What signal levels are required for LTE cellular connections?

The exact thresholds for maintaining an LTE connection or higher data speeds will vary per carrier.  The charts below provides general guidelines.  In order to see the current signal levels:
  1. Log into the Nodegrid appliance as admin
  2. Access the root shell: shell sudo su -
  3. Get a list of the available modem(s):  ls -l /dev/cdc-wdm*
  4. Get signal information for a specific modem: qmicli -d /dev/cdc-wdm0 --device-open-proxy --nas-get-signal-info
    1. Change cdc-wdm0 to reflect the specific modem's number; i.e. cdc-wdm1, cdc-wdm2, cdc-wdm3, etc
