Good afternoon.
I have RBM33G with SIMCOM SIM7600E-H with the latest firmware.
Support for this modem is officially there.
There is no SINR field and its value in the Cellular tab.
But in the logs, this parameter is transmitted by the modem via the at command, which can be seen in the screenshot.
Can ROS developers fix this?
Thanks.

Re: LTE info SIMCOM SIM7600E-H
SINR is not 3GPP standardized quantity and different LTE chip vendors might have the calculations implemented differently (or not at all as it is not needed for communication with LTE network). SINR has its merits when correlating radio channel quality to achievable throughput, but RSRQ carries similar information.
You can read this article about relation between the two quantities.

I know the differences between RSRQ and SINR.
I wanted to clarify why the information from the modem comes in, but it is not parsed.
For example, with the Sierra Wireless MC7710, the SINR parameter is parsed and displayed in the Cellular tab.
