Find power of 4g signal V47A.01.01 modem

Hi, I'm using a 4g modem for access web, I wish know the power of 4g signal, I have look in the menus, but I don't have found anythings.
Someone can help me?

It depends on the protocol you are using.
For NCM you can run comgt -d /dev/YOUR_DEVICE and you'd get a number from 1 to 30 (best).
For 3G there is gcom info -d /dev/YOUR_DEVICE
For QMI try uqmi -d /dev/cdc-wdm0 --get-signal-info

Thanks, but I am really a novice... how to give commands?

From SSH.
