Quectel RM510Q LTE signal indoors
Posted: Sun Feb 19, 2023 4:15 pm
Just switched from a Sierra MC7455 to a Quectel and the modem responses to questions is confusing.
Firstly I have never been able to use 4G at my locale until today but it is not strong and is slow. So I am still running on 3G.
I did some tests and I got these readings.
Perhaps someone could be kind enough to help me interpret these results.
I am considering an external antenna.
