled so only ones with high SINR values are used.
Here is a typical case of a SIM card which is reporting perfect signal but if you dig into the details you find that it is actually:
RSSI: -53dBm SINR: 0.0dB RSRP: -78dBm RSRQ: -17.0dB
Thanks in advance!
