AT commands and/or Modem Signal Quality

I have the MiFi with the latest Firmware (v3) and I love the new interface, setup was simple, it immediately was able to set up my Tmobile SIM…I see the General 4G signal meter…but where do I go to get specific info on the signal strength etc? I have an idea of signal level (like signal/noise in WiFi) before I add external anntena’s

If I install the cables/antenna…is there anything else I need to do?

Thank you.

I should note, that I am receiving a SNR of 55, which from what I read is good…I didn’t note what it was on the internal antenna…and I got 31 Mbps down and 29 Mbps up on speedtest.net. Which is better than with internal.

I coiled the lines underneath where the antennas are mounted to keep the cables clean (they were shot cables about 3"-5" and I am using TechToo external antenna’s. Below are the links to the parts…

You can use uqmi to check.

Thank you…I have read that any SN Ratio above 25 is really good…I have received 51-54 SNR using the external antennas above.

That did work, but it showed me a SNR of 184…is that even possible?

Thank you again.

Yes, it is possible. It showed me an SNR of 188.
